贺兰山北段地区地球化学特征及找矿前景分析

通过总结区域地质背景、地球化学异常特征、异常查证成果,并结合前人研究成果的基础上,分析该区蚀变岩型金铜矿、岩浆型金钨矿、岩浆型铜镍矿、岩浆型稀有稀土矿及沉积型铁矿的成矿地质条件,提出了贺兰山地区今后在金、铜、镍、钨等矿种的找矿方向和建议。

Geochemical characteristics and prospecting prospect of the northern part of Helan Mountain

Based on the regional geologic background,geochemical anomaly characteristics and anomaly verifi-cation results,and combined with achievements of previous works,this paper analyzed the metallogenic con-ditions of altered rock type Au-Cu deposits,magmatic Au-W deposits,magmatic Cu-Ni deposits,magmatic rare earth deposits and sedimentary Fe deposits in this area.It also put forward the prospecting direction of minerals like Au,Cu,Ni and W in Helan Mountain and offered some suggestions on prospection.
