| 摘 要： | 大青山地区出露地层主要是侏罗系中统兰旗组安山岩、安山质角砾熔岩、凝灰岩等;侵入岩为晚侏罗世二长花岗岩;断裂发育,岩石蚀变强烈。金地球化学特征表明,金主要富集在侏罗系中统兰旗组火山岩中。金的原生晕、次生晕异常特征和分布表明,破碎蚀变岩带就是金矿化蚀变带。通过野外地质调查已在三道盘—马家窝铺的安山岩和二长花岗岩中发现了5条金矿化带和29条金银矿脉。实践证明,在大青山地区进行金矿普查运用地球化学方法是有效的。

| Abstract: | The strata occured in Daqingshan area mainly are Lanqi Formation of the middle Jurassic System, the rocks are andesite,andesitic breccia lava, tuff and so on; the intrusive rock is admellite of the late Jurassic epoch, with developed faults and strong alternation.The geochemical characters of gold show that the gold element mainly concentrate in the volcanic rocks of Lanqi Formation of the Jurassic System; and the anomaly characters and distribution of the primary and secondary halos in gold show that the broken altered zones arc the mineralized zones of gold. On the field geologic surveying,five gold mineralized zones and twenty-nine gold and silver ore veins are found in andesite and admellite of Sandaopan-Majiawopu. The practice tells that it is effective for prospecting gold deposits in Daqingshan area on the geochemical method. |
