摘要
有关赣北地区双桥山群内角度不整合和地壳运动存在与否问题,一直争论不休。论文以较丰富的详细野外调查资料为基础,并结合前人研究成果和室内各类样品测试结果,围绕这个赣北地区重要的基础地质问题进行了讨论。作者认为“修水运动”不能成立,并提出了砾岩的沉积模式。
The presence or absence of an angular unconformity within the Shuangqiaoshan Group in northern Jiangxi and the related crustal movement has long been, a subject of much controversy. Based on abundant and e-laborate field investigation and laboratory analytic data combined with the research results of previous workers, this paper has dealt with this important basic geological problem of the northern Jiangxi area. The authors hold that ' Xiushui Movement' is untenable, and a 'conglomerate depositional model' has been developed instead.
