甘肃省南部矿集区水系沉积物测量地球化学特征及找矿预测

通过在甘肃南部矿集区开展1∶5万水系沉积物测量,获得了较为丰富的地球化学资料。对元素的含量特征、分布特征、组合特征、异常特征等要素研究发现,该区各元素的背景值均高于高寒山区的平均值,且Au、As、Sb、Hg等元素异常分布明显,富集程度高,具有一定的找矿潜力。结合地质背景和已知矿床特征,根据异常分布特征优选出6处找矿靶区,其中A(2)找矿远景区为寻找Au矿的有利部位。

Geochemical Characteristics of Stream Sediments and Metallogenic Prognosis of Southern Ore-concentration area, Gansu Province

Access to a wealth of geochemical data by conducting the 1:50000 stream sediment survey in the Southern Ore-concentration area of Gansu Province. The content of the feature element, distribution characteristics, a combination of features, anomalies and other factors found that the area of each element background values are higher than the average of alpine mountains, and Au, As, Sb, Hg and other elements significantly abnormal distribution, rich set high degree, with some prospecting potential. Combined with the geological background and characteristics of known deposits, according to the abnormal distribution of the optimized six prospecting targets, where A (2) prospecting areas looking for Au ore favorable position.
