摘要
通过对大观金矿的成矿地质背景及矿床地质特征的分析,对构造逐级控矿规律和构造界面控矿规律的研究,认为大观金矿F1为主要控矿断裂,是重要的容矿构造及导矿构造;主要控矿构造界面为许满组和罗楼组的界面,该界面是岩性组合界面(Si/Ca界面),在断裂构造的耦合作用下,形成大观金矿床。
Based on the analysis of metallogenic settings and geological characteristics of Daguan gold deposit and through the study on the stepwise structural ore-controlling regularity and structural interface ore-con trolling regularity, the author believed that F1 of Daguan gold deposit was the main ore-controlling fracture, an important ore-hosting and ore-transmitting structure. The ore-controlling structural interface was the interface between Xuman Formation and Luolou Formation, which was a lithological association interface （Si/Ca interface）. Daguan gold deposit was formed under the coupling effect of fracture structure.
