· 1. Introduction. During the technological study of the quartz assemblage of the Howiesons Poort layer Grey Sand (GS) of Sibudu Cave, a new morphotype, the so-called micro-notch, was identified (de la Peña and Wadley, 2014a).These notches measure less than 3 mm in length, and mostly occur on automorphic (crystal) quartz.

Silicon dioxide (SiO 2 ), commonly known as silica, is found naturally in several crystalline forms, the most notable being quartz. Additionally, when silicon dioxide is manufactured without the crystalline structure, it forms what is known as fused silica. Fused silica is a non-crystalline (or amorphous) form of silicon dioxide and is produced

Jewelry: In jewelry, quartz is often used as a gemstone, while silica is used to make glass. Quartz is preferred for gemstones because it has a higher clarity and hardness, making it more valuable. Silica is preferred for glass because it has a lower melting point and can be easily molded into different shapes.

· Quartz watches work in a very different way to pendulum clocks and ordinary watches. They still have gears inside them to count the seconds, minutes, and hours and sweep the hands around the clockface. But the gears are regulated by a tiny crystal of quartz instead of a swinging pendulum or a moving balance wheel.
