皖南南部构造性质及构造单元的归属的争论,在最近一次全国性编图会议,意见仍未统一。作者在实际调查材料的基础上,运用构造——建造分析和比较大地构造的方法研究了本区前寒武纪及早期古生代各时代建造成分,确定了各建造的名称、性质和空间分布特征,进一步划分出几个不同性质的建造序列;描述了不同时代地层和不同空间的构造形态,划分了构造层及构造形态的级别,並分析了构造形态形成的原因;论证了本区加里东运动的存在及其性质。在上述资料基础上,阐明了本区是华南加里东地槽区皖南浙西加里东地槽系的重要组成部分,並对皖南加里东地槽与其北隣的下扬子台缘沉陷带的界限予以确定,进一步说明了本区在加里东旋迴是冒地槽,具有残余地槽和边缘地槽拗陷的特性。
The controversy over the tectonics and the ownership of tectonic units in the southern part of southern Anhui has not yet been unanimously agreed at the latest national compilation conference. Based on the actual survey materials, the authors used the tectonic-construction analysis and comparatively large-scale structural methods to study the components of the Precambrian and early Paleozoic eras in each stage of the study, and determined the names, properties and spatial distribution characteristics of each construction. Further divided into several different types of construction sequence; described the formation of different age strata and different spaces, divided the tectonic level and tectonic level, and analyzed the reasons for the formation of tectonic forms; demonstrated the Caledonian movement Existence and its nature. Based on the above data, it is clarified that this area is an important part of the Caledonian geosynclinal system in the southern part of Southern Anhui and the southern part of the Galliferong terrain in southern China, and the boundary between the Galliferong trough in southern Anhui Province and its subordinate Lower Yangtze margin is given Determine and further explain that this area in Caledonian gyration is a typhoon, with the residual groove and the marginal groove depression characteristics.
