iridescence of such materials as pearl.. Greasy-appearance of being coated w/ oily substance… Silky-sheen of fibrous materials such as silk.. Resinous- example amber. Hardness Refers to "scratchability" or resistance to being scratched. Harder minerals will scratch softer minerals. Geologists rank minerals according to hardness using the Moh’s scale. The following is a listing of the minerals of the Mohs scale and their rating: 1. Talc –softest mineral 6. Orthoclase Feldspar

(Gardiner and Wilcox 107). There are many intriguing physical properties to mineral identification. Visible properties include color‚ luster‚ streak‚ crystal form‚ cleavage. The tactile property can be measured using Mohs scale‚ which measures hardness of minerals compared to common objects. Additional tests can be used; including acid‚ magnetism‚ smell‚ taste‚ and specific gravity. Taking Exhibit A‚ the most obvious physical property would be to observe its color. It is the least reliable

intrusive rocks harden slowly beneath the surface of the earth‚ and often form large mineral crystals within the rock. Granite is a good example of an intrusive rock.Porphyritic intrusive rocks have large crystals embedded in a matrix of smaller crystals. Pegmatite is the only porphyritic rock on the Science Olympiad list.Extrusive rocks harden quickly during a volcanic eruption and are usually smooth-grained. Basalt is the most common form of extrusive rock. |IgneousName |Classification|Description

"colorless". According to Mohs scale of hardness‚ the diamond is a rated a 10 meaning it is the hardest mineral. In the world today diamonds are used two different things‚ jewelry and industrial use. The diamonds that are seen and use the purpose of jewelry are diamonds with color and clarity that will make them appropriate for jewelry. The diamonds that are used for industrial work are mostly used in cutting‚ grinding‚ drilling and polishing practices. The hardness and heat conductivity characteristics
