Sedimentary Rocks: Formation, Types and Examples

Sedimentary rocks are the most common rock types which are freely exposed on the earth’s surface They are formed from other rock materials since they are made up from the buildup of weathered and eroded pre-existing rocks The weathering, erosion and the eventual compaction of igneous, metamorphic or formerly structured sedimentary rocks among other biological sedimentations leads.

Breccia

Types Sedimentary Sedimentary breccia is a type of clastic sedimentary rock which is made of angular to subangular, randomly oriented clasts of other sedimentary rocks A conglomerate, by contrast, is a sedimentary rock composed of rounded fragments or clasts of pre-existing rocksBoth breccia and conglomerate are composed of fragments averaging greater than 2 millimetres (0079 in).

The Serpentine Family of Rocks

Thus the origin of the material may be igneous or sedimentary, but, whereas the igneous rocks pass directly into serpentine, the sedimentary ones first pass through an intermediate metamorphic stage (hornblende-schists, etc), and are then converted This also explains in part at least the origin of the chromium and nickel.

Sedimentary Mineral Deposits

Mechanical Deposition of Sedimentary Mineral Deposits In some cases, the ore mineral, on account of its resistance to weathering and its hardness, survived the destruction of many of the rock minerals; and, during sedimentation, on account of its weight, it was sorted out from the fragments of quartz and other resistant minerals Thus, the ore-mineral was deposited, without being chemically.
