| 中文摘要: |
| 本文通过对大水金矿68、84勘查线8个钻孔岩心进行系统采样和分析,运用改进后的格里戈良法对其原生晕特征进行了研究,认为钻孔中原生晕轴向分带序列均具有明显的“反分带”现象,部分钻孔的底部前缘晕发育,表明大水金矿具有多期叠加成矿特征,并指示深部具有良好的找矿前景。 |
| 英文摘要: |
| In this work the eight borehole cores of the lines of exploration section (No. 68 and 84) in the Dashui Gold Mine were systematically sampled and analyzed, and the characteristics of the original halo were studied by the improved Gerry’s Method. The results show that the original halo axial zoning sequence in the borehole had obvious “reverse zoning” phenomenon, and the bottom of some boreholes developed the front halo, indicating that the Dashui gold deposit has mulita-period superimposed mineralization characteristics and good prospecting potential in the deep. |
