Excerpt from The Barite Deposits of Missouri and the Geology of the Barite District: A Dissertation Submitted to the Faculty of the Ogden Graduate School of Science, in Candidacy for the Degree of Doctor of Philosophy, Department of Geology Sulphate of Barytes (heavy Spar) - Mine a Burton (potosi), Old Mines, Mine Shibboleth, and numerous other mines in Washington County, Missouri are characterized by sul fate of barytes. In those mines it forms the matrix of the lead ore; though it is sometimes found unaccompanied by ores of any kind, and the quantity which is found at Potosi alone is suffi cient, according to our present ideas of its uses, for the supply of the whole world. It is generally found in compact or tabu lar masses, very white, heavy, and glistening. Sometimes it is crested, columnar, prismatic, or lamellar and frequently the sur face of the crystals are yellow, from an ochery oxide of iron. All the barytes I have observed in Missouri are perfectly opaque. Schoolcraft suggests on page 101 that the barite might be used as a flux. Litton1 in his report on the lead mines of south eastern Missouri mentions the minerals of the following metals as being the only ones that were important: Pb, Fe, Cu, Ni, Co, Zn, and Mn. Apparently the mining of barite had not yet begun at that time. Broadhead2 in a report on Miller County mentions the find ing of barite crystals, and also comments on the use of barite as a pigment, but does not indicate that he was aware of its being mined for that purpose in Missouri. In a later report3 Broad head mentions in considerable detail the use of barite in paints, but fails to state definitely that it was being mined in Missouri.
