Abstract: This paper is the study on the ore-forming laws and prospecting predictions of chromite deposits in the Hegenshan area, Inner Mongolia.Objective Summarize the geological, geophysical, and geochemical characteristics of chromite deposits in the Hegenshan area of Inner Mongolia, summarize the regional ore-forming elements and prospecting indicators, and conduct research on prospecting prediction. Methods In the Hegenshan area of Inner Mongolia, regional gravity, magnetic methods, and physical property measurements were carried out. ResultsThe results of regional gravity and aeromagnetic surveys show good consistency between high-value anomalies and ultrabasic rocks and major faults, thus identifying 34 areas with local gravity anomalies and inferring 5 faults. Conclusions Based on the comprehensive analysis of regional geology, geophysics, geochemistry, and other ore-forming elements and prospecting indicators, summarize the ore-forming laws and delineate 9 prospecting areas.
