隐伏矿床(体)空间位置、形态和矿化强度的预测是经济地质学的前沿课题和热点问题。在新疆东天山白石泉基性-超基性岩型隐伏铜镍矿预测与找矿研究过程,尝试性引入高分辨率的浅层地震与大地电磁测深(MT)方法,并结合常规的高精度重力、磁法和激电,开展隐伏含矿岩体(铜镍矿)空间分布位置、形态和矿化强度的联合探查与定位预测。基本查明了白石泉杂岩体的深部产状与形态结构,发现了5个隐伏低阻异常区。对其中两个低阻异常区的钻探结果表明预测结果是准确的,在异常YC-II位置发现了厚28m的铜镍矿体。
The prediction of the spatial location, shape and mineralization intensity of the hidden deposit (body) is a frontier topic and a hot issue in economic geology. In the course of the prediction and prospecting process of the Baishiquan base-ultrabasic rock concealed copper-nickel deposit in the East Tianshan, Xinjiang, a high-resolution shallow seismic and terrestrial electromagnetic sounding (MT) method is tentatively introduced. Combined with the conventional high Accurate gravimetric, magnetic and electrical stimulation are used to carry out joint exploration and location prediction of the spatial distribution location, morphology and mineralization intensity of the concealed ore-bearing rock mass (copper-nickel ore). The basic occurrence and morphology of the Baishuquan complex have been basically ascertained, and five hidden low resistivity anomalies have been found. The drilling results of two low-resistivity anomalous zones indicate that the prediction results are accurate. A copper-nickel ore body of 28 m in thickness was found at the site of abnormal YC-II.
