| 摘 要： | 里竹山铁矿赋存在马邓岩群外麦地岩组中,成矿与区内基性火山岩(玄武岩)相关,矿石与围岩均具有相似特征。后期热变质作用、叠加改造作用并未完全改变其原岩结构构造特征,属于构造和海底基性火山喷发有关的沉积变质型磁铁矿床。

| Abstract: | The Lizhushan Fe deposit exists in the Waimaidi lithostratigraphic formation of Palaeozoic Madeng lithostratigraphic group.The metallogenesis is related with the basic volcanic rock(basalt)in this area.The characteristics of ore are similar to those of the wall rock.The later thermal metamorphism doesn’t completely reform the texture and structure characteristics of original rock.It belongs to the sedimentary metamorphic magnetite deposit related with the structure and submarine basic volcanic eruption. |
