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.
21 Feb, 2013 Who discovered 0. Barium is a soft, highly reactive, silvery metal that is never found in its free form in nature. Barium is a chemical element represented by the symbol Ba and the atomic number 56.he first to correctly identify barium as a new element was Carl Wilhelm Scheele in 1774. He was the first to conclude that a new element was present in the mineral barite. He was unable to isolate the element, but did manage to isolate barium oxide. This was also isolated by Johan Gottlieb Gahn two years later.
