Apr 10, 2010· Quartz, feldspar and mica are some of the most abundant minerals in the earth's crust. Quartz (SiO2) is present in almost all rocks. It is hard, resistant to chemical weathering and has no cleavage, which means it is also resistant to physical weathering.
The QUARTZ Corp's mica products occur in the same area as our quartz products, and offer a number of unique properties including being chemically inert, dielectric, elastic, flexible, hydrophilic, insulating, lightweight, platy, reflective, refractive, and extremely resilient. Mica can be treated to occur in a range of opacities, from fully opaque to transparent.

Plagioclase feldspar is a compound of sodium and silica; potassic feldspar is a compound of potassium and silica. Granite also contains quartz, the second most abundant rock-forming mineral after feldspar. The fourth main mineral compound is mica, which in granite is a silica compound with a crystalline appearance resembling sheets of paper.

Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties. Minerals that could be used to replace feldspar include pyrophyllite, clays, talc, and feldspar-silica (quartz) mixtures. The abundance of feldspar will make these substitutions unnecessary for .
Rocks make up the majority of the Earth's crust. One of the most common rock is granite. The four minerals that make up granite are feldspar, quartz, mica, and hornblende. Granite was formed when magma cooled slowly forming crystals of the four minerals that make up the rock granite. Look at the photo above of granite.

In others single crystals of nearly pure feldspar may be 20 feet across, and single beryl crystals may reach the diameter of a hogshead. The major part of the pegmatites are nearer the lower limit of coarseness than the higher. Only the coarser bodies are commercially valuable for their feldspar, quartz, mica, or gem minerals, and these constitute
quartz and feldspars have interference colors in shades of gray to white, and others like hornblende and mica have a wide range of bright interference colors. The two types of photos are shown side by side to help show the mineralogy and textures that are not easily seen in only one or the other alone. Mineral color identification is
Granite is a coarse-grained, light-colored igneous rock composed mainly of feldspars and quartz with minor amounts of mica and amphibole minerals. This simple definition enables students to easily identify the rock based upon a visual inspection.
