TECTONIC DEFORMATION OF THE XUEFENG UPLIFT AREA IN HUNAN

摘要: 从分析湖南雪峰隆起区的构造变形特征入手，划分了该隆起区从中元古代以来所经历的三次大的构造变形阶段：元古代中期末的武陵构造变形－北部雪峰隆起初步形成（隆起雏型）阶段；古生代早期末的加里东构造变形－南部雪峰隆起形成并使统一连贯的雪峰隆起初具成型的阶段；中生代印支、燕山叠加构造变形－雪峰隆起成型并定型阶段。志留纪末的加里东运动是形成雪峰隆起的重要构造运动。Abstract: On the basis of an analysis of the features of tectonic deformation in the Xuefeng uplift area,Hunan, three major stages of tectonic deformation that this uplift area had undergone since theMiddle Proterozoic have been distinguished: terminal Middle Proterozoic Wuling tectonic defor-mation-initial formation of the northern Xuefeng uplifti Caledonian （terminal Early Paleozoic） tec-tonic deformation-formation of the southern Xuefeng uplift and initial formation of the unifiedXuefeng uplift; Indosinian and Yanshanian （Mesozoic） superimposed tectonic deformation-finalformation of the Xuefeng uplift. The Caledonian movement at the end of the Silurian was an im-portant movement for the formation of the Xuefeng uplift.
