The natural mineral is a solid that is composed of one or more of the atoms of the chemical element, kapesberg and which is characteristic of the chemical composition and the crystalline structure is, the internal construction. Minerals may be present as elemental phosphorus (e.g., pure gold), as well as more complex chemical compounds (for example, stones day may contain aluminum, kapesberg silicon and oxygen, besides sodium, potassium, calcium, and other chemical elements).
99% of the minerals present in the earth's crust has been formed from eight basic chemical elements (O, Si, Al, Fe, Ca, Na, K, Mg) in different combinations. All other elements make up the remaining tiny part.
Minerals make up rocks. Rocks and minerals difference lies in the fact that the mineral has a specific chemical composition and structure of the compound, but the rock is a set of one or more of a mineral, having a fixed structure, kapesberg and in most cases there is no certainty the amount of minerals of which the composition may vary in a rather wide limits.
The world has known more than 4100 minerals, but only about a hundred of them are widespread in nature. The others are either rare, such as the beautiful light green base gaspeiit known as a stone, or even extremely kapesberg rare, like the other precious gemstone painiit what is currently taking kapesberg the world know just eighteen songs.
The most common mineral is quartz cortex (SiO2), which accounts for almost 12% of all minerals found in the earth's crust. Quartz widespread reason lies in its chemical composition. Namely, the quartz crystal built up of oxygen and silicon atoms, which are the two most common chemical element on the planet Earth. Therefore, quartz can be found to a greater or lesser extent, in almost kapesberg all of the rock in the composition. Other very common rock forming minerals are the days of the rocks, olivine, pyroxene, AMFI boolid, calcite, dolomite, various mica, clay minerals, kapesberg pyrite hematiitja.
Minerals occur naturally in different environments and a wide variety kapesberg of geological protesside effect. The main of them is given below. It should however be borne in mind that, in fact, is a rock formation processes are quite complex, and the picture is not as simple as described here. In addition, a number of minerals, such as quartz, for example, occur in each of the processes described below.
With the advent of magmatic minerals are formed by the slow cooling of a hot melt and solidification. Generally, this process takes place in the depths of the earth's crust tens of kilometers, and can last for hundreds, even thousands of years. Occasionally it happens that magma closer to the surface through the thick kivimkihtide laavana kapesberg volcanoes and can run directly on the ground or blow. In this case the cooling, the formation of minerals in the rock formation directly in our eyes. With the advent of the magmatic minerals such as pyroxene, quartz, apatite, ilmenite, magnetite, olivine, fluorescent rocks, rutile, zircon, tourmaline, mica and many others. These minerals form a magmatic rocks such as granite. Igneous rocks form the main part of the Earth's crust, and is often covered with sedimentary rocks.
Hydrothermal minerals from the earth is a candy-based heat source (such as the melt furnace) by a heated (400 C), aqueous solutions or gases. kapesberg For example, with the advent of hydrothermal barite, dolomite, calcite, chalcedony, quartz, opal, pyrite, sphalerite and others. With the advent of hydrothermal minerals associated with, for example, hot springs and geisritega. kapesberg
Settelisteks mineralization is considered as the waters north of the settled material generated minerals. Sedimentary minerals kapesberg forming in some places reaching several tens of kilometers kapesberg of sedimentary kapesberg lasundeid. Major sedimentary rock is limestone, the Estonian national, as well as various sandstones and clays. Settematerjaliks maybe others crumbled rubble of rocks and minerals, as well as the minerals dissolved in water or in aquatic animals, algae and mineral parts of the body. Sedimentation of minerals dissolved in the water of different chemical reactions take place in the stomach. In this way, emerged as calcite and dolomite limestone, as well as halite, gypsum, etc. limoniit.
Biogenic minerals occur as a result of the life processes kapesberg of organisms. The most important mineral producers are bacteria, lime, silicon and phosphatic skeleton of calcite algae prefer loomakesed building material, such as corals, kapesberg snails, clams, etc.. For example markassiit pyrite is often associated with bacterial activity. Also, quartz, opal, Vivianite and sulfur may be the result of biogenic processes.
Secondary minerals occur near the surface decomposition of primary minerals or their distortion effect deep in the crust. At ground level, for example, is secondary to murendmineraalid anglesiit, hüdrogötiit, goethite, illite, kaolinite, gypsum, chlorite, malachite. Sometimes you get into the ground
