| 摘 要： | 通过对辽东二户来地区已发现矿床中各代表性钻孔资料进行连井对比分析，总结出该地区滑石矿成矿因素主要有3个方面：1）成矿母岩为古元古界大石桥组（Pt1d）白云石大理岩和含硅白云质大理岩；2）成矿热液来自燕山期侵入的硅酸盐热液；3）控制矿体形态、产状和空间分布特征的主导因素为受区域东西向构造影响而产生的层间裂隙、断裂破碎带.并根据对其成矿特征的研究，预测找矿远景靶区.

| Abstract: | Through the correlation analysis of the representative drill holes in the talc deposits founded in Erhulai area, Eastern Liaoning, the metallogenic factors are summarized in three aspects. First, the metallogenic rocks are the dolomite marble and silicon-bearing dolomitic marble of Paleoproterozoic Dashiqiaoan formation. Second, the ore-forming fluid is the silicate hydrothermal solution intruded in Yanshanian. And third, the leading factors that control the shapes, occurrences and spatial distributions of the orebodies are the fault belts and interbedded fractures, which are affected by the regional E-W-trending structure. Based on the study of metallogenic characteristics, the prospecting targets are predicted. |
