| 摘 要： | 天宇铜镍矿位于干旱戈壁荒漠区。通过对研究区2 km^2范围内1∶1万地气测量,统计分析了地气中Ni、Co、Fe、Mg、Cu等的地球化学特征,研究了各元素对矿化体及物化探异常的指示效果,划分出了5处地气综合异常,得出Ni、Co、Cu、Fe、V地气指标能有效指示矿体位置,对天宇铜镍矿具有较好的找矿效果。该结论为在干旱戈壁荒漠区矿产勘查工作提供了新思路。

| Abstract: | The Tianyu Cu-Ni deposit is located in the Gobi desert area. The geochemical characteristics of elements such as Ni, Co, Fe, Mg and Cu in the geogas were statistically analyzed by geogas survey at the scale of 1∶10 000 in the range of 2 km^2 in the Tianyu Cu-Ni deposit. According to the indication effect of each element on mineralization and geophysical and geochemical anomalies, five comprehensive geochemical anomalies were delineated, and Ni,Co,Cu,Fe,V indicators can effectively indicate the position of the orebody, thus exhibiting good prospecting effect in the Tianyu Cu-Ni deposit. The survey work provides new ideas for mineral exploration in the Gobi desert area. |
