Crystals

To describe the geometry of crystals, so-called crystallographic axes are used. These axes define a three-dimensional coordinate system within the crystals' structure, and of course - as one would expect for describing three-dimensional bodies - there are 3 axes labeled a, b, and c.For example, one can describe a crystal face as part of a plane that lies parallel to …

Quartz | Common Minerals

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.
