Quartz was the mineral upon which the Stone Ages were based. With few exceptions, most early stone tools were fashioned of quartz. Outcrops of quartz that were suitable for tool manufacturing were targeted by some of the earliest known mining activities and the mined quartz was traded across vast distances, even before humans began to establish agricultural societies. Chert is a biochemical sedimentary rock made from microcrystalline quartz. It is very hard – registering a 7 on the Mohs hardness scale, and displays conchoidal fracturing. …Since cherts do not precipitate under high temperature conditions, hydrothermal events show a vertical change in diagenetic mineral assemblages. The amount of chert decreases with depth, which indicates that the prevailing temperature is increasing with depth (i.e., Chert α 1/depth; and Dolomite α depth; Fig. 3).The most common chemical sedimentary rock, by far, is limestone.
