why do chemical sedimentary rock have a non-clastic texture?

Question

science

Answer 1

A clastic rock is a sedimentary rock formed of particles deposited by water, wind, ice, gravity. The particles themselves would give the rock texture--think of the gritty surface of a sandtone. Detrital texture is described by size, shape, and composition or the sorting of the redeposited particles.

A chemical sedimentary rock is formed by precipitating from water solution. They precipate "in place", and are not formed by redeposited particles like clastic rocks. These include evaporites, opal, some carbonates, iron oxides, etc. Stalactites are examples. Dried up lake beds form flat layers of evaporites, another example. Chemical textures are usually crystalline with some special descriptions like pisolitic or oolitic.

The category not mentioned is that of biological sedimentary rocks--composed largely of plant or animal material.

Answer 3

Your question confuses me. I can think of several types of sedimentary rocks that can be clastic. Limestone is likely the sedimentary rock where you're most apt to note this property. Rarely Dolomite will present thus.

Hi. Because of crystalline particles. : http://hyperphysics.phy-astr.gsu.edu/hbase/geophys/sedime.html
