胶西北大金埠晶质石墨矿地质特征及找矿标志研究OA
Geological Characteristics and Prospecting Indicator of the Crystalline Graghite in Dajinbu Area,Jiaoxibei
大金埠晶质石墨矿床位于胶西北Au-Fe-Mo—石墨—滑石—菱镁矿成矿亚带南墅石墨—Au成矿区的西南缘.区内石墨矿化带2条,石墨矿体20个,主要赋矿层位为古元古代荆山群陡崖组徐村段,矿床成因类型为区域变质型.陡崖组徐村段含石墨黑云斜长片麻岩等含石墨变质岩系是直接的地层、岩性找矿标志;区域性褶皱构造的翼部、次级褶皱构造的核部及转折端是重要的构造找矿标志;高极化率、低电阻率激电异常是明显的地球物理找矿标志.
The Dajinbu crystalline graphite deposit is located on the southwestern margin of the Nanshu graphite metallogenic district within the Jiaoxibei Au-Fe-Mo-graphite-talc-magnesite metallogenic sub-belt.The area contains two graphite mineralization zones and twenty graphite ore bodies,primarily hosted in the Xucun Member of the Douya Formation within the Paleoproterozoic Jingshan Group.The genetic type of this ore deposit is classified as regional metamorphic type.Key exploration indicators include:Direct stratigraphic and lithological indicators:Graphite-bearing metamorphic rock series,exemplified by graphite-bearing biotite plagioclase gneiss,of the Xucun Member of the Douya Formation;Critical structural indicators:Limbs of regional folds,Cores and hinge zones of folds within secondary fold structures;Distinct Geophysical indicators:IP anomalies characterized by high chargeability and low resistivity.
