Some Special Clastic Rock Types: Some Special Clastic Rock Types Arkose Feldspar-Rich Breccia Angular Fragments Graywacke Angular, Immature Sandstone Maturity: Maturity Stability of Minerals Rock Fragments Rounding or Angularity Sorting Removal of Unstable Ingredients - Mechanical Working Diagenesis: Diagenesis Diagenesis: Diagenesis Compaction Cementing Quartz Calcite Iron Oxide Clay Glauconite Feldspar Alteration Limestone - Dolomite Plagioclase – Albite Recrystallization Limestone Chemical Sediments: Chemical Sediments Evaporites -Water Soluble Halite Gypsum Calcite Precipitates Example: Ca(sol'n) + SO4 (Sol'n) = CaSO4 and#x19; Gypsum Limestone Iron Formations Alteration After Deposition Dolomite Biogenic Sediments Limestone - Shells, Reefs, Etc. Organic Remains Coal Petroleum Fossil Fuels: Fossil Fuels Coal Seams, Utah: Coal Seams, Utah Coal: Coal Delta, continental environments Carbonized Woody Material Often fossilized trees, leaves present Plant Fragments Are Often Visible in Coal: Plant Fragments Are Often Visible in Coal Petroleum: Petroleum A hydrocarbon molecule What organisms make these? Answer: None Petroleum: Petroleum Lots of organisms make these, however Fatty Acids Probable source: Marine plankton Petroleum Traps: Petroleum Traps Facies Changes: Facies Changes Landforms Associated with Sedimentary Rocks: Landforms Associated with Sedimentary Rocks Mesa Flat-topped hill capped with hard rock Cuesta Gently-tilted layer of hard rock: Door Peninsula The gentle upper slope, on top of the layer is called the dip slope Hogback A sharp ridge of hard rock, edge of a steeply-dipping layer Mesas, Utah: Mesas, Utah Grandfather Bluff, Wisconsin: Grandfather Bluff, Wisconsin Cuestas, Wyoming: Cuestas, Wyoming A Hogback, Wyoming: A Hogback, Wyoming Flatirons, Boulder, Colorado: Flatirons, Boulder, Colorado Garden of the Gods, Colorado: Garden of the Gods, Colorado You do not have the permission to view this presentation.
