SILICALITE OF SHUANGQIAOSHAN GROUP IN DEXING AREA, JIANGXI PROVINCE: Its significance in searching “Jinshan type” of gold deposits

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.
