利国铁矿是怎样找到隐伏矿床的

How Did the Concealed Ore Bodies of the Liguo Iron Mine Are Found?

利国铁矿是一个中型磁性富铁矿床.日伪时期即已开采.50年代恢复生产.先以就矿找矿、探边摸底的方法寻找浅部矿体.60年代在成矿有利部位及高磁异常区找矿,使储量增长数倍.70年代验证低缓磁异常,向深部找矿.后来又采用地质与物探方法相结合,在矿区外围发现了矿床.作者认为,这里仍有找矿前景.

The Liguo Iron Mine, being medium in size, is characterized by high grade magnetic iron ores. Itwas opened in the period of Japanese occupation. In the fifties, iron ore production was progressivelyresumed and developed, with some shallow burial ore bodies found by prospecting along both the hanging and foot walls of the known ore body and at its bottom. In the sixties prospecting program wascarried out in favourable places for mineralization and high-intensity magnetic anomalous areas. Manyore bodies were discovered and the ore reserves had doubled and redoubled. During the seventies,prospecting work was mainly confined to test the gentle magnetic anomalous areas in order to try tofind deeply buried ore bodies. Later on by a method of combining geology with geophysics some newore bodies were discovered in the peripheral area of the known deposit. The author believes that theperipheral area has still more prospects in iron ore exploration.
