Home Sedimentary Rocks 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.

Sandstone

An Ancient Record Written in StoneSandstone is one of the most widespread sedimentary rocks on Earth, formed through the accumulation and cementation of mineral...

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%.

Limestone

Limestone is a sedimentary rock such as greater than 50% calcium carbonate ( calcite - CaCO three). There are many exceptional kinds of limestone formed thru a ramification of tactics. Limestone may be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by using marine organisms including algae and coral

Conglomerate

Conglomerateis a sedimentary rock shaped from rounded gravel and boulder sized clasts cemented collectively in a matrix. The rounding of the clasts indicates that they've been transported a long way from their authentic source (e.G. Through a river or glacier), or that they've resided in a high energy surroundings for a while
Breccia

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.
