中文摘要:东升庙矿床位于内蒙古自治区达茂旗境内,文章通过收集矿区钻孔数据建立了矿区地质数据库,建立了矿区的地表模型,运用图切剖面法建立了矿体的三位地质可视化模型,通过对矿体模型的分析认为,矿体多赋存于断裂带裂缝内及褶皱的节理中,该矿具有多期次成矿特点,接近于地表的矿体多为沉积型矿床,而深部的矿体多为热液型矿床,而该矿主要矿床成因应为沉积型矿床,深部矿体在后期经历了岩浆热液的破坏作用导致其矿体形态变化较大。

Study on ore body morphology and ore deposit genesis based on three-dimensional geological model: a case study of Dongshengmiao, Inner Mongolia
Abstract:Dongshengmiao deposit is located in Damaoqi of Inner Mongolia Autonomous Region. The geological database of the mining area is established by collecting borehole data of the mining area. The surface model of the mining area is established. The three-dimensional geological visualization model of the orebody is established by using the method of graph-cut section. The analysis of the ore body model shows that the orebodies are mostly hosted in faults. The ore bodies close to the surface are mostly sedimentary deposits, while the deep ones are mostly hydrothermal deposits. The main genesis of this ore deposit should be sedimentary deposits. The deep ore bodies undergo magmatic hydrothermal destructive action leading to the morphological changes of the ore bodies in the later period Larger.
