Sediments & Sedimentary Rocks
Why study them?
• Cover vast areas of earth’s surface
•Continents and ocean floors
• Host of many high-value resources:
•Groundwater,oil, gas, coal, mineral deposits (U)
• Provide records of past surface processes:
•Paleo-climate, -ocean, -tectonics
• How sedimentary rocks form
• surface processes; weathering
• “source to sink”
• Lakes and oceans: “chemical mixing vats”
• Sedimentary basins
• Sedimentary environments
• Sedimentary structures
• Burial and diagenesis
• Classification schemes
