通过地面高精度磁法测量,在研究区圈定了商C-1至商C-8八个规模大、强度高的地磁异常,在对它们的场源性质、深度、规模、形状等特征深入研究解析的基础上,在商C-1和商C-6异常上分别布设了地面高精度磁法、地面高精度重力、可控源音频大地电磁测深(CSAMT)综合物探剖面做重点研究,并根据综合剖面异常推断解释成果分别布置ZK01和ZK03孔予以钻探并辅以综合测井验证,结果在ZK01孔发现了太古界太华群的巨厚磁性矿化层,在ZK03孔中发现了9层铁矿体或矿化体。
通過地麵高精度磁法測量,在研究區圈定瞭商C-1至商C-8八箇規模大、彊度高的地磁異常,在對它們的場源性質、深度、規模、形狀等特徵深入研究解析的基礎上,在商C-1和商C-6異常上分彆佈設瞭地麵高精度磁法、地麵高精度重力、可控源音頻大地電磁測深(CSAMT)綜閤物探剖麵做重點研究,併根據綜閤剖麵異常推斷解釋成果分彆佈置ZK01和ZK03孔予以鑽探併輔以綜閤測井驗證,結果在ZK01孔髮現瞭太古界太華群的巨厚磁性礦化層,在ZK03孔中髮現瞭9層鐵礦體或礦化體。

Through the ground precision magnetic survey measurements,we found eight magnetic anomalies named from ShangC-1 to ShangC-8,their size and strength is all different. Based on further study on the nature,depth, size,shape and other characteristics of their field source,we researched focus on the integrated geophysical profiles which contain the ground precision magnetic method,precision ground gravity,controlled source audio magneto-telluric(CSAMT)sounding method,and arranged ZK01 and ZK02 hole to be drilled and supplemented by integrated logging verification according to the results of inference and interpretation of the integrated profile anomalies. Finally,we found thick mineralized magnetic layer in the ZK01 hole and nine magnetite ore bodes or mineralized iron bodes in the ZK03 holein Archean Taihua Group.
