中文摘要:
      察汗森矿区位于青海省欧龙布鲁克陆块边缘,出露地层为古元古界达肯大板岩群地层,成矿地质构造条件优越。通过对该地区成矿地质特征、成矿构造环境、地球化学特征、矿石特征及矿化分布规律进行研究与分析,认为混合岩化热液与碳酸岩接触交代是成矿的主要原因,矿化与矽卡岩化关系密切。初步总结了该区成矿模式,认为该区具有形成与混合岩化有关的矽卡岩型白钨矿的有利条件,为该区下一步矿产勘查工作指明了方向。
英文摘要:
      The Chahansen mining area is located on the edge of the Aulongbrook Block in Qinghai Province. The outcrop stratum is the Dakendaban Gr the Paleoproterozoic strata with excellent metallogenic geological conditions. Through the geological characteristics,structural environment,geochemical characteristics,ore characteristics and mineralization distribution to Conducted a comprehensive study and analysisin this area,it is believed that the contact of metahydration hydrothermal fluid with carbonate rocks is the main cause of mineralization,mineralization Closely related to skarnification. Preliminary summary of the metallogenic model in the area,and it is considered that the area has favorable conditions for forming skarn type scheelite with the migmatization and has pointed out the direction for the next mineral exploration work.
