【摘要】 苍山地区在寻找鞍山式铁矿和金伯利岩管的地质工作中积累了较多的地质、物探、化探资料。通过资料收集、数据库建立、数据处理和可视化,在贾庄一带新圈定一处1∶5 000磁异常,磁异常位于中生代贾庄闪长岩体与寒武系、奥陶系碳酸盐岩的接触带附近,具有夕卡岩型金铜矿的成矿条件,圈定了找矿靶区。根据成矿条件相似地区探矿经验,推断靶区成矿深度极限为新元古界二青山组底部的不整合面,距地表431~600m。本次地质资料二次开发取得新的成果得益于GIS信息技术应用、现代成矿理论的指导,以及探矿经验的总结。更多还原

【Abstract】 A lot of geological and geophysical &geochemical data for Anshan type iron deposit and kimberlite pipes have been accumulated in Cangshan District.The data are collected and processed and the database built thus visualized.At Jiazhuang village a magnetic anomly at scale 1:5000is delineated about the contact of Jiazhuang diorite body and Cambrian and Ordovician carbonate rock strata.Skarn at the contact is potential for skarn type Au-Cu ore deposit and some targets are circled.According to experience of prospecting in areas with similar metallogenic condition ore of the targets should be hit at 431~600mbeneath the surface at the bottom conformity of Neo-Proterozoic Erqingshan formation.The secondary development of the data is completed by means of GIS data,modern metaloogenic theories and previous ore prospecting experiences.更多还原
