Determination of Multifarious Genesis and Prospecting of Polymetallic Metallogenic Deposit in Hutouya, Qinghai

Qimantag metallogenic belt is very important copper-polymetallic metallogenic beltin Qinghai.Copper-lead-zinc deposits in the Hutouya area composed of Hutouya and Yingqinggou deposit.The deposit prospecting has made great progress in recent years,but the genetic types of deposits remains controversial.Through detailed field observations,we collected evidence from different angles,and then determined two genetic types for the deposits:one belongs to hydrothermal deposit related to Triassic bodies,Tanjianshan group in Ordovician to Silurian,and Di'ao Formation in Late Carboniferous;the other related to Mesoproterozoic Langyashan Formation belongs to SEDEX-hydrothermal superimposition-transformation deposit.At the same time,ore-controlling factors were analyzed and prospecting criteria was established to guide the exploration.
