This paper deals with a preliminary study of 13 localities of Precambrian iron‐formations in the Jiamusi median massif and determination of the gold content of 391 samples. It has been ascertained that the gold deposits are strictly controlled by the iron‐formations and exhibit obvious stratabound features. On that basis, the paper principally discusses gold migration and enrichment. Abundant Mn and Co are contained in primary sediments of the Dongfengshan‐type gold deposits, which strongly supports and supplements the idea that the gold deposits of the same kind in the world are of metamorphosed volcano‐exhalative‐sedimentary origin.
