Both the lowering of the Earth's surface temperature and the evolution of many new types of animals could result from a decrease in atmospheric carbon dioxide and a rise in oxygen caused by the presence on land of lichen fungi and plants at this time, which our research suggests, Hedges says.
Baryte or barite (Ba S O 4) is a mineral consisting of barium sulfate.The baryte group consists of baryte, celestine, anglesite and anhydrite. Baryte is generally white or colorless, and is the main source of barium.Baryte and celestine form a solid solution (Ba,Sr)SO 4.aryte that is used as an aggregate in a heavy cement is crushed and screened to a uniform size. Most baryte is ground to a small, uniform size before it is used as a filler or extender, an addition to industrial products, in the production of barium chemicals or a weighting agent in petroleum well drilling mud.
Barite is a mineral composed of barium sulfate (BaSO 4). It receives its name from the Greek word barys which means heavy..This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral.arite is the primary ore of barium, which is used to make a wide variety of barium compounds. Some of these are used for x-ray shielding. Barite has the ability to block x-ray and gamma-ray emissions.
