通过对杨家杖子燕山期各期侵入岩与辉钼矿矿化间时空关系的剖析及其岩石学、岩石化学、副矿物和微量元素等方面特征的研究,作者认为,本区燕山期侵入杂岩体晚期的花岗斑岩类小侵入体与钼矿化具有最密切的空间、时间和成因联系。花岗斑岩顶部围岩裂隙以及与碳酸盐围岩接触的内外接触带是钼矿富集的主要有利部位。并在分析总结的基础上,提出了本区今后的找矿方向。
Through the analysis of temporal and spatial relationships between the intrusive rock and molybdenite mineralization in the Yangzazhang sub-stage of the Yanshanian period and their petrology, petrochemistry, accessory minerals and trace elements, the authors believe that the intrusive characteristics of the Yanshanian intrusive Late granitic porphyry small intrusions and molybdenum mineralization has the closest space, time and genesis. The granite porphyry at the top of the surrounding rock fissures and contact with the carbonate rock contact with the outer and inner contact zone is the main beneficiary of molybdenum enrichment sites. On the basis of the analysis and summary, the direction of prospecting in this area is put forward.
