Description
Summary:Jacobson discusses the quarry at Montebras, France, highlighting the mineral montebrasite, a lithium aluminum phosphate with an end member composition of LiAl(PO4 )(OH), has an interesting mineralogical history. The history documents the challenges in the late 1800s to measure OH and F in minerals by wet chemical methods as well as Alfred Des Cloizeaux's dedication to ensuring the survival of a mineral species he named after the quarry. The geology of the quarry where montebrasite, numerous other phosphate minerals including the best turquoise in France, ceramic-grade feldspar, cassiterite, and other tin-bearing minerals are found is unusual--a greisen and pegmatite overlying a granitic cupola.
