What are the clastic sedimentary rocks?: conglomerate, breccia, sandstone, shale, mudstone
What are the chemical/biochemical sedimentary rocks?: oolitic limestone, fossiliferous limestone, chert, rock salt, rock gypsum, coal
What is the sedimentary environment of conglomerate?: alluvial fan, river channel, high energy beach
What is the sedimentary environment of breccia?: landslide deposit, crushed fault zone, glacial deposit
What is the sedimentary environment of shale?: lake, lagoon, flood plain, distal delta, shallow marine
What is the sedimentary environment of mudstone?: lake, lagoon, flood plain, distal delta, shallow marine
What is the sedimentary environment of oolitic limestone?: shallow marine
What is the sedimentary environment of fossiliferous limestone?: off-shore, warm, shallow sea with abundant marine life
What is the sedimentary environment of chert?: deep marine
What is the sedimentary environment of rock salt?: cut-off sea, warm, arid climate
What is the sedimentary environment of rock gypsum?: cut-off sea, warm, arid climate, associated with rock salt
What is the sedimentary environment of coal?: swamp
What is the composition of conglomerate?: -rock fragments
-mineral grains: chert, quartzite, quartz common
What is the composition of breccia?: -rock fragments
-mineral grains: chert, quartzite, quartz common
What is the composition of sandstone?: -quartz, feldspar
-rock fragments in varying proportions
What is the composition of shale?: quartz, clay minerals
What is the composition of mudstone?: quartz, clay minerals
What is the difference between conglomerate and breccia?: sedimentary environment & conglomerate (rounded grains) vs. breccia (angular grains)
What is the difference between shale and mudstone?: shale is laminated, mudstone is massive (no outward crystalline structure)
What is the texture of conglomerate/breccia?: coarse-grained, poor sorting
What is the texture of sandstone?: medium grained, excellent to poor sorting
What is the texture of shale/mudstone?: fine-grained
What is the texture of oolitic limestone?: -medium-grained
-excellent to poor sorting
What is the texture of fossiliferous limestone?: poorly sorted shell and fossil fragments
What is the texture of chert?: -fine-grained
-very well sorted
What is the texture of rock salt?: fine to coarse grained
What is the texture of rock gypsum?: -fine to coarse grained
-crystalline
What is the texture of coal?: fine to coarse grained
What is the composition of oolitic limestone?: small calcite spheres
What is the composition of fossiliferous limestone?: calcerous fossil shells, calcite, clay minerals
What is the composition of chert?: quartz (silica)
What is the composition of rock salt?: halite
What is the composition of rock gypsum?: gypsum
What is the composition of coal?: preserved plant materials
