rock
rock is a hard thing you have to get it so cool all day.A rock is a solid, stony mass composed.
minerale
Die Liste der Minerale ist eine alphabetisch geordnete Übersicht von Mineralen, Synonymen und bergmännischen Bezeichnungen. Ebenfalls aufgeführt werde
rock:igneous
the Latin word igneus meaning of fire, from ignis meaning fire) forms through the cooling and solidification of magma or lava. This magma can be derived from partial melts of pre-existing rocks in either a planet's mantle or crust. Typically, the melting of rocks is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition.
rock:Obsidian
a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth.
rock:diorite
Diorite is the name used for a group of coarse-grained igneous rocks with a composition between that of granite and basalt. It usually occurs as large intrusions, dikes, and sills within continental crust. These often form above a convergent plate boundary where an oceanic plate subducts beneath a continental plate.
rock:coal
Coal is an organic sedimentary rock that forms from the accumulation and preservation of plant materials, usually in a swamp environment. Coal is a combustible rock and along with oil and natural gas it is one of the three most important fossil fuels.
rock:basalt
Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro. The difference between basalt and gabbro is that basalt is a fine-grained rock while gabbro is a coarse-grained rock.
Rock:tuff
Tuff is an igneous rock that forms from the products of anexplosive volcanic eruption. In these eruptions the volcano blastsrock, ash, magma and other materials from its vent. This ejecta travels through the air and falls back to Earth in the area surrounding the volcano. If the ejected material is compacted and cemented into a rock that rock will be called "tuff".
Rock:siltstone
Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt and the silt is then compacted and cemented into a rock.
Rock:slate
Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. It is popular for a wide variety of uses such as roofing, flooring and flagging because of its durability and attractive appearance.
Rock:flint
Flint is a hard, tough chemical or biochemical sedimentary rock that breaks with a conchoidal fracture. It is a form of mic rocrystalline quartz that is typically called “chert ” by geologists.
Rock:iron ore
Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe2O3) andmagnetite (Fe3O4). These iron ores have been mined to produce almost every iron and steel object that we use today - from paper clips to automobiles to the steel beams in skyscrapers.
What is the different to the rock
Minerale:zoisite
first known as saualpite, after its type locality, is a calcium aluminium hydroxy sorosilicate belonging to the epidote group of minerals. Its chemical formula.
Minerale:gold
Gold is one of the most popular and well-known minerals, known for its value and special properties since the earliest of time. Most of the natural Gold specimens that have been found since early times have been smelted for production.
Minerale:datolite
Datolite forms in very attractive crystals that can be highly lustrous and very sparkly, or have frosted crystal faces.
Minerale:analcime
The aluminosilicate framework of the crystal structure does not change in topology at all. The reduction to various lower symmetries occurs because of slight changes in the ordering of Si and Al atoms and slight crumpling of the framework. Macroscopically, the crystals always look pseudocubic, apart from the very slight nonzero birefringence and fine lamellar twinning visible in the polarising microscope, because the ordering and crumpling happens in different directions in different lamellae, and over the whole crystal it averages out.
Minerale:
biethstone
June counts three gems as birthstones, pearl,Alexandrite, and moonstone. Pearl. Historically, pearls have been used as an adornment for centuries. They were one of the favorite gem materials of the Roman Empire; later in Tudor England, the 1500s were known as the pearl age.
