摘要
伊山金铅锌矿位于磁异常边缘的梯度带,航磁垂向一阶导数具有弱磁异常显示,其值为0.5~5n T/km。伊山金铅锌矿航电特征明显,表现早期单峰、晚期双峰且呈北西—北西西向展布的航电异常特征。依据矿体地质特征及其航空电磁异常特征,建立了寻找与伊山相似类型矿床的找矿模型。
The gradient Yishanjin lead-zinc deposit is located in the edge of the magnetic anomaly zone, aeromagnetic vertical derivative with weak magnetic anomalies show that its value is 0.5 ~ 5n T/km. Yishanjin lead-zinc avionics characteristics, manifestations of early and late Shuangfeng and showed a unimodal nw-nww avionics anomaly distribution. Based on the geological characteristics of the ore body and the characteristics of the electromagnetic anomalies, the prospecting model of the similar type deposits in the south of the Yangtze River is established.
