摘要
The 781 uranium ore spot in Luotuoshan area of Baochang volcanic basin,is located in the western part of the Yanshan—Liaoning tectonic region and is one of the most important ore deposit areas which are recently found in the Yanshan—Liaoning uranium ore deposit belt. Based on an integrated study of the data of the seventythree drill-cores,topography,strata and sections in the 781 uranium ore spot and with the application of the Surpac 3D software,three-dimensinal model was constructed,visually displaying the distributing characteristics of the topography,strata,tectonic and orebodies. The results of the three-dimensional model indicate that the buried F a fault is the most relevant ore-transmitting and ore-controlling structures,and the Upper Jurassic Manitu Formation is important ore-hosted strata and uranium-source beds. The factors of ore-controlling structures,the distributing characteristics of the orebodies,the law of ore-bearing and the application of the Surpac 3D software lead to location prediction that Ⅰand Ⅱ areas are the prospecting target areas which have the exact three-dimensional coordinate and play an important role for the deep mineral prospecting.
