Gypsum is quite a uniquely versatile mineral, but it is mainly used for industrial purposes, and as a binding agent. In fact, the wordes from the Greek word for plaster. It should be no surprise then, that it is theponent in plaster. It can also be found in blackboard chalk, drywall, and in fertilizer. This mineral is sometimes found in an alternate form called alabaster
Minerals are classified by key chemical constituents the two dominant systems are the Dana classification and the Strunz classification. Silicateprise approximately 90 of the Earth's crust. Other important mineral groups include the native elements, sulfides, oxides, halides, carbonates, sulfates, and phosphates.
Classification 4. Categories. Meaning of Meat: Many people in the context of meat refer to foodes from lamb but in reality, meat is the body tissue of any animal that is eaten as food. This could be meat from chicken, lamb, cow, and even frog legs. In order to classify this broad selection of meats available, the first and foremost approach is to segregate fish from meat. This is
Therefore, it is no surprise that in antiquity, the term precious was attributed to the rarest and most sought after gems at the time. In the 19th century, the terms precious and semi precious became widespread. Precious labeled the shortlist of the most valued gems and semi precious defined the remaining exemplars relevant to jewelry. Currently, gemstones used in jewelry that are not

The details will be debated until the sun cools, but the broad brush classification of mineral deposits is generally understood. Why Do Classification Systems Matter?
Classification of minerals Since the middle of the 19th century, minerals have been classified on the basis of theirposition. Under this scheme, they are divided into classes according to their dominant anion or anionic group e.g., halides, oxides, and sulfides.

Hematite, also spelled as haematite, ismon iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite formplete solid solution at temperatures above 950 °C 1,740 °F.

Classification by the mineral found inside the Geode. On the basis of the mineral found inside the geodes, they can be classified into five main types: Amethyst Geodes: Said to promote peace of mind, amethyst geodes are simply beautiful to look at. These geodes, as indicated by the popular mineral, amethyst. Quartz Geodes: One of the ideal gemstones, quartz, is one of the most abundant
Classes of Minerals Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S2.
Rock classification Igneous Sedimentary Metamorphic. Igneous rocks Igneous rocks form when molten rock magma cools and solidifies, with or without crystallization,either below the surface as intrusive plutonic rocks or on the surface as extrusive volcanic rocks. Texture Texture refers to the physical appearance or character of a rock, such as grain size, shape, and arrangement. Igneous
