摘要
福建大田高星铁矿位于龙岩马坑—大田汤泉铁矿成矿带的北部,矿体受经畲组制约,呈层状或似层状,是在晚古生代铁矿建造的基础上,经过中生代岩浆作用改造形成的铁矿床,是典型的沉积-改造型矿床。该矿床的主要成矿要素有构造位置、含矿建造、侵入岩和矿化蚀变等,据此建立了成矿模式;在有利成矿地质条件,包括含矿建造与成矿岩体的有利配合、矿体及矿化蚀变分布,叠加物化探异常等预测要素后,建立了预测模型。对在闽西南地区寻找同类型的铁多金属矿具有借鉴意义。
Datian Gaoxing iron deposit of Fujian is the belongs to the northern part of Longyan Makeng--Datian Tangquan metallogenic belt of iron ore. Ore bodies are controlled by Jing- she formation, layered or similar. Based on the late Paleozoic iron ore formation, the iron deposit formed by the transformation of Mesozoic magmatism. It is a typical sedimentary re- formed type iron deposit. The main ore forming elements of the deposit are structural loca- tion, ore bearing formation, intrusive rock and mineralization alteration and so on. The met- allogenic model was established. In favorable geological conditions, including the favorable combination of ore bearing formation and mineralization, distribution of ore bodies and min- eralization alteration, superposition of geophysical and geochemical anomalies, its forecast model is established. These results can be used for reference in the same type of iron poly- metallic deposits in sotlthwestern Fuiian Province.
