| 摘 要： | 四川盆地海相三叠系是四川探盐找钾的重要层位。通过地质背景的分析，盐类保存、水动力条件和水化学特征在不同水文地质区表现不一，反映在异常水型也极不一致。利用异常水点离子的比例系数在海水浓缩曲线图上的落点位置，判别水点成因类型，从而发现盆地东北宣汉、盆地西部平落和盆地东部万县向斜周边背斜水点具含钾溶滤水特征，值得重视和进一步探索。

| Abstract: | The marine Triassic sequence of Sichuan basin stands as a key target for searching for salt andpotassium resources in Sichuan province. In the light of the basin's geological settings, one Place isdifferent from another in salt preservation, hydrodynamic conditions and hydrochemicalcharacteristics more important, in types of anomalous groundwaters. What genetic type an anomalousgroundwater holds is mainly based on what coitions of a concentrational curve for normal sea waterits ion ratio coefficient will fall on. home anomalous groundwater sites featuring a SOluble potassium-containing solution were mapped by deciding the types, around three synclinets: Xuanhan at thenortheastern part of the basin, Pingluo at the western and Wanxian at the eastern, deserving ouraddressing and further studying. |
