Pure diatomite is white or nearly white and quite soft, easy to scratch with a fingernail. When crumbled in water it may or may not turn gritty but unlike degraded volcanic ash, it doesn't turn slippery like clay. When tested with acid it will not fizz, unlike ...

Biochemical sedimentary rocks are a special kind of chemical sedimentary rock wherein the constituent particles were formed by organisms (typically as organic hard parts, such as shells), which then became sedimentary particles. Examples of this special kind of sedimentary rock include chalk, fossiliferous limestone, and coquina.Chalk is a sedimentary rock of unusually high homogeneity on the scale where physical properties are measured, but the properties fall in wide ranges. Chalk may thus be seen as the ideal...…
