| 摘 要： | 以乌努格吐山试验区钻孔岩芯中MgO、CaO、Na2O贫化现象为切入点,结合乌努格吐山斑岩铜钼矿床蚀变分带明显和矿化特征,发现钻孔中CaO、MgO、Na2O等组分相对各自丰度明显贫化的信息可以反映到地表岩石上来。讨论了这种贫化信息与成矿元素Cu、Mo在钻孔岩芯和地表岩石中的关系,并对该试验区47种元素的地球化学特征进行研究,讨论了这些元素的富集贫化特征与成矿元素和CaO、MgO、Na2O等组分构成的整体元素地球化学特征。根据该矿床的富集与贫化两类元素所表现的地球化学特征,建立该矿床地球化学异常结构。此项成果对斑岩型铜钼矿床地球化学勘查方法与理论的完善具有重要意义。

| Abstract: | In view of the remarkable depletion of such major components as CaO,MgO and Na2O in the drill holes,in combination with the obvious alteration zoning and the mineralization characteristics of the Wunugetushan porphyry Cu-Mo deposit,the authors have found that the information of the depletion of CaO,MgO and Na2O in the drill holes has reflection at surface.In this paper geochemical characteristics of 47 kinds of elements in this ore deposit were studied.The enrichment and depletion characteristics of these e... |
