Magnetic Anomaly Characteristics of Gansu Langwashan Iron Deposit and the Relationship with Mineralization
-
摘要: 狼娃山铁矿床地处甘肃北山地区白山—狼娃山航磁异常带，通过对区域地质成矿背景和磁异常特征进行综合研究后，认为该区属于岛弧火山岩成矿区，是寻找火山岩型铁矿有利地带。矿床内强度较高的磁异常集中区均为地表及浅部矿体引起；强度较低的宽缓磁异常是深部隐伏磁性体的反映；环形强磁区中心的弱磁区可能是受周边强磁性影响，仍具有较好的找矿远景。该矿床是甘肃北山地区较重要的铁矿类型，磁异常的解剖研究成果对寻找同类型矿床具有较好的指导作用。Abstract: Langwashan iron deposit is located in the aeromagnetic anomaly zone of Beishan area in Gansu province. Based on the comprehensive study of the regional geological metallogenic background and the characteristics of the magnetic anomaly, it is considered that the iron deposit belongs to the metallogenic island arc volcanic rock, favourable for volcanic iron deposits. The intensive magnetic anomaly areas in the deposit are from the surface or shallow of ore bodies;the wide-and-slow magnetic anomaly is the reflection of the deeply buried magnetic body; the weak magnetic areas in the center of the ring-shaped strong magnetic area, probably influenced by the peripheral strong magnetism, still have good prospecting potential.Langwashan iron deposit is important in Beishan area, hence the results of the magnetic anomalies can guide the exploration of similar deposits.
