Identifying Minerals Pdf Properties. the physical properties of minerals are determined by the atomic structure and crystal chemistry of the minerals. the most common physical properties are crystal form, color, hardness, cleavage, and specific gravity. crystals one of the best ways to identify a mineral is by examining its crystal form (external shape). a crystal is.

Apatite (ca5(po4)3(f,cl,oh)) is a calcium phosphate mineral that occurs as clear, pale green, slender microscopic crystals within plagioclase feldspar, biotite, and chlorite in some of the coarse igneous rock units in the fells, especially the medford dike (fig. 3.33). your teeth are made of a form of apatite. Rock)! many minerals and rocks are the same color, which can make it challenging to identify which is which just by color alone. go into the gem & mineral hall at the natural history museum on level 1 and pick one mineral that catches your eye (or flip to the back of this guide to see a list of common minerals). conduct a scientific observation. Figure 4.6.5 4.6. 5: some minerals have different streaks than their visual color. 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.

Color. color is rarely very useful for identifying a mineral. different minerals may be the same color. real gold, as seen in figure 2, is very similar in color to the pyrite in figure 1. figure 2. this mineral is shiny, very soft, heavy, and gold in color, and is actually gold. the same mineral may also be found in different colors. Mineral identification a mineral is any naturally occurring inorganic solid that possesses an orderly internal structure and a definite chemical composition. a rock is any solid mass of mineral (or mineral like) matter that occurs naturally. the classification of rocks requires the identification of its constituent minerals. minerals may.
