Abstract

Abstract

3D geological modeling is an important method and frontier of mineral resources exploration and assessment in the world. In this paper, a case study of the Luanchuan molybdenum polymetallic ore belt which has complicated geological setting and diversity metallogenic condition of geology, 3D geological modeling is combined geological knowledge with gravity and magnetic data integration. The research contents, methods, and results are summarized as the following aspects: (1) based on the geological setting and metallogenic conditions to determine the deposit characteristics of the study area and the near-surface geological object features of the spatial properties; (2) on basis of geological information in the qualitative interpretation using gravity and magnetic data, 2.5D forward interpretation and 3D imaging method of potential field inversion and interpretation of the probability of deep geological objects; (3) combination geological data with gravity and magnetic inversion datas to determine the space-time-genesis relationship among the Late Jurassic porphyry rock, ore, and ore mineralization favorable geological structures. The research results show that combination the geological characteristics including rock properties with inversion of gravity and magnetic interpretation to define geological object geometries, which is beneficial for geological prospecting, delineation of the quantitative evaluation of prospecting targets.
