新疆松湖铁矿床位于伊犁地块东北部，矿体赋存于下石炭统大哈拉军山组火山碎屑岩中．目前共圈定5个矿体，L1、L2出露，IJ3、L4、L5矿体隐伏，其中L1规模最大，也是该矿床主要矿体．矿床主要矿石矿物为磁铁矿，次为赤铁矿、黄铁矿和褐铁矿．矿石构造类型主要为浸染状、块状、角砾状和条带状构造．蚀变类型主要有绿帘石化、绿泥石化、阳起石化和钾长石化．矿床形成经历了隐爆一矿浆成矿期和热液成矿期2个阶段．该矿床成因类型属于受热液作用交代改造的火山岩型铁矿．

Songhu ore deposit is located in the northeast part of the Yili plate in Xinjiang. Its ore body occurs in the lower Carboniferous volcaniclastic rocks of the Dahalajunshan formation. Until now, five ore bodies have been delineated in the deposit area. Among them, L1 and L2 are exposed, and L3, L4 and L5 are buried. The L1 is the largest and the main ore body of the deposit. Magnetite is the main mineral, and the others are hematite, pyrite and limonite. As for the structure, the ore is com- posed of disseminated, massive, brecciated and banded structure types. The main alteration types consist of epidotization, choritization, actinolitization and K-feldspathization. The deposit has experi- enced two formation stages, the cyptoexplosion and magma ore forming periods and the hydrothermal metallogenic period. The genesis of the ore deposit belongs to the volcanic type iron ore deposit which had been transformed by hydrothermal process.
