Abstract

Abstract

In recent years, 49 chromite deposits (ore occurrences) including 1 medium-sized deposit, 11 smallsized deposits and 37 occurrences have been discovered in North China.These chromite deposits (occurrences)are mainly distributed in Inner Mongolia, Hebei, Henan and Beijing provinces,which strictly controlled by Ophiolites and distributed spatially along the ophiolite belts, such as Shangdan, Suolunshan and Hegenshan.They were formed in Archen to Mesozoic, and Neoarchean-Paleoproterozoic and Late Paleozoic were heyday period of chromite mineralization.The ophiolite type is mainly chromite deposit type, followed by magmatic type.The comprehensive analysis shows that several ophiolitic melange belts such as Erlian-Hegenshan, Suolunshan, Kedanshan and Shangdan have good prospecting potential for chromite deposits in Inner Mongolia.Deep exploration and peripheral investigation of known mining areas should be strengthened to achieve a breakthrough in chromite prospecting.
