摘要
Based on palaeomagnetic studies of the Precambrian gold deposits in the Xiong'ershan area. Henan Province, the authors infer that the ore-forming processes of the Beiling alteration-type gold ore deposit and the Dianfang breccia-type gold ore deposit started in the Proterozoic, and was superimposed by later mineralization, whereas the mineralization age of the Jiguanshan quartz-vein type gold ore deposit is Yanshanian.
