摘　　要：吉林省南部荒沟山地区的珍珠门组可以分为:(1) 条带状大理岩;(2) 厚层状大理岩两个岩性段。变形分析表明它至少经历了三期变形,其中第二期变形对本区构造格架影响甚小。第三期北北东向直立褶皱叠加在第一期北北西向平卧褶皱之上形成的异轴异面褶皱叠加型式是本区的特征性构造样式。荒沟山铅锌矿与朝鲜检德铅锌矿类似,并且处于同一早元古代活动带内。朝鲜检德铅锌矿主要控矿构造是第一期褶皱转折端,因此荒沟山地区第一期褶皱转折端也应是寻找检德型大型铅锌矿的有利部位,本文提出了第一期褶皱转折端的可能部位,即寻找大型铅锌矿的有利部位。The Zhenzhumen Formation of Laoling Group in the Huanggoushan region, southern Jilin province can be divided into the following lithostratigraphic units: (1) banded marble, (2) thickbedded marblr. The detailed struetural analysis to be made in this region suggest that Zhenzhumen Formation underwent at least three episodes of deformation, but the second had not an obvious influence on the structural framework, The characteristic structural pattern is represented by the heterotaxial axle-plane superimposed fold which was formed by the superimposition of the NNE trend up right fold of the third episode and the NNW trend recumbent fold of the first episode. The Huanggoushan Pb-Zn deposit is within the active belt of early Proterozoie and similar to Komdek, North Korea Pb-Zn deposit, that main ore-control tectonics is the first episode nose of fold, So the Huanggoushan region should be the favourable Pb-Zn mineralizing place because there is the nearest to the hinge zone of fold of the first episode deformation.
