Skarn-type polymetallic (iron, tungsten, tin) deposit, occurring in the contact zone between Carboniferous and Permian limestones and a Jurassic granite stock, which also hosts separate niobium-tantalum ore bodies.
The iron skarn was discovered during an exploration campaign carried out between 1959 and 1964, but the full potential of the deposit was initially not recognized since prospection had been focused on pyrite ores only. During a field study on granite geology carried out in the area between 1969 and 1971, niobium-tantalum ore bodies were discovered in the weathering crust of the granite, and recent exploration drilling in the mine area intersected economic skarn-type tungsten-tin mineralization. A comprehensive multi-element prospection of the deposit area is still lacking, though (Lei et al., 2009).
