摘要
狼娃山铁矿属于岩浆岩型磁铁矿床,预测类型为矽卡岩型,矿床规模为中型。为了找寻狼娃山地质—地球物理成矿模型,首先可根据航磁异常划分出地层、岩性、构造等地质单元;然后选择成矿有利部位开展高精度地磁测量,寻找和圈定矿致异常;最后通过分析研究该测区的地质地球物理特征,找出了狼娃山简要的成矿模型。结果表明,通过对地质—地球物理资料的分析来为矿区周围找矿方向提供地质—地球物理成矿模式是可行的。
The Langwashan ironore belongs to magmatic rock typy deposit. The predication type is skam deposit and the deposit scale is middle-sized. In order to find the Langwashan geological-geophysical modeling, firstly we divided the geological units such as stratum, lithology, structure based on aeromagnetic anomalies. Then we selected the metallogenetic prospective area of high-precision magnetic measurement to find anomalies related to mineralization. Finally we found out the metallogenic model for Langwashan. It turns out that it is feasible to provide geological-geophysical model for prospecting the mining area nearby through the analysis of geological and geophysical data of the area.
