                              MINERALS  Andalusite   Andalusite is an aluminium nesosilicate mineral with the chemical formula Al₂SiO₅. Andalusite is trimorphic with kyanite and sillimanite, being the lower pressure mid temperature polymorph. Anhydrite   Anhydrite is a mineral—anhydrous calcium sulfate, CaSO₄. It is in the orthorhombic crystal system, with three directions of perfect cleavage parallel to the three planes of symmetry   Apatite   Apatite is a group of phosphate minerals, usually referring to hydroxylapatite, fluorapatite and chlorapatite, with high concentrations of OH−, F− and Cl− ions, respectively, in the crystal Arsenopyrite   Arsenopyrite is an iron arsenic sulfide. It is a hard metallic, opaque, steel grey to silver white mineral with a relatively high specific gravity of 6.1. When dissolved in nitric acid, it releases elemental sulf...

Geological time, relative dating and radiometric dating

Image
  age of earth t  the  age of the Earth  is approximately 4.54 ± 0.05 billion  years  (4.54 × 10 9  years ± 1%). This dating is based on evidence from radiometric- age dating   of meteorite    material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples Geological processes Geological processes are dynamic processes at work in the earth's landforms and surfaces. The mechanisms involved,  weathering ,  erosion , and  plate tectonics , combine processes that are in some respects destructive and in others constructive. relative dates based on cross-cutting relationship s Cross - cutting relationships   is a principle of geology that states that the geologic feature which  cuts   another is the younger of the two features. It is a relative dating technique in geology. There are several basic types of cross cutting relationships: Structural rel...

Origin, composition and internal structure of the earth

process of the  formation of the solar system Solar system formed about 4.6 billion year ago, when gravity pulled together low-density cloud of  interstellar  gas and dust (called a nebula)(movie). The Orion Nebula, an  interstellar cloud in which star systems and possibly planets are forming. Solar System Formation. Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a  nearby  star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust. Earth Differentiation .  After the initial formation of protoplanets, remaining gas and dust was gradually blown away by the solar wind during the  heat -up phase of the young sun. At that time our  earth was probably a barren planet, pockmarked by meteorite bombardment, and may have looked on the surface like the Moon.   composition and characteristics of the core, mant...
