Characteristics of ore-hosted strata and ore-controlling structure of Co-Au mineral deposit in Tuolugou area, Qinghai

The break-through in Co-Au mineral exploration in Tuolugou area,is a major achievement scored in the large-scale land resource survey in recent years. The special orientation of the Co-Au mineral deposit and distribution of its ore body is controlled by the loyal duetile shear zone of Tuolugou-Zhongyangshan.The mineral deposit occurred in the sedimental rock system of sulfide,shows the charactaristic of layer-controlled.Rocks underwent strongly shearing deformation.The mineral deposit type belongs to the sedimentary and transform one.
