辽宁排山楼金矿构造叠加晕研究及深部预测

排山搂金矿是绿岩带韧性剪切带中的一个大型金矿床,具有2期3阶段成矿叠加的特点。结合生产实际需要,采用构造叠加晕新方法,通过对排山楼金矿地质、地球化学的综合研究发现:矿体前缘晕特征指示元素是As,Ba,Sb;矿体晕指示元素是Pb,Au,Ag,Cu,Zn;尾晕指示元素是V,Bi,Mo,Co,Mn,Ti,W。结合地质-地球化学时空演化特点,建立了排山楼金矿盲矿预测的构造叠加模型,并总结出排山楼金矿盲矿预测的地质标志和构造叠加晕标志。利用此构造叠加晕模型和地质-构造叠加晕标志成功地预测了排山楼金矿东西向矿体深部的盲矿体。

Structural Superimposed Halo Study and Deep Prediction of Liaoning Paishanlou Gold Deposit

Paishanlou gold deposit is a large scale gold deposit located in ductile shear zone of greenstone area,with a feature of two three-stage mineralization superimposed. Considering the actual demands in production,a comprehensive geological and geochemical study on Paishanlou gold deposit is carried out by the new method of structural superimposed halo. It is shown that the front halo indicator elements of ore-body are As,Ba,Sb; The ore halo indicator elements are Pb,Au,Ag,Cu,Zn; Rear halo indicator elements are V,Bi,Mo,Co,Mn,Ti,W. Considering the geological-geochemical characteristics of temporal and spatial evolution,a structural superimposed halo model is established for predicting blind ore-bodies of Paishanlou gold deposit. And the geological sign and the structural superimposed halo signs of predicting the blind ore-bodies in Paishanlou gold deposit were summarized. Using the structural superimposed halo model and geological-structural superimposed halo signs,the east-west blind ore-bodies in Paishanlou deep deposit are successfully predicted.
