| 中文摘要: |
| 金矿化作用伴随围岩蚀变,且多受断裂控制,反映在地球化学上出现某些元素的异常。在已发现一定矿（化）作并掌握一般控矿特征的地区,利用已有工程在蚀变带内连续拉块采样,分析有关指示元素,总结有关的地球化学指标,建立地球化学预测模式,对已知矿（化）体及外围异常进行地球化学评价。该方法在秦岭南坡金龙山微细浸染型金矿上的应用有较好的效果。 |
| 英文摘要: |
| Gold mineralization usually accmpanies with wall-rock alteration and is mostly controlled byfaults or fractures. It reflects some elements’ anomalies in geochemistry. In a area where certaingold mineralzation bodies or gold ore bodies has been found and the general ore-controling fea-tures of have been recognized, geochemists can collect composite samples scientifically, mainlymineralization alteraton zone, analyse indicator elements, summarize geochemical indexes, set upthe model of geochemical metallogenic ’prognosis based on the nature of elements’ anomalies orlinear productivity, the gcochemical indexes or elements’ ratios, the estimated values of gradualregression equations, and forecast the deep of known mineralization bodies or ore bodies, and e-valuate the prospects of peripheral anomalies. The method is successful at Jinlongshan gold de-posit which is a sediment-hosted micro-find disseminated type gold deposit in Qingling Mountain. |
