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.
Best Answer: The mineral group is Hematite Group Formula: M2O3 also known as the Corundum Group. A group of simple, rhombohedral oxides, where M = Al, Fe, V, Cr, Ti. It needs to be understood how minerals are organized first by class, groups, (some subgroups), and last, species. You can not just say oxides because that would be only naming the class that hematite belongs with. Your question asks for which group does hematite belong to. This means that the group that it belongs with is the Hematite Group. Please see the information I have listed along with the sources sighted. Minerals can be organized, mainly according to their chemistry, into the following classes: This a list of CLASSes Consisting of:
