英文摘要	Through lithologic mapping to achieve ore concentration district transparent within 5km depth is the main way to realize deep fine structures study, to explore deep mineral resources and to reveal metallogenic regularity of large-scale ore district. Owing to the wide covered area, high sampling density and mature three-dimensional inversion algorithm of gravity and magnetic data, so gravity and magnetic inversion become the most likely way to achieve three-dimensional lithologic mapping at the present stage. In this paper, we take Lu-Zong (Lujiang County to Zongyang County in Anhui Province, East China) ore concentration district as an example, we proposed lithologic mapping flow based on 3D inversion of gravity magnetic and then carry out the lithologic mapping test. Based on the analysis of relations between lithology and density and magnetic susceptibility, 3D inversion with prior information of high-precision gravity and aeromagnetic data were carried out. Then, we use logical topology operations between density 3D model and susceptibility 3D model obtained three-dimensional distribution of five main type lithologies in the Lu-Zong ore concentration district within 5km depth. The result of lithologic mapping not only showed that the shallow characteristics and surface geological mapping are basically coincide, more importantly reveals the deeper lithologic changes, it make up the insufficient of surface geological mapping. The lithologic mapping test results in Lu-Zong ore concentration district showed that Ethological mapping using 3D inversion of gravity and magnetic is a effective method to reveal the lithological characteristics and to explore deep mineral resources in ore concentration district.
