罗河铁矿是庐枞火山岩地区的一个大型铁矿床,呈水平“层带状”隐伏于地下深处。 1976—1978年铁矿地质会战期间,不少生产教学科研单位,对其物质组分、成因类型、矿体展布等多方面进行了研究。对其控矿构造也都提出了各自的见解,归纳起来,大体有两种意见:(1)强调控矿构造与次火山岩体有关。由于与成矿有关的次火山岩体的冷凝退缩,而产生的虚脱塌陷、岩体隐蔽爆破以及岩体原生节理等,提供了铁矿充填的空间。
Luohe iron ore is a large iron ore deposit in Luzong volcanic area, which is in a horizontal “zonal” state hidden in the depths of the underground. During the iron ore geology battle from 1976 to 1978, quite a few teaching and research units were produced, and their material components, types of genesis, distribution of ore bodies and so on were studied in many aspects. Their control structures are also put forward their own opinions, summed up, there are generally two views: (1) stressed that the ore-control structure and subvolcanic rock mass. Due to the condensing and shrinking of subvolcanic rock mass related to metallogenesis, the collapsed collapse, the concealed rock mass blasting and the primary joints of the rock mass provide the space for iron ore filling.
