| 摘 要： | 铁岭—靖宇成矿带西段构造．岩浆活动具有多旋回特点。太古宙花岗．绿岩带是主要矿源层。通过对典型金矿床成矿特征的分析，区内主要发生2次金矿化，并形成2种主要类型的金矿床，即太古宙末—元古宙早期形成的受韧性剪切带控制的变质层控型金矿床和形成于燕山运动末期、受燕山晚期中酸性岩浆岩控制的岩浆热液型金矿床。主要的控矿部位是区域深大断裂交汇区，特别是叠加NW向断裂并发育燕山晚期中酸性侵入岩体的地段可构成金矿集中区。在上述研究的基础上进行了找矿预测。

| Abstract: | The tectonic-magmatic activity of the west of Tieling-Co-Jingyu mineralization belt had the features of multicycle. The granite-greenstone belt is the major source bed of the deposit. The analysis of the metallogenic feature of the classic gold deposit show that there are 2 times gold mineralization and forms 2 types gold deposit, that is the altered stratabound gold deposit controlled by the ductile shear zone of Later Archeozoic to Early Proterozoic and the magmatic hydrothermal deposit controlled by the middle-acid magmatic rock of Later Yanshanian. The major ore control place is the join point of the regional deep fault, especially where the NW strike fault developed and superpose the middle-acid intrusive rock of Later Yanshanian forms gold concentration area. On the base of the above study the prospecting forecast had been carried through. |
