Chert Composition Chert is in most cases a biogenic rock it is made of siliceous tests of diatoms radiolarians siliceous sponge spicules etc Sometimes microscopic fossilized remains of these sea creatures may be preserved in these rocksDiatomaceous earth or diatomite is a light colored sedimentary rock composed chiefly of siliceous shells frustules of diatoms Diatomaceous earth is a soft and friable rock It leaves hands dusty if touched and has a fragile feel as if it has a delicate and light weight

The mineral phase of the diatomite contains a number of clay minerals like montmorillonite in a mixture with insignificant quantities of slightly chloritized montmorillonite illite and kaolinite Diatomite contains also non clay components as fine dispersed quartz and amorphous material the more probable sources of which are opal amorphous alumosilicates aluminum and iron hydroxidDiatomite Producers In a total of 29 countries produced commercial amounts of diatomite The United States was the leader producing an estimated 700 000 metric tonsCzechia Denmark and China each produced over 400 000 metric tons Argentina Peru and Japan produced 100 000 metric tons or
