摘要
特斯勒铜锌多金属矿化点位于大兴安岭成矿带中南段,经地质调查发现,矿体产于二叠统大石寨组二段酸性火山岩夹沉积碎屑岩地层中,与晚二叠世花岗闪长岩关系密切,受NE向逆断层控制,地表矿化蚀变明显。通过对1∶5万化探水系沉积物异常进行岩石地球化学查证,发现原生晕异常清晰,并经捡块样分析和探槽工程揭露,发现了明显的矿化,显示该区具有较好的成矿远景。
Tesile copper and zinc polymetallic deposit is located in southern-middle parts of the Da Hinggan Ling metallogenic zone. After geologic survey, it is found that the orebodies, which have closer relationship with granitic diorite of later Permian epoch and are controlled by thrust fault of NE direction, are distributed in acidic volcanic with sedimentary clastic rock formation of the second part of Dashizai Group of Permian se- ries. There is obvious alteration in surface. By means of verification to 1 ：50000 geochemical anomalies of stream sediments in rock geochemical method, some obvious primary halos are found, and through analysis to picking samples and excavate to exploratory trench, some obvious mineralization are found, it shows that the area has good metallogenic prospect.
