摘要
本文在研究构造与金成矿的地质关系的基础上，从不同方向断裂充填物的微量元素的分 布特征、地质产状、粒度不同的黄铁矿中金的分布特征、不同期次的断裂充填物的微量元素分布特 征等方面详细探讨了构造与金成矿的地球化学关系。认为不同方向构造充填物的微量元素的分布 特征很好地反映出构造与金成矿的关系。粗粒破碎的黄铁矿含金较高，说明构造运动使金在黄铁 矿中进一步富集。不同期次的断裂充填物的微量元素分布特征研究同样说明了构造对金的富集起 到了十分关键的作用。Ｈｇ、Ｗ、Ｍｏ、Ｆ等微量元素在构造作用下的地球化学行为说明燕山期构造运 动对本区金的成矿仅仅起到了进一步富集的作用。
On the basis of the study of geological relationships between structure and gold metallogenesis, their geochemical relationships have been studied in this paper in many aspects such as trace elements distribution in infilling guests in all directions and stage faults, gold distribution in pyrites with different occurrences and sizes, which suggest that the features of trace elements distribution have fit in with their geological relationships. Coarse-crystallized crushing pyrites with high gold content suggest that gold is enriched by tectogenesis. Trace elements distribution in infilling guests of different stage faults implies that tectonic activities have played an important role in gold enrichment. The geochemical actions of trace elements, such as Hg, W, Mo, F, under the tectonic activities show that Yenshan movement has just further enriched gold mineralization in the process of gold metallogenesis.
