摘要
The Nihe iron deposit is a large-scale iron and sulfur mine of volcanic type.It was found by applying the ore-search theory and verifying the magnetic anomalies.It was appraised as a new mechanism for mineral exploration,the “Nihe Model”.In this area,the distribution of ore-bodies coincides with the residual gravity anomalies;original magnetic is characterized by negative △T,and the positive △T anomalies are loose and disordered without distinct difference from the surroundings.The △T reduction to the pole has low intensity,with a better form after upward continuation or filtering,consistent with the distribution of ore-bodies.These are the most important basis for orebody validation and borehole deployment.
