| 摘 要： | 本文以白龙江复背斜北翼的逆冲推覆断裂体系中的F3韧脆性复成因断裂为主要研究点,重点讨论了与该断裂相配套的、有利于形成矿床构造部位,岩浆岩特点和矿化及热液蚀变的特征。提出逆冲体系中的韧脆性复成断裂带在带内的相对"上隆"和"下陷"的边缘地区以及其过渡带是金矿成矿的有利地区。结合岩浆活动、热液活动和其它特点对研究区进行了成矿区的预测和分析。

| Abstract: | Studying from F3 ductile complex fault of thrusting-nappe fault system in North-limb of Bailongjiang composite anticline, it is focused to discuss the structure positions which tend to form ore deposit, the characteristics of magmatic rock and, the features of mineralization and hydrothermal alteration. It is pointed out that the best gold metallogenic area are at uplifting and sagging edge of ductile complex fault of thrusting-nappe fault system. By combination of magma activity, hydrothermal and so on, prognosis of metallogenic area in research region was made. |
