All rocks are made of two or more minerals, but minerals are not made of rocks. A mineral is the same all the way through. There are about 3,000 known minerals on Earth. Quartz is one of the most common minerals found on Earth, and basalt is the most common rock. Diamond is the hardest natural substance on Earth, and a diamond is used to cut another diamond. Marble forms from .
Common rockforming minerals There are almost 3000 types of minerals, but only 8 of these minerals make up 90% of the rocks of Earth''s crust. 1. Quartz 12% 2. Potassium Feldspar 12% 3. Plagioclase Feldspar 38% 4. Pyroxene 11% 5. Hornblende/Amphibole 5% 6. Biotite Mica 5% 7. Clays % 8. Olivine 3% 9. Other %
Natural diamond is a mineral composed of a single elementcarbon. Diamondbearing placer deposits . When diamondiferous kimberlite is completely altered and stripped away by meteoric erosion, the constituent minerals released can be transported over considerable distances by rivers and streams before being deposited (Harben and Kuzvart, 1996).

Relates to mineral type oxides, silies= hard, most hydrous minerals soft, very diagnostic often identifiion tables are grouped based on hardness. F Mohs in 1812 chose 10 common mineral to define what I snow called the Mohs relative hardness scale: 1 Talc, 2 Gypsum, 3Calcite, 4 Flourite, 5 Apatite, 6 Orthoclase, 7 Quartz, 8 Topaz, 9 Corundum, 10 Diamond in reality the Mohs hardness is ...
Common minerals include quartz, feldspar, bauxite, cobalt, talc, and pyrite. Some minerals have a different colored streak than the color of their body. A gem is a piece of rare mineral such as diamond, emerald, or sapphire that is cut and polished to shine. Certain minerals are needed by our bodies so we can grow healthy and strong. Activities
· Downeyite crystals are colorless and transparent and have a diamondlike luster. Eastonite. Eastonite is a mineral of the biotite subgroup of mica. Its colors are typically towards the lighter shades of dark mica. Fayalite. Fayalite is an ironrich member of the olivine group with greenishyellow, yellowbrown, brown, or pale yellow to amber colors. Fluorite. Fluorite, also known as Blue .
Talc : diamond: corundum: topaz: quartz: orthoclase: apatite: fluorite: calcite: gypsum: talc: Test. Using moderate pressure, drag a sharp edge over the smooth surface of a mineral. If the surface of the mineral is scratched then it is softer than the material used to scratch it, if not then it is harder. Terminology. Soft can be scratched by a fingernail, Mohs'' 12; Medium can be ...

Minerals and gems are classified by their physical properties, including hardness, luster, color, density, and magnetism. They''re also identified by the ways in which they break, or the type of ...
· A rough diamond. Diamonds are the hardest minerals, with a Mohs scale hardness rating of 10 (Source: USGS [public domain] via Wikimedia Commons). Over 5 400 different minerals have been acknowledged to exist by the International Mineralogical Association (IMA).This international group is responsible for naming minerals and verifying new mineral discoveries.
· Luckily, since diamond is the hardest mineral, it can usually survive such rough handling. This delivery system in the form of volcanic transport only adds to the mystique and value of natural diamond. There are two main magma types that carry natural diamonds to the surface. These magmas crystallize on cooling into volcanic rocks known as kimberlite and lamproite (see box A). Kimberlite is .
Diamond: Difficult to test in the field: Creating a Mineral Hardness Test Kit . A mineral hardness test kit can be easily created from common or hardware items (table 6). Parents should help children make the kit. Wear safety glasses and gloves when cutting class. All pieces in the hardness test kit should be compared to one another and specific minerals with a known hardness ...
· Talc is the softest mineral and diamond is the hardest mineral. Most of the minerals you will encounter will be between 2 and 7. If a mineral can be scratched with a copper penny, but cannot scratch glass, then your mineral has a hardness between 36. Luster. Luster refers to the brightness of light reflected from the mineral''s surface. The main types of luster are metallic and nonmetallic ...
Certain minerals are present in the rocks from the upper mantle that occur with diamonds in kimberlite and lamproite pipes, as seen in nearby cases of xenoliths and diamond inclusions. Some of these minerals, being resistant to weathering and denser than quartz sand, concentrate in channel bottoms. Because they occur in far greater abundance than diamond, exploration geologists look for these ...

Mineral Groups Most minerals are made up of a ion (a positively charged ion) or several ions and an anion (a negatively charged ion (, S 2–)) or an anion complex (, SO 4 2–). For example, in the mineral hematite (Fe 2 O 3), the ion is Fe 3 + (iron) and the anion is O 2– (oxygen). We group minerals into classes on the basis of their predominant anion or anion group.
