高精度磁法测量在河南橡子庙磁铁矿区的应用

Application of high precision magnetic survey in Xiangzimiao magnetite mine area

河南省卢氏县橡子庙沟铁矿区20世纪已进行过详查,但是矿区东部投入工作很少,未发现具规模的铁矿体或矿化。2006年,在矿区开展高精度磁测扫面后,验证了矿区中部原有的小规模异常,并且还在矿区东部发现多个异常,整个矿区的异常基本分布在同一条带上,均位于瓦穴子断裂南侧,其中"YD4"异常长度800多米,经过异常对比及剖面异常反演,推断是一铁矿体,布置工程验证是近平行发育的矿脉组合,与物探推断结果相吻合。

Last century, the general exploration of Xiaozimiaogou magnetite mine area in Lushi County, Henan Province was finished. However, magnetite bodies and iron mineralization was not discovered in the east part of the mining area due to inadequate work. Prospecting of the Xiaozimiaogou mine area in Lushi County of Henan, conducted by the 5th Geological Team, Henan Provincial Bureau of Non - ferrous Metals Geology and Mineral Resources with the financial support by Department of Land and Resources of Henan Province and Department of Finance of Henan Province, confirmed the existence of small - size anomaly in the central area and discovered several anomaly in the eastern area. All anomalies in the mining area is located in the same belt at the southern side of Waxuezi Fault. Number YD4 anomaly, with a length of 800 meters, is inferred to be an iron mineral belt on the basis of the comparison of anomaly and inversion of section anomaly It is confirmed to be the assembly of parallel veins by engineering, which is identical to the geophysical deduction.
