1.8" Colorful Cubic Fluorite Crystal with Phantoms - Yaogangxian Mine

This is a beautiful fluorite crystal with blue, green, and white phantoms. It was collected from the Yaogangxian Mine in the Hunan Province of China. Under short-wave ultraviolet light, the crystal exhibits a vibrant purple fluorescence.

This specimen has been mounted to an acrylic display base with mineral tack.

The Yaogangxian mine is a tungsten-tin deposit in the Nanling Mountains of Hunan, China. The mine field is about 4 x 2.5 km (2.5 x 1.5 miles) and includes two primary deposits; the Yaogangxian quartz vein-type, tungsten-tin deposit and the Heshangtan skarn-type, tungsten-tin deposit.

The Yaogangxian quartz vein-type, tungsten-tin deposit (with minor greisen-style mineralization) has been mine since 1914 and hosts minor copper, tungsten, silver, lead, zinc and bismuth minerals. The Heshangtan skarn-type, tungsten-tin deposit has been mined since the 1960's and hosts a variety of associated silver ores. Both of these deposits are a result of the Mesozoic Yaogangxian pluton (composed of biotite-granite, porphyritic granite and quartz porphyry) which intruded into Cambrian-Devonian sediments and Jurassic limestones.

A variety of high quality mineral specimens are collected from this site. Some of the most popular minerals include arsenopyrite, bismuthinite, manganese-bearing calcite (manganocalcite), chalcopyrite, ferberite, fluorite, hübnerite, molybdenite, pyrite, rhodochrosite, siderite, stibnite, topaz and tungstite.
