主　　题：Horne deposit massive sulfide three-dimensional geological modeling hydrothermal alteration 

摘      要：The Horne deposit with rich Cu and Au in Noranda region of Black River Group in Quebec has high economic *** researches on Horne deposit are mostly based on two-dimensional maps and statistical *** is hard to reflect the spatial structure and characteristics of Horne orebody *** this paper,GIS was used to digitize the mining plan-view maps at different depths,stope maps,the boundary of the massive sulfide in drilling trajectories as well as the grade data of Au and Cu of Horne ***,the authors established the grade attribute *** the three-dimensional(3D)geological model and grade attribute model of Horne orebody were established by Geological Object Computer Aided Design(GOCAD).Positions of two vents and directions of hydrothermal alteration in Horne deposit were inferred based on the property of the major fault,characteristics of hydrothermal alteration,the enrichment morphology and spatial distribution of high-grade Cu in the Cu attribute model.
