GL101 Chapter Notes - Chapter 6: Depositional Environment, Diagenesis, Sediment Transport
Document Summary
Isostasy measured using continuously operated gps stations: recall isostasy is the gravitational equilibrium between the lithosphere and underlying asthenosphere which controls the relative height of land due to the overall thickness and density of the tectonic plate. If you add or take away weight, the plate (land) should fall or rise in response. This is true if we add or melt ice sheets or even relatively smaller quantities of liquid water: what is a sedimentary rock, sedimentary rocks are products of mechanical and chemical weathering. They account for about 5% (by volume) of earth"s outer 16 km: contain evidence of past environments. Commonly contain fossils: sedimentary rocks are important economically because they may contain: Raw materials for the construction industry: sedimentary rocks are the products of mechanical and chemical weathering. Mostly formed from mineral crystals and clasts (broken pieces), organic remains or rocks compressed or naturally cemented together.
