柴达木西北缘牛鼻子梁地区地球化学特征及找矿指导

牛鼻子梁地区位于柴达木盆地西北缘，属于典型的高原荒漠景观，开展大比例尺的地球化学测量，能获取更为真实地球化学信息，大大提高了地球化学信息的收集和地质找矿的效果。通过对牛鼻子梁地区的成矿地质特征及重要地球化学异常特征进行分析研究，发现与成矿密切相关的是晚泥盆世基性-超基性岩，断裂构造有一定的控制作用；地球化学异常中Cr、Co、Ni、La、Au等元素异常特征明显，结合内已有的成矿事实，表明寻找与基性-超基性岩体相关的铜镍矿、与韧性剪切带相关的金矿及稀有稀土矿的潜力较大，建议下一步优先对此类异常区进行详细查证和工程勘查。

Geochemical characteristics and prospecting guidance of Niubiziliang area on the northwestern margin of Qaidam

Niubiziliang area is located in the northwestern margin of the Qaidam Basin and is a typical plateau desert landscape. Large-scale geochemical surveys can be carried out to obtain more real geochemical information, which greatly improves the collection of geochemical information and the effect of geological prospecting. Through the analysis of the geological features of mineralization and important geochemical anomalies in Niubiziliang area, it is discovered that the Late Devonian basic-ultrabasic rocks are closely related to mineralization, and the fault structure has control in the mineralization process; the anomalous features of elements are obvious, such as Cr, Co, Ni, La, Au etc. Combined with existing ore-forming facts, there is high potential for finding copper-nickel ore related to basic-ultrabasic rock, and gold mines associated with the ductile shear zone, and rare and rare earth mineral deposits. It is recommended that the next step is to give priority in these anomaly zones to do detailed verification and engineering survey.
