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.
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...
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%.
Agglomerate
Agglomerate rock is a type of sedimentary rock that forms through the accumulation and cementation of coarse fragments of various sizes, typically ranging from...
Oil Shale
Oil Shale is organic-rich sedimentary rocks that have contain kerogen (insoluble organic matter in sedimentary rock. When subjected to intense heat, these shales yield...
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...
