<h3 class="headings">ERB101 - Earth Systems</h3><br><br>
<p>
Earth Science impacts every aspect of modern life. Hence, the concepts of Earth Science
are fundamental not only to the field of Geology, but also to Environmental Science, natural
resource management, civil engineering and society at large. Earth Systems provides an
introduction to Earth Science, including earth materials, geologic history, geological and
physical geography process at the Earth's surface, and the complex interplay between the
lithosphere and landscapes. Additionally, the unit provides readily accessible examples of
the use of scientific reasoning for understanding complex natural systems. Hence, Earth
Systems is a foundation unit for further studies in Geology and Environmental Science, but
more importantly, serves as a broad introduction to the very world we live on and to the ways
of science in general. Such a background is highly desirable for any informed citizenry for
understanding complex issues of resource, environment, and societal development.

Bowen's Reaction Series arranges the silicate minerals in the order that they crystallise from a magma. The minerals at the top of the series crystallise from the melt at higher temperature than those
lower down. It contains a continuous series, (right hand limb), discontinuous series (left hand limb), and the residual phases that describe the reaction pathway of different silicate minerals.
The discontinuous series crystallises different minerals, with abrupt changes separating the different minerals due to a mineral reacting with the melt to form a different mineral (eg. Olivine reacting to crystallise pyroxene).
The continuous series always crystallises plagioclase, but the composition of the plagioclase varies from more calcic at higher temperatures and more sodic as the temperature decreases.
with the minerals at the bottom of the series being more stable, and less susceptible to weathering.
The residual phases are the minerals at the bottom and crystallise last. Bowen's reaction series also predicts the stability of minerals in the low pressure conditions at the Earth's surface,
<br /><br />
It should be noted that all reactions do not start crystallising olivine/anorthite-rich plagioclase and continue through until they crystallise quartz.
The actual reactions depend on many factors, such as the chemical composition of the melt, temperature, pressure, and amount of fractional crystallisation.
For example, basalts form from the crystallisation of olivine, pyroxene and calcic plagioclase meaning that crystallisation stopped without the series progressing.
If more fractional crystallisation were to occur, more intermediate and felsic minerals can crystallise.

<h2 class="theoryHeadings" id="classification">Classification of Minerals</h2>
<p>
The classification of minerals is based on their chemistry. The following mineral classes are based on the character of their common anions:</p>
<li><p>Silicates (SiO<sub>4</sub><sup>4-</sup>)</p></li>
<li><p>Oxides (O<sup>2-</sup>)</p></li>
<li><p>Sulfides (S<sup>2-</sup>)</p></li>
<li><p>Sulfates (SO<sub>4</sub><sup>2-</sup>)</p></li>
<li><p>Halides (Cl<sup>-</sup>)</p></li>
<li><p>Fluorites (F<sup>-</sup>)</p></li>
<li><p>Phosphates (PO<sub>4</sub><sup>3-</sup>)</p></li>
<li><p>Carbonates (CO<sub>3</sub><sup>2-</sup>)</p></li>
<li><p>Native elements, e.g. Au.</p></li>
<p><br />
The relative abundance of elements in the Earth’s crust (? Composition and structure of Earth) determines which minerals form.
As we can see in table x, oxygen is the most abundant anion in the Earth’s crust.
Thus, the crust can be seen as a tight package of oxygen anions (O<sup>2-</sup>), which are bonded by larger cations,
such as Si<sup>4+</sup>, Mg<sup>2+</sup>, or Al<sup>3+</sup>.
The way atoms are packed together depends on the cation to anion radius ratio (Rx/Rz).
With oxygen as the major anion, specific coordination and coordination polyhedra can be expected for different cations.

The heat contained within the Earth is generated by two main sources: the formation of the Earth,
and the decay of radioactive isotopes. The Earth was formed by the accretion of a large number of
planitesimals as it cleared its orbit. The impact of those planitesimals generated a large amount
of heat which is still being lost from the Earth’s core today. The other source of heat comes
from the radioactive decay of elements within the crust and mantle of the Earth.
The primary radioactive isotopes in the Earth are uranium-235, uranium-238, thorium-232,
and potassium-40. Radioactive decay is the dominant form of heat flow at the surface of the Earth,
providing approximately 80% of the heat budget.
<br /><br />
The temperature of the Earth changes from around 0°C at the surface to over 5000°C in the core.
The geothermal gradient in the crust is approximately 30°C per kilometre in the crust on average,
however there is significant local variation due to things such as the conductive abilities of the
rocks at particular locations, as well as the presence of nearby magmatic intrusions.
The geothermal gradient in the mantle reduces significantly, down to approximately 0.3°C/km.
The base of the lithosphere is defined by the 1000°C isotherm. The base of the mantle is at
approximately 2800°C.
<br /><br />
The method of heat transfer changes throughout the Earth. There are three main mechanisms for
heat transfer in the Earth: conduction, convection, and radiation. Starting in the inner core,
the main method of heat transfer is by conduction through the solid material. In the liquid,
outer core heat transfer is by both conduction and convection. The mantle is dominated by convection,
which is the driver of plate tectonics. The crust is again dominated by conduction, and finally
energy escapes the Earth to the atmosphere by radiation.
<br /><br />
Pressure in the Earth continually increases with depth, according to the formula P = gρz,
where g is the gravitation field strength, ρ is the density and z is the depth. The main
difference in the pressure gradient is cause by the different lithologies in the layers
of the Earth. The average density of continental crust is approximately 2.7g/cm3 and
is ~3.0 g/cm3 in oceanic crust, and increases to about 3.3 g/cm3 in the mantle.
The increase of pressure with depth in the Earth affects the dominant mineralogy, as
well as the increase of the melting point of different minerals.
<br /><br />
The structure of minerals, such as olivine becomes unstable as pressure increases.
Below about 410km olivine becomes unstable and transforms into wadsleyite, which has the
same chemical composition as olivine, but has a different crystal structure. As depth
increases, wadsleyite transforms to ringwoodite, which subsequently transforms into
perovskite at about 600km.
<br /><br />
At higher pressure, minerals have a higher melting point. The effect is this phenomenon
is that the dominant method of melting in the mantle is not by increasing the temperature
past its melting point, but by decompression. Due to convective processes in the mantle,
as parts of the mantle rise the decrease in pressure lowers the melting temperature and
can cause the mantle to melt.

<h2 class="theoryHeadings" id="structureofearth">Structure of Earth</h2>
<p>
The Earth's structure is differentiated in three distinct layers: the core, mantle, and crust. The layers are distinguished by a change in the velocity of seismic waves at their boundaries.
The crust is the upper most part of the earth, with depths ranging from an average of 7km in in the oceans, to an average of 38km in continental crust.
The crust thickens underneath mountain ranges, and can reach depths of 90km underneath the Himalayas. The composition of the crust also differs between oceanic and
continental environments. Ocean crust is young mafic crust dominated by basalts and gabbros that is recycled regularly(~300Ma) due to subduction processes.
Continental crust is much more varied in structure and composition than oceanic, but has an overall average composition of granodiorite.
<br /><br />
The boundary of the crust and mantle is defined by the Mohorovičić discontinuity, commonly referred to as the Moho.
It is defined by a sharp increase in seismic wave velocity, due to a change in material properties between crustal rocks and mantle rocks. The mantle is dominated by
silicate minerals that are rich in iron and magnesium, chiefly pyroxenes and polymorphs of olivine, forming peridotite. The mantle, while solid, behaves plastically,
allowing to flow at very slow rates.
<br /><br />
The core is distinguished by the absence of S waves, leading to the inference that the core is liquid. The core is separated into the outer core and the inner core.
The outer core is liquid dominated by iron and nickel. The inner core is solid, as determined by the strong refraction of P waves at the inner core-outer core boundary,
and was formed by crystalizing minerals from the liquid part of the core as the Earth cools.
<br /><br />
The crust and mantle are also further distinguished by material properties into the lithosphere, asthenosphere, and mesosphere. The chemical composition is
uniform throughout the mantle though, but changes in pressure and temperature determine which polymorphs will exist at different depths.
The lithosphere contains the crust, and the upper part of the mantle down to ~100km under oceanic crust, and 200-300km under continental crust (Twiss & Moores, 2007).
The lithosphere-asthenosphere boundary is defined by the 1300K isotherm, which is the temperature where olivine starts to behave viscously.
The rocks in the mesosphere are under more pressure than those in the asthenosphere, so no longer behave viscously.</p>

series describes the sequence of minerals that crystallize as the temperature of the magma decreases. The discontinuity of each of the
crystallization sequences reflects the different melting/crystallization temperatures of the minerals, and the change in composition of the
residual magma, as the early crystallizing phases are being fractionated from the melt. The continuous series always crystallizes <a href={% url url_extender|add:plag.url plag.id %}>plagioclase</a>,
but the composition of the plagioclase changes from more calcic (i.e. anorthite) at higher temperatures to more sodic (i.e. albite) as the
temperature decreases. The compositional change during mineral growth can be recorded in compositional zoning of plagioclase
crystals. The minerals at the bottom of Bowen’s reaction series crystallize last and are more stable,
and less susceptible to weathering. Thus, Bowen's reaction series also predicts the stability of minerals in the
low pressure conditions at the Earth's surface.
<br /><br />
It should be noted that all reactions do not start crystallising olivine/anorthite-rich plagioclase and continue through until they crystallise quartz.
The actual reactions depend on many factors, such as the chemical composition of the melt, temperature, pressure, and amount of fractional crystallisation.
For example, basalts form from the crystallisation of olivine, pyroxene and calcic plagioclase meaning that crystallisation stopped without the series progressing.
If more fractional crystallisation were to occur, more intermediate and felsic minerals can crystallise.

An important characteristic of minerals is their crystallinity that is defined by the 3-dimensional, periodic structure of their atomic/ionic
components. (Note that some substances, e.g. opal or obsidian, do not form crystals, but are amorphous.
We sometimes refer to them as mineraloids)
<br /><br />
The smallest translatable unit cell of a crystal is defined by the crystal axes a, b and c and corresponding angles a, ß and γ.
There are seven systems of crystal axes called the seven crystal systems.
There are 14 crystal lattices, called the Bravais lattices that describe different possibilities of
distributing lattice points in the unit cells of the seven crystal systems. Among the seven crystal systems, 32 crystallographic
point groups (or crystal classes) are distinguished based on the possible combination of symmetry operations, such as reflection,
rotation, inversion and rotoinversion, within 3-dimensional space. Combination of the 14 Bravais lattices and the 32 point groups result in 230 space groups,
when further glide plane and screw axes symmetry elements are included. The space groups describe all possibly existing crystal and 3-dimensional structures.
<br /><br />
The crystal form arises from the symmetry elements that define the shape of the unit cell. Length and angle of the
unit vectors describe the shape of the unit cell for each crystal system. The external shape of a particular crystal is called crystal
habit and essentially dependent on the physical-chemical framework conditions during crystal growth.

<p>
Earth, like the Sun and the other planets of our Solar System formed around 4.6 billion years ago from part of a giant molecular
cloud - the cosmic debris of a massive supernova. Out of matter that coalesced in the center of the molecular cloud due to
gravitational collapse emerged the proto-Sun and a surrounding disk of dust and gas. Attraction forces within this rotating
protoplanetary disk that fed the young Sun, led to the accretion of progressively growing objects and planetesimals.
Increasing mass and gravitational forces of the growing planetary bodies resulted in interactions and disturbance in their orbits,
ultimately giving rise to larger collisions.
<br /><br />
Earth, as a terrestrial inner planet formed relatively close to the Sun through the
accumulation of rather heavier matter, whereas the outer planets formed from gas that had been blown away in more distal
regions of the solar system (solar wind). Continuous bombardment and larger impacts – including one that led to the
formation of the Moon -, and the radioactive decay within the Earth heated the planet resulting in partial melting.
Different melting temperatures and density contrasts led to gravitational segregation of a heavier iron core and a lighter
silicate mantle. Further chemical differentiation by partial melting of the mantle led to the formation of Earth’s proto-crust.
The Earth’s layering into core, mantle and crust due to this early differentiation remains an essential
feature of the Earth’s structure.

as well as the increase of the melting point of different minerals.
<br /><br />
The structure of minerals, such as olivine becomes unstable as pressure increases.
Below about 410km olivine becomes unstable and transforms into wadsleyite, which has the
same chemical composition as olivine, but has a different crystal structure. As depth
increases, wadsleyite transforms to ringwoodite, which subsequently transforms into
perovskite at about 600km.
The structure of minerals, such as <a href={% url url_extender|add:olivine.url olivine.id %}>olivine</a> becomes unstable as pressure increases.
Below about 410 km olivine (Mg<sub>2</sub>SiO<sub>4</sub>) becomes unstable and transforms into wadsleyite (Mg<sub>2</sub>SiO<sub>4</sub>),
which has the same chemical composition as olivine, but has a different crystal structure. As depth increases,
wadsleyite transforms to ringwoodite (Mg<sub>2</sub>SiO<sub>4</sub>) at ~520 km, which subsequently transforms into silicate perovskite
(MgSiO<sub>3</sub>) and magnesiowuestite (MgO) at about 660km depth. The increase in density is observed in an increase in the
velocity of P- and S-waves.
<br /><br />
At higher pressure, minerals have a higher melting point. The effect is this phenomenon
is that the dominant method of melting in the mantle is not by increasing the temperature
past its melting point, but by decompression. Due to convective processes in the mantle,
as parts of the mantle rise the decrease in pressure lowers the melting temperature and
can cause the mantle to melt.

The Earth's structure is differentiated in three distinct layers: the core, mantle, and crust. The layers are distinguished by a change in the velocity of seismic waves at their boundaries.
The crust is the upper most part of the earth, with depths ranging from an average of 7km in in the oceans, to an average of 38km in continental crust.
The crust thickens underneath mountain ranges, and can reach depths of 90km underneath the Himalayas. The composition of the crust also differs between oceanic and
continental environments. Ocean crust is young mafic crust dominated by basalts and gabbros that is recycled regularly(~300Ma) due to subduction processes.
Continental crust is much more varied in structure and composition than oceanic, but has an overall average composition of granodiorite.

The boundary of the crust and mantle is defined by the Mohorovicic discontinuity, commonly referred to as the Moho. It is defined by a
sharp increase in seismic wave velocity, due to a change in material properties between crustal rocks and mantle rocks.
The mantle is dominated by silicate minerals that are rich in iron and magnesium, chiefly
<a href={% url url_extender|add:diopside.url diopside.id %}>pyroxenes</a> and polymorphs of
<a href={% url url_extender|add:olivine.url olivine.id %}>olivine</a>,
forming peridotite. The mantle, while solid, behaves plastically, allowing to flow at very slow rates.

The core is distinguished by the absence of S waves, leading to the inference that the core is liquid.
The core is separated into the outer core and the inner core. The outer core is liquid dominated by iron and nickel.
The inner core is solid, as determined by the strong refraction of P waves at the inner core-outer core boundary, and was formed by
crystallizing minerals from the liquid part of the core as the Earth cools.

The crust and mantle are also further distinguished by material properties into the lithosphere, asthenosphere, and mesosphere. The chemical composition is
uniform throughout the mantle though, but changes in pressure and temperature determine which polymorphs will exist at different depths.
The lithosphere contains the crust, and the upper part of the mantle down to ~100km under oceanic crust, and 200-300km under continental crust (Twiss & Moores, 2007).
The lithosphere-asthenosphere boundary is defined by the 1300K isotherm, which is the temperature where olivine starts to behave viscously.
The rocks in the mesosphere are under more pressure than those in the asthenosphere, so no longer behave viscously.</p>
