XRF现场快速勘查与评价方法在老挝NM铜多金属矿区应用研究

Application of XRF field fast survey and evaluation method in laos NM copper polymetalic deposit region

利用XRF在热带雨林特殊景观条件下进行找矿预测,通过误差校正及仪器标定使XRF仪器较好地适合当地的工作条件。对矿区已实施工程进行现场快速测试分析,通过"点—线—面"系统现场测试分析,获取面积性数据,结合地质和地球物理综合特征,进行找矿预测,圈定矿化体并进行资源潜力估算。建立找矿预测指标,进行未知区找矿预测。

Mineral prediction was conducted in a special sight area of tropical rain forest, with XRF method. Error correction and instrument demarcation were used to make XRF instruments fit the local working conditions well. Fast survey and analysis were done to the geological engineering in the mine area. Area data was acquired by systematic real - time survey and analysis through point line - area. Combined with geological and geophysical characteristics, mineral prediction was conducted, the mineralization bodies were delineated and the resource potential was estimated. Mineral prediction criteria were built and prediction in unknown area can be done.
