| 中文摘要: |
| 河南省七峪潭沟铁矿位于华北地台南缘、熊耳山变质核杂岩构造北侧,区内已发现多条磁铁矿体。文章在矿区成矿地质背景、矿体地质特征及岩(矿)石磁性分析的基础上,运用小波多尺度分析方法对高精度磁测异常进行了研究,得到以下认识:(1)七峪潭沟铁矿矿体主要赋存于太古宇太华群石板沟组黑云斜长片麻岩地层中；(2)七峪潭沟铁矿区内高精度磁测异常特征鲜明,无论从广度和深度上均具有良好的找矿远景。 |
| 英文摘要: |
| The Qiyutangou iron deposit is located in the southern margin of the North China Platform, and the northern Xiong’ershan metamorphic core complex structure, several iron orebodies have been found. On the analysis of the metallogenic background, the geological characteristics of orebodies and the magnetism of country rock and ore in this region, the high precision magnetic anomalies were analyzed by the wavelet and multi-scales decomposition method in this paper. It is concluded that:(1) the iron orebodies mainly occur within the biotite plagioclase gneiss of Shibangou Formation of Achaean Taihua Group； (2) the high-precision magnetic anomalies in the deposit area indicate that there are great potential for further discovery in this region from the distribution depth and extents of the anomalies. |
