【摘要】 本文采集并分析了甘肃东部地区9个温泉的化学成分及热焓分布,分别讨论了氦及其同位素比值He³/He⁴、微量元素组分F^-、Cl^-、Li⁺的含量以及He⁴/Ar⁴⁰值的变化。上述各项指标在秦安地区出现了同步异常。最后,应用因子分析方法综合分析了变量与样品的信息变化,结果表明在秦安—清水—带可能有一隐伏断裂,并伴有岩浆挤入。更多还原

【Abstract】 Nine samples of hot springs covering the eastern region of Gansu Province are collected and analysed. The measured components include He, He³/He⁴, F^-, Cl^-, Li⁺, He⁴/Ar⁴⁰ etc.. These items present synchronous anomalies in Qin’an region. Finally, by using a method of factor analysis, the information variation of the samples and components is comprehensively analysed. The result shows that it is possible to exist a buried fault in company with magmatic intrusion in Qin’an-Qingshui region.更多还原
