| 摘 要： | 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。 |

| Abstract: | The prediction of the spatial location,shape and mineralization degree of buried ore deposits(orebodies)is a frontier subject and a hot topic of economic geology.An attempt has been made to use the high-resolution shallow-level seismic and magnetotelluric methods,combined with the conventional high-precision gravity,magnetic and induced polarization methods to detect and predict the spatial location,shape and mineralization degree of buried ore-bearing mafic-ultramafic bodies(Cu-Ni deposits)during the prediction and search of the Baishiquan basic-ultrabasic type buried Cu-Ni deposit,eastern Tianshan,Xinjiang.As a result,the deep attitude and shape of the Baishiquan complex are in the main ascertained and five buried low-resistivity anomaly areas were found.Drilling of two of the five anomalies reveals that the results of the prediction by the combined geophysical methods are accuraite and effective and a 28 m thick Cu-Ni orebody is found at the location of anomaly YC-II. |
| Keywords: | buried Cu-Ni deposit location prediction exploration by combined geophysical methods Baishiquan eastern Tianshan |
