【Abstract】 Almost all main types of China’s iron ores,whether occurred in the form of regional metallogenic belt or ore field,ore depositor orebody (ore shoot),are spatially distributed along the marginal parts of geological structures of different sizes and patterns andare controlled by these structures,among which they are tectonic plate,platform,geosyncline,palaeo-ocean basin,intrusive mass,and stratum(rock) boundary.The ores were formed in different geological epoches or at the early or later period (i.e.marginal peri-od) of the metallogenetic epoch.This is due to the different factors of time-space relations existed along these margins.For this rea-son to search along the marginal part for the iron ores formed in the marginal period will achieve greater,faster,etter and moreeconomical results.更多还原
