| 摘 要： | 江西九岭地区位于扬子板块东南部，发育的中元古代地层为一大套以砂泥质为主、含少量火山物质的复理石建造。经历了多期变形变质作用，在地质体中留下了丰富的地质事件信息。本文对这些信息进行了综合分析，阐述了它们的基本特征，探讨其内在联系和相互关系及其演化过程，主要论述了褶皱变形构造、韧性剪切带、脆性变形构造、构造变形与变质作用的关系。在此基础上，将其变形变质事件的演化序列划分为：四堡一晋宁变形变质构造期，加里东变形变质构造期，海西─印支─燕山─喜山变形变质构造期。

| Abstract: | The Jiuling area of Jiangxi Province lies in the southeastern part of the YangziPlate, the Mesoplnterozoic stratum is a flysch formation in the area it is mainly composed of theargill arena(eou) material, containing a small amount of the volcanic material. It had experiencedrnaltiple deformations and multiple metamorphism.This paper describes the main characteristicsof its folding deformation, ductile shear zone and brittle de fo~tion, and the retations betweenthe tectonic doformation and metamorphism. The deformation and metarnorphism it had beenexperienced with can be divided into three oragenic periods: The Sibao-Jinningian, Caledonianand Hercynian-Himalayan movements. |
