Presentation transcript:

Exam 3 Review Chemical Weathering: hydrolysis, hydration, carbonation, solution, oxidation-reduction Solubility relationships: pH,redox reactions, equilibrium constants Goldich’s stability series Clay mineral genesis Chemical weathering of common silicate minerals (e.g. olivine, pyroxene, feldspar, quartz) Acid-mine drainage Black smokers; seafloor alteration and hot springs

Exam 3 Review Sedimentary Rocks: clastic rocks- shale, siltstone, sandstone (various types), conglomerate/breccia; biochemical-limestone; chemical- sulfates and chlorides, dolomite, banded iron formation (BIF) Mechanical and chemical weathering, plus transport (erosion) Long and short transport systems Continental shelf, slope, rise, and abyssal plain Active and passive continental margins Bedding features Types of basins Indices of maturity; mineralogy, roundness and sorting Porosity, permeability, compaction, cementation Diagenesis

Exam 3 Review Biochemical sedimentary rocks – limestones Carbonate secretion – shells, corals, etc. Carbonate compensation depth (CCD) Micrite, oolitic limestone, fossiliferous limestone Chemical sedimentary rocks- Gypsum and salts – salina, sabkha, deep-water models Banded iron formation – Fe transport, oxidation, deposition, age and importance for interpretation of Earth’s atmosphere
