甘肃北山红柳沟铜镍矿地球化学特征及成矿潜力

Geochemical characteristics and metallogenic potential of the Hong Liu Gou Cu Ni deposit, Beishan, Gansu

甘肃北山是我国西北地区最重要的铜镍矿成矿区带之一,红柳沟岩体为北山地区近些年发现的矿化基性-超基性杂岩体。岩体两侧分别处在大山头—岗流脑子、方山口—庙庙井—双鹰山两条区域性深大断裂带。通过对红柳沟岩体地球化学特征的分析研究,认为具有一定的成矿潜力。

Beishan,Gansu Province is one of the most important copper-nickel metallogenic belts in Northwest China.The Hongliugou intrusion is a mineralized BASIC-ULTRABASIC complex discovered in Beishan area in recent years.The two sides of the rock mass are located in two regional deep fault zones:Dashantou-Gangliuonaozi and Fangshankou-Miaomiaojing-Shuangyingshan.Based on the analysis of geochemical characteristics of the rock body of the red willow gully,it is considered that there is a certain metallogenic potential.
