摘要: 从江西北部中元古界双桥山群中硅质岩的分布入手,对硅质岩的岩石特征及含矿性进行了描述,从空间分布、物质来源及矿床成因上探讨了硅质岩与韧性剪切带及"金山式"金矿的联系,指出了该套硅质岩在德兴地区不仅是"金山式"金矿的直接赋矿岩石,更是一种重要的找矿标志,对德兴以外的其他地区寻找"金山式"金矿具有十分重要的指示意义.

Abstract: Considering the distribution of the silicalite of Mesoproterozoic Shuangqiaoshan group in the north of Jiangxi Province, the lithology and mineralization of the rock is studied. The relations between the silicalite and ductile shear zone as well as "Jinshan type" of gold deposits are discussed in the aspects of their distribution, material sources and genesis of gold deposits.The silicalite is not only the direct host for the "Jinshan type" of gold deposits in the area, but also an important indicator of exploration. It is significant in the searching for gold deposits of the type beyond Dexing area.
