Feldspar Distinctions, Characteristics amp; Identification

The main mineral that might be confused with feldspar is quartz. Besides hardness, the biggest difference is how the two minerals break. Quartz breaks in curvy and irregular shapes (conchoidal fracture). Feldspar, however, breaks readily along flat faces, a property called cleavage. As you turn a piece of rock in the light, quartz glitters and feldspar flashes.

Mineral Gallery THE TWINNED MINERALS

Twinning often has a dramatic effect on the outward symmetry of the mineral either by raising or lowering the symmetry. Twinning can make an orthorhombic mineral appear hexagonal or make a trigonal mineral appear monoclinic. There are two general types of twin styles; contact and penetration. Contact twins have a composition plane (the twin plane) that forms at the boundary between the two twins.

Native lead is rare; lead is far more commonly found and mined as the lead sulphide mineral galena. The Romans named the refined metal 'plumbum' and used it for pipes in plumbing. Its major use today is in lead acid batteries and for radiation shields. It is also a constituent of low melting alloys. Native lead is somewhat ductile and very malleable.

Types of Twinning in Minerals

When the multiple twins are not parallel they are cyclic twins. Albite, calcite, and pyrite often show polysynthetic twinning. Closely spaced polysynthetic twinning is often observed as striations or fine parallel lines on the crystal face. Rutile, aragonite, cerussite, and chrysoberyl often exhibit cyclic twinning, typically in a radiating pattern.
