Clastic Sedimentary Rocks
Clastic sedimentary rocks are formed from the buildup of clatics: small pieces of fragmented rocks deposited as a result of mechanical weathering then lithified by compaction and cementation. Examples of Clastic sedimentary rocks include sandstone, shale, siltstone, and breccias.
Breccia
Breccia is a rock shaped from angular gravel and boulder-sized clasts cemented collectively in a matrix. The angular nature of the clasts suggests that they have now not been transported very far from their source. There are numerous modes of formation for breccia. Some constitute consolidated material accumulated on steep hill slopes or on the foot of cliffs.
Greywacke
Greywacke is variation of sandstone that saperate from other to hardness, dark color, and poorly sorted angular grains of quartz and feldspar. Generally found in Palezoic strata. Generally larger grain can be sand clast. Matrix material more than 15%.
Shale
Shale is a laminated or fissile clastic sedimentary rock that composed of predominance of silt and clay other minerals , especially quartz and calcite....
Siltstone
Siltstone is a clastic sedimentary rock that formed from grains whose sized between that of sandstone and mudstone. It can found different environmental conditions...
Coquina
Coquina is a sedimentary rock that is primarily composed of fragmented shell and coral debris. The name "coquina" is derived from the Spanish word...
