摘要:
提要:铁矿是中国重要的大宗金属矿产资源,对其进行成矿规律总结和潜力分析具有重要的理论和实际意义。本文总结了中国铁矿资源的禀赋特征;将中国铁矿床分为沉积变质型、岩浆型、接触交代-热液型、火山岩型、沉积型和风化淋滤型6种成因类型和40个矿床式,并建立了鞍山式沉积变质型、大庙式岩浆型、蒙库式海相火山岩型、大西沟式沉积型铁矿床的成矿模式;划分了36个中国铁矿成矿区带,编制了成矿区带图,总结了不同类型铁矿和不同时代铁矿的空间分布规律;总结了矿床类型、矿床规模和矿石类型的时间分布规律;最后,探讨了7个重点成矿区带的资源潜力。

Abstract:
Abstract:Iron resource is an important metal resource in China. Summary of iron metallogeny and analysis of iron resource potential are of theoretical and practical significance. This paper summarizes the natural endowment characteristics of the iron resource in China. Iron deposits in China are classified into metamorphosed sedimentary-type iron deposits, magmatic-type iron deposits, contact metasomatic-hydrothermal-type iron deposits, volcanogenic type iron deposits, sedimentary type iron deposits and weathering-infiltration type iron deposits as well as 40 typical iron deposit styles. Metallogenic models of Anshan type, Damiao type, Mengku type and Daxigou type iron deposits are established. This paper divides China’s iron resource into 36 iron minerogenic units, and also summarizes the temporal and spatial distribution of iron deposits of different genetic types, different deposit sizes, and different ore types. The resource potential of 7 important minerogenetic units is also discussed.
