中文摘要:铁矿是吉林省的重要矿产,已发现249处矿产地。根据《中国矿产地质志》研编技术要求,吉林省的铁矿床被划分为岩浆型、接触交代型、岩浆热液型、受变质型、化学沉积型和风化型6个成因类型。文章系统总结了铁矿的成矿地质条件,并对不同地质时代产出的铁矿床类型、特征及其空间分布规律进行了初步研究;系统分析了主要含矿建造、成矿构造条件、岩浆作用及变质作用对铁矿成矿的制约,并以地质事件为主线,阐述了地壳演化与成铁作用的内在联系,系统论述了吉林省各种类型铁矿床的时空分布特征。本研究对了解吉林省铁矿成矿规律和找矿具有重要意义。
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.
