[¦nän′kla‚stik] (geology) Of the texture of a sediment or sedimentary rock, formed chemically or organically and showing no evidence of a derivation from preexisting rock or mechanical deposition. Also known as nonmechanical.

What is the difference between clastic and non-clastic?

rocks that have been weathered, eroded, and deposited are called clastic rocks. Clasts are the fragments of rocks and minerals. ... Non-clastic rocks are created when water evaporates or from the remains of plants and animals. Limestone is a non-clastic sedimentary rock.

What is a non-clastic texture?

Non-clastic textures are found chiefly in rocks that have precipitated chemically from water (chemical sedimentary rocks), such as limestone, dolomite and chert. Other non - clastic sedimentary rocks include those formed by organisms (biochemical rocks), and those formed from organic material, such as coal.
