Rock Forming Minerals

Sandstone can contain a variety of mineral grains, including quartz, feldspar, lithic fragments, and sometimes mica or clay minerals. Shale: Shale is a sedimentary rock composed primarily of clay minerals, such as kaolinite, illite, and/or montmorillonite. Shale may also contain other minerals like quartz, feldspar, and calcite.

Feldspar vs. Quartz: What's the Difference? 5 Crucial Signs

The most crucial distinction between feldspar and quartz is that feldspar is a group of minerals, whereas quartz is a single mineral. When comparing specific specimens from the feldspar group to quartz, the differences discovered have to do with: Formation; Hardness; Cleavage; Appearance; Gemstone Classification

Identifying Minerals | Geology

Quartz is much harder, hard enough to scratch glass. Calcite is soft, and will not scratch glass. Quartz has no mineral cleavage and fractures the same irregular way glass breaks. Calcite has three cleavage directions which meet at angles other than 90°, so it breaks into solid pieces with perfectly flat, smooth, shiny sides.

3.6: Identifying Minerals

Streak examines the color of a powdered mineral and can be seen when a mineral sample is scratched or scraped on an unglazed porcelain streak plate. A paper page in a field notebook may also be used for the streak of some minerals. Minerals that are harder than the streak plate will not show streak but will scratch the porcelain.

2.1: Minerals

The three main feldspar minerals are orthoclase (a.k.a., potassium feldspar), and two types of plagioclase: albite (sodium only) and anorthite (calcium only). Quartz contains only silica tetrahedra, so only has silicon and oxygen. In quartz the silica tetrahedra are bonded in a "perfect" three-dimensional framework.
