老堡铅锌矿床主要赋存在陡山沱组白云岩或老堡组硅质岩中,顺层产出,受地层与褶皱的双重控制.矿区主干褶皱为一复式向斜,由2个次级向斜和1个次级背斜组成.从构造几何学、运动学角度,运用现代测试技术,对矿区的小构造、显微构造和组构进行构造分析后揭示,老堡褶皱构造的形成机制是以弯滑作用为主、兼具弯流作用的纵弯褶皱作用的产物.铅锌矿体主要赋存在褶皱的转折端虚脱部位及两翼滑移量较大的层间滑动破碎带中.

Laobao Pb-Zn deposit mainly beds in the dolomite of the Doushantuo Group and in the silicalite of the Laobao Group, and is controlled both by strata and folds. The main fold in the mining area is a compound syncline, composed of two sub synclines and one sub anticline. Based on the tectonic, geometric and movement features, the analysis on the small structures and micro-structures and fabrics reveals that the formation mechanism of Laobao folding structure is the result of the longitudinal flexural folding,featuring by flexure-slide and flecure-flow folds. The Pb-Zn ore mainly exists in the decollement zones around the diversion areas and in the interformational gliding fracture zone in both wings within the fold.
