| 中文摘要: |
| 利用矿床发现勘查史资料，简要列述了甘肃一些重要黑色、有色、贵金属以及稀有金属矿床所开展的主要物化探工作及其物化探异常特征，分析评述了不同类型金属矿床所开展物化探工作的特点和物化探异常的特点，进而分析评述了物化探工作在矿床发现勘查过程中所发挥的重要作用，对甘肃物化探异常筛选、评价和查证工作具有借鉴意义。认为铁矿或个别有色金属矿区的找矿勘查中，磁法工作可发挥直接或间接的作用;电法工作可为有色金属矿区的工作部署和矿体的发现勘查提供间接依据;金矿或一些有色金属矿产的找矿勘查中，化探工作对浓缩找矿靶区往往可发挥不可替代的作用，金异常的内、中带可直接指示矿带的展布，并为探矿工程布置提供直接依据。 |
| 英文摘要: |
| Based on historical data from deposit discovery and exploration in Gansu Province, this studybriefly outlines the main geophysical and geochemical exploration methods applied to key ferrous, non-ferrous,precious metal, and rare metal deposits, along with their associated anomaly characteristics. It then reviews andanalyzes the exploration and anomaly patterns across different deposit types. The analysis confirms the criticalrole of these methods in mineral discovery and exploration. Specifically, magnetic surveys can provide direct orindirect guidance in exploring iron ore and certain non-ferrous metal deposits. Electrical methods offer indirectevidence for designing exploration programs and locating ore bodies in non-ferrous metal deposits. Geochemicalexploration plays an indispensable role in targeting gold and some non-ferrous minerals, where anomalies in theinner and intermediate zones can directly delineate ore belts and guide the placement of exploration engineering. |
