Scheelite

Scheelite occurs in contact metamorphic skarns; in high-temperature hydrothermal veins and greisen; less commonly in granite pegmatites. Temperature and pressure of formation is between 200 and 500 °C and from 200 to 1,500 bars. Typical mineral association includes cassiterite, wolframite, topaz, fluorite, apatite, tourmaline, quartz, grossular–andradite, diopside, vesuvianite and tremolite. Scheelite usually occurs in tin-bearing veins; and is sometimes found in association with gold. Fine crys
