摘要
为了深入挖掘找矿潜力,以垂向二阶导数为主要手段对临湘多金属成矿区重力异常地质成因进行了重新认识,推断了研究区构造格架及隐伏岩体分布情况,总结了已知矿点(体)与重力异常、隐伏岩体、断裂构造之间的关系,得出研究区仍存在寻找大型以上多金属矿潜力的结论,为深部找矿预测提供了重要的地球物理依据。
Re-understanding of the gravity anomaly of the Linxiang polymetallic ore-forming area in northeastern Hunan Province and its geodynamic mechanism was obtained mainly by means of vertical second derivative.The authors inferred the distribution of the structural framework and the concealed rock bodies of the study area,summarized the relationship between the gravity anomalies,the concealed rock bodies and the fracture structures in the known ore spots（ore bodies）.It is concluded that there still exists the potential of finding large polymetallic deposits.The results obtained by the authors provide important geophysical evidence for deep ore prognosis.
