Abstract

Abstract

Aimed at solving the complicated geological problem of Daye iron deposit in Hubei Province, this paper applies the techniques of probability analysis and physical property inversion to realize fine processing and interpreting of high-precision 3D gravity and magnetic data in the Daye iron deposit, and proposes a significant reference for the prospecting in the deep and surrounding of mines. We inverted the strong aeromagnetic anomaly with 3D probability tomography under no-constraints, completed 3D magnetic interactive inversion with the help of topography and other prior geological information, and forecasted the space extended state for the contact zone of sedimentary rock and diorite in the mining areas. Then we inverted 3D physical property characters within a fixed quantity in the areas. The inverse results show that the significant prospecting zones are distributed in the deep (under 1 000 m) and the flexures of the contact zones in the mining areas. These predicted zones had been proved by the practical logging.
