Geological Characteristics and Ore-forming Regularity of Xingfucun Gold Deposit in Inner Mongolia

Xingfucun gold deposit,located in the Bayunerbo to Shangdu metallogenic belt at the western section of north margin of North China platform,and the gold orebodie mainly exist in the Bayunerbo group Bilute fabric phyllite,in southern limb of the Erligetu overturned syncline.Through study on ore controlling factor from stratigraphic formation,tectonic movement and magmatic activity etc.,we think that the gold ore-body is formed under the integrated function of strata,fractures and magmatic rocks,namely stratum is ore bearing layers.while structure played ore conducting function and the magmatic activity provided heat source and possible ore liquid or dynamic force.Combining with the analysis of deposit geological features,comparing regional different gold deposits,the genesis of Xingfucun gold deposit is attributed to the meso-epithermal type of gold deposits hosted by low-grade metamorphic rock.We initially establish the ideal mineralization model of the area based on the analysis of the mineralization,and we suggest that further prospecting work should focus on the area of north-dipping direction,especially area near the core where is the favorite part of mineral enrichment and mineralization.
