Located in southeastern Qingtian County, Zhejiang Province, the Qingtian Shankou pyrophyllite deposit is the largest pyrophyllite deposit in China. The ore bed of the deposit is located in acidic lava and volcaniclastic rocks in the middle and upper parts of the second section of the Upper Jurassic Xishantou Group, which formed on the southeastern side of a barren caldera in the Late Jurassic. It is a type of volcanic late gas-hydrothermal alteration replacement (filling) deposit. The major ore components of the deposit are pyrophyllite and quartz followed by corundum, dumortierite (first discovery), albic vermiculite, alnico and other new montmorillonite minerals. The compact and fine stone blocks are called ‘Icy Stone’, and they are good for carving. The deposit has a long history of pyrophyllite mining.
