V. Sediment and Sedimentary rocks

1. size - Table 6.1
   1. gravel >2mm
   2. sand 1/16 - 2 mm
   3. mud <1/16 mm
      • silt 1/256-1/16 mm
      • clay <1/256 mm
2. development
   1. processes
      • erosion
      • transport
      • deposition
   2. effects
      • grain size
      • rounding
      • sorting
      • composition
   3. maturity

1. compaction
2. cementation

1. Detrital - clastic texture, generally dominated by quartz and clay minerals

   size	basic	unusual texture	unusual composition
   gravel	conglomerate	breccia	------
   sand	sandstone	-------	arkose
   mud	mudstone	shale	-------

2. Chemical
   1. carbonates - limestone
      • biochemical
        1. fossiliferous limestone
        2. coquina
        3. chalk
      • oolitic limestone
   2. evaporites
      • rock salt
      • rock gypsum

3. other
   1. chert
   2. amber
   3. coal

1. layers, strata, beds
2. sedimentary structures
