摘要
杨家桥铁矿是典型的"新余式"沉积-变质磁铁石英岩型矿床,矿体、赋矿地层及围岩之间存在某种物性差异,因而矿体具有明显的地球物理异常特征。结合该矿床的相关地质勘探成果,在分析区域地质背景及矿床地质特征的基础上,首先对矿床所在区域的地球物理特征及矿区地球物理特征进行了分析,然后总结了地质-地球物理找矿标志,并构建了地质-地球物理找矿模型,对于该矿区进一步进行深部找矿有一定的参考价值。
The Yangjiaqiao iron deposit is belongs to the classical ＂ Xinyu type＂ sedimentary-metamorphic magnetite quartzite type deposit,the physical properties difference of the ore-bodies,ore-bearing strata and surrounding rock mass are different with each other,so,the geophysical characteristics of the ore-bodies is significant.Based on some related geological and exploration results of the Yangjiaqiao iron deposit,and the analysis results of the regional geological background and deposit geological characteristics,firstly,the geophysical characteristics of the region where the Yangjiaqiao iron deposit is located and the mining area are analyzed in detail,then,the geological-geophysical prospecting indicators of the mining area are summarized and the geological-geophysical prospecting model of the mining area is also established.The above analysis results related to the geophysical characteristics and prospecting model of the ＂ Xinyu type＂ Yangjiaqiao iron deposit can provide some reference for the further deep prospecting work of the mining area.
