锡铁山铅锌矿床含矿岩系主褶皱是一个由绿片岩片理（Ｓ０＋Ｓ１）褶皱而成的斜卧褶皱。主褶皱枢纽沿走向波状起伏，转折端较开阔，两翼向深部紧闭。研究表明：矿体主要赋存于主褶皱转折端大理岩与绿片岩间的构造虚脱空间内，明显地受主褶皱空间展布、形态及完整性的影响和控制。主褶皱的初步厘定及相关构造特征研究，对重新认识该矿床的构造控矿形式，确定找矿方向具有指导意义。
The main fold of the Xiantishan lead-zinc ore-bearing rock series is a reclining fold formed by folds of greenschist (S0 + S1). Main fold hinge along the wavy ups and downs, the turning point is more open, the two wings closed to the deep. The results show that the orebodies mainly occur in the structural collapse space between the marble and the green schist at the turning point of the main fold, which is obviously influenced and controlled by the distribution, shape and integrity of the main fold space. The preliminary determination of the main fold and related tectonic characteristics are of guiding significance for re-understanding the structural ore-forming pattern of the deposit and determining the prospecting direction.
