(1) The mountain is one of the most important deposits of barite, a barium bearing mineral that exhibits more gravity than any other mineral with no metallic constituent elements with the exception of uraninite .(2) For example, the presence of pyrite and uraninite can be explained if the atmosphere and surface waters 2.7 billion years ago contained little or no oxygen, a possibility that is supported by several lines of evidence.(3) Arsenopyrite, cassiterite, molybdenite, wolframite, uraninite , and several of the common sulfides have all been observed at various locations.(4) It converts uranium dissolved in water to uraninite , which is much less soluble; this ‘reduction’ process creates small charges of electricity.(5) At Azegour, Morocco, uraninite occurs in tactite with molybdenite, chalcopyrite, barite, pyrite, hematite, and garnet.(6) A comprehensive discussion of the mineralogy and occurrence of uraninite has been given by Frondel, to which the reader is strongly referred.(7) Early investigators recognized bitumen (referred to then as carbon) as having a strong spatial relationship with gold, uraninite and pyrite.(8) Unusual specimens consisting of massive silver associated with uraninite and a variety of cobalt and nickel arsenides were available at one time from mines in the Great Bear Lake region, Northwest Territories.(9) Other accessory minerals are apatite, zircon, monazite, huttonite and rare xenotime, uraninite and betafite.(10) Using this as a standard he acquired a sample of Norwegian uraninite , had this converted to lead tetramethyl, and then measured the abundance of radiogenic lead.
