郯庐古岛弧构造系与金矿成矿的关系

本文从郯庐断裂带整体地质构造特征出发，应用板块构造理论和遥感技术、地质调查、物化探等综合研究方法，初步提出郯庐断裂带应归属于东亚大陆古岛孤－新裂谷式巨型构造系统，它与现代西太平洋岛弧具有“相对应性”及“等结性”控制金矿成矿集中区的新认识，并据此探索和总结了金矿（含其他矿产）的成矿规律，为寻找“招掖”式金矿进行成矿前景预测。

THE RELATION BETWEEN TAN-LU PALAEO-ISLAND ARCSTRUCTURAL SYSTEM AND GOLD METALLOGENESIS

Starting from the whole geological structural characteristics of the Tan-Lu fault belt andapplying comprehensive research methods such as remote sensing techniques,geological survey,geophysical and geochemical exploration,and plate tectonic theory,this paper preliminarily puts forward a new recognition that Tan-Lu fault belt should be attributed to the giganticstructural system of palaeo-island arc-recent rift pattern in East Asian continent,and it has a"correlativity"and "iso-distance structural intersection"with modern west Pacific island arc,which controls the concentration area of gold mineralization. On this basis,the gold(includingother mineral resources)metallogenetic regularities have been explored and summarized,andmetallogenetic prospect prognosis has been made in order to seek for the large scale"Zhaoyuan"type gold deposit.
