耒阳—临武南北构造带,是湘南醒目构造形迹之一,它形成于印支运动,是由一系列紧密疏状褶皱及断裂组成。该带受后期燕山运动的影响,特别是新华夏构造的叠加,促使南北向构造呈反“S”形的扭曲。在这些褶皱系向东或向西突出的弧形地带及其附近,常是岩浆活动或内生金属矿床形成的良好地区。本文主要叙述该带构造形式的特点以及它们与成岩、成矿的关系。
Mianyang - Linwu North-South structural belt, is one of the striking structural features of the southern Hunan, which formed in the Indosinian movement, is composed of a series of tight sparse folds and fractures. This belt was affected by the late Yanshanian movement, especially the superimposition of the Neo-Huaxia structure, causing the anti-S-shaped distortion of the NS structure. In and around these arc-shaped belts that project to the east or west, these folds are often good areas for magmatic activity or endogenic metal deposits. This paper describes the characteristics of the belt structure and their relationship with diagenesis and mineralization.
