在毛主席光辉哲学思想指导下,1972～1975年,我们在独木—八盘岭间具有低缓磁异常的混合岩中,找到一处铁矿。从此,打开了混合岩中找矿“禁区”的大门,为在鞍本地区找鞍山式铁矿提供了新经验。同时,也为在我国北方前震旦纪古老变质岩系中找矿闯出了新路子。在这个找矿经验的启示下,我们又在老岭和马耳岭的混合岩中发现新矿体,扩大了矿床远景,并在其他地区开辟了混合岩中找矿的新战场。
Under Chairman Mao’s glorious philosophical thought, from 1972 to 1975, we found an iron mine in the mixed rock with low magnetic anomalies between Dakou and Bapanling. Since then, the gate to open the “restricted area” for prospecting in the mixed rock has been opened up, providing new experiences in finding Anshan-type iron ore in the Anshan area. At the same time, it also broke new ground for prospecting in the ancient metamorphic rocks of the former Sinian in our country. Inspired by this prospecting experience, we discovered new ore bodies in the mixed rocks of LaoLing and Malingling, expanded the prospect of the ore deposits and opened new battlefields for prospecting in mixed rocks in other areas.
