| 摘 要： | 以寻找斑岩型金矿为主要找矿方向,利用物性参数测定结果来区分花岗斑岩体与其它地质体的磁性差异。通过磁测结果来推断隐伏花岗斑岩体的埋藏位置及分布范围。并对磁异常主剖面曲线进行了反演,定量推断斑岩体的埋深、产状及具体边界范围。从而为寻找斑岩型金矿主要赋矿地段——花岗斑岩体边缘地带提供了找矿方向。

| Abstract: | This paper mainly introduces the prospecting direction for searching the porphyry gold deposit,using the physical parameters determination results to distinguish the magnetic differences between the granite porphyry and other geologic body.Based on the magnetic survey results,the location and distribution of buried hidden granite porphyry are deduced and the inversion on the main profile curve of the magnetic anomaly is made.The buried depth,occurrence and specific boundary range of the porphyry deposit are deduced quantitatively.Thus it could provide the direction for detecting the main area of the porphyry gold deposit——the boundary of granitic porphyry. |
