| 摘 要： | 本文就扬子板块东南缘湖南段上元古代三套同期异相沉积层—泥市群、板溪群及高涧群的构造变形特征分别作了简要概述。指出它们的主体构造变形是显生宙以来构造叠加变形的综合反映,其中,板溪群与高涧群的构造变形型式迥然有别,“雪峰隆起”的南北两侧不仅在组成上而且结构上均具显著的不对称性。

| Abstract: | This paper discusses the tectonic reformation features of the Upper Proterozoic subera three isogenetic heteropical deposits - Nishi group, Banxi group and Gaojian group in Hunan area, southeast margin of the Yangtze plate. The major tectonic reformation is resulted from tectonic reformation superposition since Phanerzoice, in which the tectonic reformation mode of Banxi group is different from that of Gaojian group forming obviously asymmetrically on north and south sides of "Xuefeng rise" in composition and structure. |
