摘要
矿区位于福建省大田汤泉-龙岩马坑重要铁矿成矿集中区边部,是中国东南部重要成矿集中区。在地质构造演化过程中,形成了以晚古生代准地台型细碎屑岩—碳酸盐岩地层出露广泛。本文主要通过近些年来对矿区一些工作经验和认识,简要分析矿区的地质与成矿、构造与成矿、岩浆与成矿等之间的关系以及主要矿体与伴共生矿体间的关系,认为矿床具有多成因类型相叠加,成矿具有多期次、多成因特征,铁矿床的形成应早于铅锌,且具有沉积改造特征,铅锌矿床则具有矽卡岩成矿特征。
The mining area is located at the edge of the important ore-forming concentration area of Tangquan longyanmakeng in Datian,Fujian Province,and is an important ore-forming concentration area in Southeast China.In the process of geological structure evolution,the late Paleozoic quasi platform type fine clastic rock carbonate rock strata are widely exposed.In this paper,based on some working experience and knowledge in recent years,the relationship between geology and mineralization,structure and mineralization,magma and mineralization,and the relationship between main ore bodies and paragenetic ore bodies in the mining area are briefly analyzed.It is considered that the ore deposits have the characteristics of multi genetic type superposition,multi-stage and multi genetic mineralization,and the formation of iron deposits should be earlier than that of lead and zinc,and they have sedimentation The lead-zinc deposits have the characteristics of skarn mineralization.
