赣杭构造带是从赣中往北东延伸至浙江杭州湾的一条火山岩带,在大地构造上属于扬子与华夏两个古陆块于新元古代碰撞拼接所形成的结合带。赣杭构造带西段的火山岩系,根据火山喷发旋回、地层层序与接触关系,可以划分为打鼓顶组和鹅湖岭组。打鼓顶组和鹅湖岭组在赣中地区和北武夷地区多个盆地均有分布,如相山盆地、盛源盆地和冷水坑盆地。对于这两套火山岩地层的时代归属却存在着较大争议。对相山盆地的研究较多,结果表明该盆地
The Gan-Hang tectonic belt is a volcanic belt extending from the central Jiangxi to the north-east to Hangzhou Bay, Zhejiang Province. It belongs to the combination belt formed by Neoproterozoic collisional splicing of two ancient land masses of Yangtze and Huaxia in the tectonic setting. Volcanic rocks of the western segment of the Gan-Hang structural belt can be divided into the Gaogutou Formation and the Ehuhuling Formation according to volcanic eruptions, stratigraphic sequence and contact. The Taigu Formation and Ehulling Formation are distributed in a number of basins in central Jiangxi and northern Wuyi, such as the Xiangshan Basin, Shengyuan Basin and Lengshuikeng Basin. There is much controversy over the age ownership of these two volcanic formations. The Xiangshan Basin is more studied and the results show that the basin
