新发铁矿位于四川省会理县通安区,矿石质量好、埋藏浅、易开采,是三线建设铁矿石重要辅助基地之一。为了寻找同类型矿床,先后有一些单位对其成因进行了探讨,曾提出岩浆热液脉状矿床、次火山热液矿床、火山熔岩矿床、沉积变质矿床等成因。由于该矿形态复杂,蚀变强烈,确定成因十分困难,争论很多。
Located in Tong’an District, Huili County, Sichuan Province, Xinfa Iron Mine is one of the important auxiliary bases for third-line construction of iron ore with good ore quality, shallow burial and easy mining. In order to find the same kind of ore deposit, some units successively discussed the origin of the deposit, and proposed the origin of magmatic hydrothermal vein deposit, subvolcanic hydrothermal deposit, volcanic lava deposit and sedimentary metamorphic deposit. Due to the complex shape and intense alteration of the ore, it is very difficult to determine its cause and there are many controversies.
