Feldspars (KAlSi 3 O 8 – NaAlSi 3 O 8 – CaAl2Si 2 O 8)are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.. Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a …

Metamorphic rocks are the result of pressure and heat applied to igneous or sedimentary rocks. The appearance of these rocks is transformed along with the structure; for example, metamorphic sedimentary rocks retain the layers, but the layers are bent and compressed. Some examples of metamorphic rock include marble, slate and gneiss.

Squadra Archivi BMR. Squadra represents the success of BMR in the field of wet squaring technology. With the Squadra machine, BMR moved away from the traditional solutions provided by the marble and natural stone industry and introduced the use of upper pressure belts (Syncrobelt) that marked an era that is still considered relevant.

Metamorphic rocks are often formed by processes deep within the Earth that produce new minerals, textures, and crystal structures. The recrystallization that takes place does so essentially in the solid state, rather than by complete remelting, and can be aided by ductile deformation and the presence of interstitial fluids such as water.

Feldspar - Wikipedia. Feldspathic refers to materials that contain feldspar. The alternate spelling, felspar, has fallen out of use. The term 'felsic', meaning light colored minerals such as quartz and feldspars, is an acronymic word derived from feldspar and silica, unrelated to the redundant spelling 'felspar'.

Igneous rocks such as granite or lava are tough, frozen melts with little texture or layering.Rocks like these contain mostly black, white and/or gray minerals. Sedimentary rocks such as limestone or shale are hardened sediment with sandy or clay-like layers (strata).They are usually brown to gray in color and may have fossils and water or wind marks.

The sedimentary rocks are formed by diagenesis or lithification of sediments, which in turn are formed by the weathering, transport, and deposition of existing rocks. The scientific study of rocks is called petrology, which is an essential component of geology.

This rock-forming process may occur underground at depth, in which case the product is an intrusive (or plutonic) igneous rock, such as granite or gabbro. If magma reaches the Earth’s surface and then solidifies, it forms extrusive (or volcanic) igneous rock, such as rhyolite or basalt.
