    ERB101 - Earth Systems



    +

    + 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

    +

    + 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, +

    + 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. +

    Classification of Minerals

    +

    + The classification of minerals is based on their chemistry. The following mineral classes are based on the character of their common anions:

    +

  • Silicates (SiO44-)

    • +

  • Oxides (O2-)

    • +

  • Sulfides (S2-)

    • +

  • Sulfates (SO42-)

    • +

  • Halides (Cl-)

    • +

  • Fluorites (F-)

    • +

  • Phosphates (PO43-)

    • +

  • Carbonates (CO32-)

    • +

  • Native elements, e.g. Au.

    • +


    + 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 (O2-), which are bonded by larger cations, + such as Si4+, Mg2+, or Al3+. + 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. +

    Pressure and Temperature

    +

    + 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. +

    + 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. +

    + 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. +

    + 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. +

    + 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. +

    + 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. +

    Structure of Earth

    +

    + 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 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. +

    + 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. +

    + 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.

    + + + + + + + +
    +

    Cyclosilicates

    +

    + + The cyclosilicates form rings of linked [SiO4]4- tedrahedra with either [Si3O9]6-, + [Si4O12]8-, or [Si6O18]12- configurations. Cordierite with the + chemical formula (Mg,Fe)2Al4Si5O18 represents an example of the cyclosilicate group. +

    +
    +

    Inosilicates

    +

    + + In the inosilicates, [SiO4]4- tedrahedra are linked as chains, which in turn are linked together by cations. + Single-chain inosilicates form [Si2O6]4- groups, and double-chain inosilicates + form [Si4O11]6- groups. Pyroxenes, e.g. diopside with the chemical formula + CaMgSi2O6, are single-chain, and amphiboles, e.g. hornblende + (Ca2(Mg,Fe,Al)5(Al,Si)8O22(OH)) or actinolite + (Ca2(Fe,Mg)5Si8O22(OH)2) are double-chain inosilicates. +

    +
    +

    Nesosilicates

    +

    + + In the nesosilicate group, [SiO4]4- tedrahedra are isolated from each other and share their oxygens + with octahedral groups, which contain cations, such as Mg2+, Fe2+, or Ca2+. A common + rock-forming mineral of the nesosilicate group is + olivine with the chemical formula + (Mg,Fe)2SiO4. +

    Phyllosilicates

    +

    + + Phyllosilicates comprise sheets of [SiO4]4- tedrahedra rings, where three of the four oxygens of + each tedrahedrons are shared resulting in [Si4O10]4- groups. Biotite with the + chemical formula K(Mg,Fe)3(AlSi3O10)(F,OH)2 is a common rock-forming phyllosilicate. +

    Structure of Earth

    -

    - 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 + pyroxenes and polymorphs of + olivine, + forming peridotite.

    - 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.
