Shandong Linglong Deposit Geological And Geochemical Modeling And Quantitative Prediction

Jiaodong region is the most important gold mining area of China.Zhaoyuan-Yexian metallogenic belt in the territory of Zhaoyuan and Yexian County has the largest gold reserves of the four metallogenic belts in Jiaodong region.Linglong gold mine is located in Linglong-Jiuqu ore field of the northwestern Jiaodong,it is a typical lode gold mine.Lode gold mine,the Jiaojia-fracture zone altered rock type gold,and Lingshan gold are the main types of gold deposits in Zhaoyuan-Yexian metallogenic belt.Research and the establishment of Geochemical model of the Linglong typical gold deposit is representative and available for China's gold mine deep prospecting lea.It contributes to the quantitative prediction of the Jiaodong gold resources and China's gold mineral resource potential forecast.In this paper,on the basis of the collection of Linglong gold deposit data of geological,Regional rock,the primary halo,regional geochemical,I studied the geological characteristics,characteristics of geochemical anomalies,and built the geological-geochemical prospecting model of Linglong gold.I also did quantitative prediction of Linglong gold and typical gold deposits in northwestern Jiaodong.Mainly the following conclusions:Linglong Mine significantly enriched in Au,Pb,Mo,Sr,Ba,light rare earth elements and F,Ni,Cr,etc,compared with the average content of the eastern continental crust elements,and their enrichment factors are all greater than 1.24;The deposit primary halo significantly enriched in Au,Ag,As,Sb,Pb,Zn,Cd,W,Sn,Bi,B,Rb,etc,compared with the content of Regional rock,and their enrichment factors are all greater than 1.5:The indicator elements of regional geochemical exploration are Au,Ag,As,Pb,Zn,Cd,Cu,Bi.Cause the coincidence degrees between the abnormal and mine are high.and the enrichment factors of Au,Ag,Pb are all greater than 1.26,compared with the stream sediment average even the enrichment factor of Au is 26.8;In the case of guaranteeing a certain number of samples,abnormal scale considering abnormal scale is not influenced by anomaly thresholds.Linear empirical equation between reserve and abnormal scale:Y=0.010x(1-F)+61.76.(Y-Reserve;x-Abnormal scale;F-Erosion coefficient),and this equation is better than analogism.By linear empirical equation between reserve and abnormal scale,the reserve of northwestern Jiaodong gold mines is about 604.33t,estimating the depth of 500m.
