摘要
石棚子铁矿产于新太古宙鞍山群石棚子组中,铁矿层与围岩呈整合接触。矿床成因类型为变质铁硅建造型(鞍山式)铁矿床。从铁矿成矿地质特征、矿床成因入手,分析铁矿床形成的主要地质因素、矿床形成的地质作用,阐明找矿标志,对比已知矿体与磁异常带之间的关系、预测区内成矿远景。
Shipengzi iron deposit is hosted in the Shipengzi Formation of the Neoarchean Anshan Group,in which the ore layer and surrounding rock are in conformable contact relationship.The deposit genesis belongs to the metamorphic iron-silicon formation deposit(Anshan type).On respect of the geological characteristics and deposit genesis,this paper has analyzed the main geological factors of iron deposit formation,the geological process of deposit formation,the prospecting criteria,and the relationship between magnetic anomaly zones and known orebodies.The metallogenic prospect is also predicted for the working area.
