有机烃气法在个旧锡矿松树脚矿田中的应用

THE APPLICATION OF ORGANIC HYDROCARBON GAS TECHNIQUE TO THE SONGSHUJIAO OREFIELD IN THE GEJIU TIN MINE, YUNNAN PROVINCE

各类岩体、矿石、围岩、地表土壤的烃气测量结果表明 ,个旧锡矿的成矿存在有机物的参与 ,矿体周围存在烃气晕圈异常场 ,已知矿体上方地表有良好的烃气异常反映。认为有机质对金属元素的沉淀、成岩、活化迁移和成矿作用可能比通常认识的大得多 ,应深入研究有机烃气寻找金属矿这一新方法。

Hydrocarbon gas survey performed around various rock bodies, ores, wallrocks and surface soils has revealed that organic matter took part in the ore forming process of the Gejiu ore deposit, that there exist hydrocarbon gas halos around orebodies, and that dintinct hydrocarbon gas anomalies are present over known orebodies. It is held that organic matter might have played a much greater role in precipitation, diagenesis, mobilization and migration as well as mineralization of metallic elements than we have already known. Hence, much more imporance should be attached to the study of applying organic hydrocarbon gas to the prospecting for metallic ore deposits.
