THE LONAVALA QUARRY

摘要

Among the most attractive of the Deccan Trap minerals-because of their intense colors-are the vanadium-containing species: green fluorapophyllite, cavansite and pentagonite. The Wagholi quarry complex near Pune has, until recently, been the only area to yield good-quality specimens of the two polymorphic calcium-vanadium silicates: cavansite and pentagonite. In 2003, however, an occurrence of these two minerals was discovered at the Lonavala quarry in the eastern end of the Ghats Range between Bombay and Pune, during The Second Indian Scientific Expedition of The "Spirifer" Geological Society. This quarry was previously very well known for producing top-quality mesolite and attractive green (vanadium-bearing) fluorapophyllite.
