摘要
为了探明矿区矿体的基本形态及其延伸变化情况,在系统搜集和研究前人地质成果资料的基础上,利用地面高精度磁法进行探测,通过对本次磁测数据的分析与处理及剖面反演与钻探验证,结果表明:矿区中西部存在的CT-4异常区为矿致异常,异常体埋深较深,产状较为平缓,CT-1异常区见褐铁矿化,异常体埋深相对较浅,CT-2和CT-3异常区未见明显的褐铁矿化和找矿标志。采用人机交互反演拟合磁性体的形态,通过钻探施工验证,吻合较好。
In order to explore the basic form of orebody and the extension of the changes, based on the collection and study of previous geological data, detect the ground high precision magnetic method, through the analysis and processing of the profile and the magnetic data and drilling verification. The results show that the CT-4 anomaly is caused by ore mining in the Midwest and the abnormal body is buried deep with relatively gentle occurrence. Brown iron mineralization is found in the CT-1 anomaly area and the anomalous depth is relatively shallow. The CT- 2 and CT-3 anomalous areas have no obvious brown iron mineralization and prospecting marks. The shape of magnetic body is reconstructed by using human machine interaction, and is verified by drilling.
