| 摘 要： | 由于土壤地球化学测量查证督冷沟水系沉积物异常效果不理想, 在分析水系沉积物异常产出地质背景、综合异常特征和区域成矿规律的基础上,结合督冷沟铜钴矿含矿岩石与围岩幅频率差异较大,利用物探激电测量对水系沉积物异常进行检查、异常定性,并对物探异常利用工程揭露,发现了多条矿体;同时,利用瞬变电磁方法具有探测深度大、异常响应强的特点,对矿体的延深进行推测,钻探验证了其推测.从而阐述物探方法在青海东昆仑都兰地区异常查证及矿体延深预测的有效性.

| Abstract: | Since the effects of soil geochemistry survey in anomalies verification of stream sediments in the Dulenggou district showed bad results,after analyzing geological background of stream sediment anomalies occurrence,features of comprehensive geochemistry anomalies and regional mineralization regularity,dual frequency induced polarization method had been chosen for anomaly verification as obvious different breadth frequencies between the country rocks and mineralized body. Several mineralizing bodies have been found by engineering testing. At the same time,according to transient electromagnetic method characteristics,ore bodies in depths have been forecasted,and been verified by drilling. These show that geophysical prospecting method was feasible and effective in the Dulanggou district. |
