一问题的提出中国东南部前泥盆纪地质的发展特征及其构造性质,是长期以来中外地质学者所争论不休的问题,也一向被视为是我国大地构造学中一个最复杂、最困难、最吸引人兴趣的研究问题。由于广泛分布在粤、桂、湘、赣等省内的前泥盆纪地层,现被证实大部分是属于下古生代,且大多受过不同程度的变质,构造岩浆活动复杂,矿产蕴藏丰富,再加上在这期间的加里东运动的特征,往往又习惯地被地质学界用来作为辨识这一地区属
A question raised The developmental features and tectonic properties of the former Devonian geology in southeastern China have long been debated by geologists both in China and abroad and have long been regarded as one of the most complex and difficult problems in geotectonics in China. The most interesting research questions. Because of the Pre-Devonian strata widely distributed in Guangdong, Guangxi, Hunan and Jiangxi provinces, most of them are proven to belong to the Lower Paleozoic and are mostly metamorphosed in varying degrees with complex tectonic magmatism and abundant mineral deposits. The characteristics of the Caledonian movement during this period are often used by geologists as a way to identify the genus
