摘要
镇江韦岗铁矿是一个已经勘查开发数十年的老矿山,目前保有资源储量保证程度已达严重危机。分析矿区成矿地质条件和矿床特征,铁矿体主要分布在碳酸盐岩层与中酸性侵入岩的接触带上,铁矿体普遍磁性强,且在地表形成一定规模的磁异常,梯度北陡南缓,向南有规则地递减呈梯形散开,说明矿体有一定的延伸。深部已施工的见矿钻孔和井中磁测异常对应,反映矿区深部-200m^-800m找矿前景良好。
Weigang iron mine is an old mine being mined for tens of years and entered into a stage of minimum resources guarantee. Through analyses of ore-forming geological conditions and deposit properties, the authors found the iron ore bodies were mainly distributed in the carbonate layers and the contact zone of medium to acid intrusive rocks, the iron bodies were mostly of strong magnetism, forming magnetic anomaly of a certain scale, with a gradient of steep in the north and gentle in the south, and dispersed southward regularly in trapezoid, revealing a certain extension for the orebody. Through a deep drilling construction, the authors found a corresponding magnetic anomaly in the hole and well, demonstrating a fine prospecting prospect within the depth of -200m to -800m.
