Abstract:Iron ore is an important mineral in Jilin Province, 249 ore deposits and occurrences have been found. According to the technical requirements for compiling the book《Geology of Mineral Resources in China》, the iron deposits in Jilin Province are classified into six genetic types: magmatic type, contact metasomatic type, magmatic hydrothermal type, metamorphic type, chemical sedimentary type and weathering type. This paper systematically summarizes the ore-forming geological conditions of iron deposits, and makes a preliminary study on the types, characteristics and spatial distribution of iron deposits in different geological ages. Archean strata are the most important iron ore-hosting geological bodies in Jilin Province, including Banshigou Group, Longgang Group, Jiapigou Group and Nangang Group. They are a set of metamorphosed submarine volcanic sedimentary ferrosilicon formation. The Proterozoic iron bearing geological bodies are mainly distributed in the Liaoji rift and Jihei orogenic belt, and the genetic types are mainly magmatic type hosted within basic intrusive complex and metamorphic type hosted within metamorphosed basic volcanic sedimentary rocks and clastic or carbonate sedimentary rocks. The main controls to the formation of the iron ores are iron rich strata, tectonic and structure, as well as magmatism and metamorphism. Taking geological events as the main line, this paper discussed the internal relationship between crustal evolution and iron formation, and systematically summarized the temporal and spatial distribution characteristics of various types of iron deposits in Jilin Province.
