摘要
该金矿地处丰宁台凸之上,南猴顶花岗杂岩体东北侧,元古宇—太古宇旋回的闪长岩、角闪石岩(后经强烈区域变质作用形成变闪长岩)构成本区的主要成矿围岩(含矿母岩)。文章通过对该矿床成矿特征的分析,总结了在该区的找矿标志及有利的成矿地段。
The Dayingzi gold deposit is located on the Fengning platform and the northeast of the Nanhouding granite body. The ore - bearing wall rocks include Proterozoic - Archean diorite and amphibolite which became the metadiorite after the strong regional metamorphism. The metallogenic characteristics and enrichment of the deposit are analyzed in this paper according to the geological characteristic of ＂the Trinity＂.
