The Story of Sedimentary Rocks
Sedimentary rocks form from the compaction and cementation of sediments & chemical precipitation.
|Clastic: Made From Pieces||Chemical: Minerals Precipitate||Organic: Living Materials|
|Conglomerate: Large Sediments||Compact limestone: Grains of Calcite||Coal: Plant Remains|
|Sandstone: Composed of Quartz||Rock Salt: Crystals of Halite||Shell Limestone: Shell Fragments|
|Shale: Tiny Flakes, Silt|
are naturally sorted by water.
Larger pieces fall out in rougher water. (Conglomerate)
As the water slow, sand is deposited. (Sandstone)
Only in the calmest water are the flakes and silts deposited. (Shale)
ROCK: a group minerals bound together
|Light Colored Quartz||Dark Colored Biotite Mica||Pink Colored Feldspar|
|All Three Are In Igneous Granite||All Three Are In Sedimentary Sandstone||All Three Are In Gneiss|
