重力测量在云南镇康芦子园铁铅锌铜多金属矿勘查中的应用

Application of gravity survey in the exploration of Luziyuan deposit in Zhenkang area of Yunnan province

云南镇康芦子园铅锌铁多金属矿属于国家整装勘查区域,矿床成因与中酸性岩体关系密切,通过开展矿区及外围重力测量,圈定隐伏中酸性岩体的范围,中酸性岩体与围岩接触带为芦子园夕卡岩型铅锌铁多金属矿床的有利成矿地段.在此基础上,分析已知矿床点与剩余重力异常及磁测、化探异常的关系,并对重磁异常进行反演,有效地指导了找矿工作的部署.

The Luziyuan lead-zinc and iron ore deposit in Zhenkang area is related with the acid rock.By carrying out the gravity survey of the mining area and the periphery,the scope of the concealed acidic rock can be defined,the contact zone between the acidic rock and the surrounding rock is favorable for the formation of the lead-zinc and iron ore deposit.On this basis,by analyzing the relationship between known deposits and residual gravity anomalies and magnetic anomalies,geochemical anomalies and inversion of gravity and magnetic anomalies,to guide the direction for the next mineral search.
