Rocks and Minerals: Everyday Uses

Glass is formed by melting quartz, the primary mineral found in sand. Sand is all that's left over after granite is ground down by streams, rivers, and the action of ocean waves. As the mineral quartz, silica is very hard, which is why it stays intact in sand, even as all of the other minerals from granite are destroyed.

2.4: Mineral Basics

When identifying a rock you must first identify the individual minerals that make up that rock. Minerals are naturally occurring, inorganic solids with a definite chemical composition and a crystal lattice structure. Although thousands of minerals in the earth have been identified, just ten minerals make up most of the volume of the earth's ...

Uncovering the creep deformation mechanism of rock-forming minerals

Creep is a process where deformation increases under constant stress and generally, the laboratory creep tests of rocks have three stages, namely, primary (transient) stage, secondary (steady-state) stage and tertiary (accelerated) stage [2].Nevertheless, the tertiary creep phase may not exist at low temperature, low stress and low pore-water pressures.
