3D GEOLOGICAL MODELING AND DEEP PROSPECTING PREDICTION IN CHAMATUN IRON DEPOSIT, LIAONING PROVINCE

摘要:
查马屯铁矿是一处隐伏于中生代火山沉积岩之下的沉积变质型铁矿床，矿体规模大、埋藏浅，深部资源潜力巨大.利用三维地质体建模软件Creatar，通过收集钻孔数据，建立地质数据库，生成三维钻孔.通过剖面定义、单工程矿体圈定、剖面编辑、曲面连接，建立矿体三维模型.依据"点-线-面-体"的思路，建立了辽宁查马屯铁矿三维地质模型.模型显示，查马屯铁矿体西南段向北西倾斜，北东部向南东倾斜，呈北东东向展布，应沿该方向部署找矿.矿体与磁异常复合关系表明，2号矿体南部存在巨大找矿空间，查马屯村南部及北东部是下一步找矿勘探的重点方向.
Abstract:The Chamatun iron deposit is of a sedimentary metamorphic type buried beneath the Mesozoic volcanic sedimentary rocks with large orebody, shallow burial depth and great potential of deep resources. By applying the 3D geological modeling software Creatar and collecting borehole data, the authors establish geological database and generate 3D drilling. The 3D model of orebody is set up through section definition, single engineering delineation of orebody, section editing and surface connection. The 3D geological model of Chamatun iron deposit is built based on the thought of "point-line-plane-volume". The model shows that the iron orebody is distributed in NEE direction, with southwest part inclined to northwest and the northeast part inclined to southeast, thus prospecting should be accordingly deployed. The compound relation between orebody and magnetic anomaly indicates that the south of No. 2 orebody has great prospecting potential, and the south and northeast of Chamatun village could be the key for further prospecting and exploration.
