Kind Of Types Rock

Further destruction of the entangled rocks by water, wind or animals to other places to settle. Crushed rock can be re-deposited sedimentary rock called petrified or sedimentary rocks. Sedimentary rocks or frozen they may change shape due to changes in temperature and pressure. The rock is called metamorphic rocks deform or metamorphic rocks.

To better understand the types of rock note the following description:

1. ROCK FROZEN

Igneous rock is a rock formed from magma solidifies.
Rocks which include the type of igneous rock are:

B.basalt
Basalt is an igneous rock, dark, fine crystal. Slate is formed from cooling lava bubbles containing gas, but the gas has evaporated. The main characteristics of basalt consists of crystals on a very small, gray-green to gray and perforated.

The use of basalt
Basalt is used for various purposes. Usually basalt crushed for use as a building material. Basalt that has been destroyed is used for road base, concrete mix ingredients, railroad ballast, filter stone in the disposal field. Basal also can be cut into thin sheets of basalt cut and sometimes polished for use as floor tiles, building veneer, monuments and other stone objects.

B. pumice
Pumice is formed from cooling magma containing gas bubbles. The main characteristics of pumice is the color to greyish-porous, bubbly, light to be able to float on water. Batua pumice used as abrasive.

C. Glass or Obsidian Stone

Obsidian is formed on the surface of the lava cools quickly. The main characteristics of this stone is shiny like glass and no crystals. Its color varies from black, black with brownish or reddish motifs, there are also speckled white.
Silver jewelry decorated with obsidian
Antiquity obsidian used to make knives, arrowheads, spear, and other weapons. Today, because of its beauty obsidian used in the manufacture of jewelry.

D. Granite stone

Granite formed from cooling magma occurs slowly below the earth's surface. The main characteristics of granite that is her color of white to gray, sometimes consisting of coarse crystals.
Granite kitchen table

Granite has been used for thousands of years. Cut and polished granite rough use in buildings, bridges, paving, monuments and so forth. Indoors, polished granite slabs and molded for use as tiles, stairs and even the table.

2. ROCK SEDIMENT
Sedimentary rocks / sediment formed by igneous rocks are eroded, and then undergo a process of transporting and deposited elsewhere. Sedimentary rocks are distinguished by the type of the transport of substances, namely:

  • Aeolis sedimentary rocks: rocks that the transport by wind
  • Alluvial sedimentary rocks: rocks that transport processes and the formation by the flowing water. Example: delta at the mouth of the river
  • Marine sedimentary rocks: rocks that are formed by the process of transporting and seawater. Example: sand-dune at the beach
  • Glacial sedimentary rocks: rocks that transport processes and formation by glaciers or ice flowing
The types of sedimentary rocks are:
A. Conglomerate
Konlomerat is a type of igneous rock constituent rounded granules.
conglomerate
breccia

B. Breccia
Stone breccia composed of sharp crystal rocks
sandstone

C. Sandstone
Sandstone or sandstone formed from grains of sand carried by the river flow, wind, and waves, and finally collected in one place.

 D. Limestone / limestone
Most of the limestone found in nature occur organically, which is derived from the deposition of shell / and snail shells, foraminifera or algae, or derived from an animal skeleton coral / shells. Limestone can be creamy white, light gray, dark gray, brown and even black, depending on the presence of mineral impurities.
The use of limestone already diverse mix them for building materials, rubber and tire industry, paper, and others.

E. Gypsum
Gypsum usually white, gray, brown, yellow, and transparent. The precipitate gypsum usually found in lakes, oceans, hot springs, and sulfur deposits pathways originating from the volcano.
Gypsum has many uses since prehistoric times to the present. Some uses of gypsum are:

  •      Adhesive.
  •      Filter and as a soil fertilizer
  •      As an addition to the building materials violence
  •      For raw materials of chalk
f. Coal / Coal
  Coal is a fossil fuel, is a combustible sedimentary rock, sedimentary organic, primarily plant debris and formed through a process pembatubaraan.
  Coal is primarily used as a fuel. But today it is increasingly reduced coal use, in addition to a natural resource that can not be renewed, the use of coal also cause pollution.

3. metamorphic rocks (METAMORF)

Bersal metamorphic rocks of igneous and sedimentary rocks are changed due to the influence of high temperature and pressure in the earth's crust.
Various kinds of metamorphic rocks or metamorphic are:

A. Marble or marble stone
marble stone
Marble is limestone that is changed due to high pressure and temperature in the Earth's crust. Marble or alabaster has a shiny surface with a soft color lines cross is widely used as a beautiful decoration stone seen.

Handicrafts from marble
Marble is often used to membut various handicraft items such as tables, ashtrays, jars and various other decorations.

B. Stone Sabak
Slate is a metamorphic rock derived from fine-grained sedimentary rocks, such as shale has changed due to high pressure and temperature.
Antiquity thin slate slabs are used as stationary as a substitute for the book.

C. Quartz Stone
Stone quartz sandstone derived from temperature and pressure changes due to the steeper. Stone quartz crystal prism-shaped hexagon, transparent colors are very diverse. Since ancient times used for the manufacture of quartz glass and ceramics and partly used as gemstones.
