| 中文摘要: |
| 镍是中国关键战略性金属，广泛应用于不锈钢、新能源电池等重要领域。近些年镍资源需求持续增长，资源保障压力日益突出。中国镍资源主要分布在西北地区，中东部相对匮乏，亟须开拓新的找矿区域。本文以安徽歙县伏川—北岸地区为研究区，基于高精度地球物理勘查数据，结合区域地质与岩石地球化学分析，系统识别出该区存在隐伏的含镍超基性岩体。研究结果表明，伏川岩体向东南延伸趋势显著，镍元素含量普遍高于背景值，显示良好的镍富集条件。磁法与瞬变电磁法联合剖面揭示深部存在低阻—高磁综合异常，进一步指示隐伏岩体的存在。综合认为，伏川—北岸地区具有良好的岩浆型镍矿成矿地质条件与资源潜力，建议进一步加强深部勘查工作，以实现该区镍矿找矿新突破。 |
| 英文摘要: |
| Nickel is a crucial strategic metal resource in China, extensively used in stainless steel, alloy manu.facturing, new energy batteries, and other fields. It plays an irreplaceable role in safeguarding national resource se.curity and supporting high-tech industrial development. In recent years, the rapid growth of the new energy vehicle industry has continuously increased the demand for nickel resources, highlighting the pressure on resource supplyassurance. China′s nickel resources are primarily distributed in the northwestern region, while central and easternareas are relatively resource-deficient, making it urgent to conduct exploration in new regions. This study focuseson the Fuchuan-Beian area in Shexian County, Anhui Province. Utilizing high-precision geophysical explorationdata combined with regional geological background and petrochemical analysis, it systematically identifies and in.fers the presence of concealed nickel-bearing ultramafic rock bodies in this area. Results indicate a clear southeast.ward extension trend of the Fuchuan rock body, with nickel content generally exceeding background values, demon.strating favorable nickel enrichment conditions. Integrated magnetic and transient electromagnetic (TEM) profilesfurther reveal low-resistivity and high-magnetic anomalies at depth, indicating the presence of concealed rockmasses. Comprehensive analysis suggests that the Fuchuan-Beian area possesses favorable geological conditionsand resource potential for magmatic nickel deposit formation. It is recommended to intensify deep exploration andengineering verification in this area to achieve new breakthroughs in nickel prospecting. |
