【摘要】：本文以辽宁阜蒙地区中生界火山岩覆盖区为研究对象,通过对区域地质背景、地球物理特征、典型矿床的分析,结合野外地质及物探磁异常反演解译成果,运用creatar建模平台,构建阜蒙地区三维地质结构模型、典型矿床——查马屯铁矿三维地质结构模型。进行综合、集成研究,对比分析,提取成矿、控矿要素,确定其空间分布、结构等之间的相互关系,运用三维地质结构模型,预测成矿远景区,为进一步圈定深部远景区奠定基础。辽宁阜蒙地区多为中生界火山岩及第四系覆盖,下覆多为太古界地层,而太古界地层正是沉积—变质型铁矿(鞍山式铁矿)的附矿层位。由于太古界地层多被覆盖,因此本区存在铁矿多为隐伏矿体,受中生界火山岩的影响,该区找矿工作难度较大,铁矿资源未能得到有效开发利用。本次利用三维建模技术重点构建该区三维地质模型及典型矿床三维地质模型,为该区铁矿找矿工作提供技术支持,使该区铁矿资源得到开发利用。
[Abstract]:In this paper, the Mesozoic volcanic rock overlying area in Fumeng area, Liaoning Province is taken as the research object. Through the analysis of regional geological background, geophysical characteristics, typical deposits, combined with the results of inversion interpretation of field geology and geophysical magnetic anomalies, the creatar modeling platform is used. Three dimensional geological structure model of Fumeng area and three dimensional geological structure model of typical ore deposit-Chamakun Iron Mine are constructed. Comprehensive, integrated research, comparative analysis, extraction of ore-forming elements, ore-control elements, determination of their spatial distribution, structure and other mutual relations, using three-dimensional geological structure model, to predict the metallogenic scenic area, For the further delineation of deep scenic spots lay the foundation. Mesozoic volcanic rocks and Quaternary strata cover most of Fumeng area, Liaoning Province, and Archean strata are covered by the lower strata, which are the secondary strata of sedimentation-metamorphic iron ore (Anshan iron ore). Because the Archaean strata are mostly covered, there are many iron ore bodies in this area, which are influenced by Mesozoic volcanic rocks, so the prospecting work in this area is difficult and the iron ore resources can not be effectively exploited and utilized. In this paper, 3D geological model and typical deposit 3D geological model are constructed by using 3D modeling technology, which provides technical support for ore prospecting in this area and makes iron ore resources in this area be exploited and utilized.
