云南大理至瑞丽铁路西段的潞西盆地含水层结构复杂、温泉甚多。选择该盆地的典型温泉——法帕温泉和芒留温泉,针对该区温泉成因分析中存在的疑点问题开展了地质、水文地质和水文地球化学调查工作。在分析该区温泉的水文地球化学特征,并与不同条件的温泉作类比研究的基础上,进一步剖析了温泉的成因。研究结果表明,法帕温泉和芒留温泉为典型的断裂型温泉,接受大气降水补给,下渗后被断层中的高温内生流体加热并在断层中储集和运移,储热层均为灰岩、白云质灰岩及泥灰岩,热储深度为2000m左右,温度可达160℃左右。 相似文献

重庆市东温泉是以三叠系嘉陵江组灰岩为热储层,以三叠系上统须家河组和侏罗系红色砂泥岩地层为盖层,以三叠系飞仙关组砂页岩为下部隔热层的层状深循环型地热系统。本文从地热显示、水文地球化学、热储结构及热水动态变化等方面分析了该市东温泉地热地质特征,并从热源及补径排条件等方面探讨了东温泉成因模式。结果可知:东温泉区共有天然温泉11处,人工钻井温泉6处,水温27℃~53℃,水质类型为SO4-Ca型,地热水热源主要来自地热增温,地热水补给源于大气降水。其成因模式主要为:大气降水在桃子荡背斜槽谷的灰岩出露区下渗形成浅层地下水,部分浅层地下水顺灰岩岩层的孔隙裂隙向深部运移,同时地热水顺构造线方向由南向北径流,在运移过程中不断溶解和富集矿物盐及微量元素,并以传导型的地热增温方式提高深部循环水的温度,在五布河流深切峡谷地段出露成泉,或以人工钻井形式排泄。研究结果对今后该区地热资源的合理开采及温泉开发远景规划等具有一定的指导意义。 相似文献

结合马岔河区域内多年的水质分析、监测资料,系统阐述了马岔河温泉水文地球化学特征,利用同位素手段,分析了马岔河温泉的水源、补给区高程;利用Na-K-Mg三角图解法判断水岩平衡状态,判断结果为马岔河温泉属于未成熟水,只能利用SiO2温标计算温泉的热浩温度。通过分析,认为其水源为大气降水,热源为深循环加热,热储温度72.33℃,热储深度为2690m。马岔河温泉的地质成因为:在正常区域地热场环境中,大气降水沿高渗透率的岩石渗入地下,深部地下水沿断层破碎带向马岔河运移,循环加热,深部地下水在马岔河断束上涌汇集,并与近源低温地下水混合,在地势低洼处出露形成温泉。 相似文献

长白山仙人桥温泉是我国著名的矿泉水疗养旅游胜地,阐明其成因模式对于温泉区的进一步开发和热水资源的可持续利用具有一定的指导意义。笔者采用地质学、水文地质学和地球物理学结合的方法对其进行了系统研究。结果表明,该区属中低温对流型地热系统,地热成因模式为断裂岩溶复合型。热储层主要为古生界寒武系和奥陶系灰岩,灰岩本身的孔渗条件较差,但后期发育的构造裂缝和溶蚀裂缝却极大地改善了热储层的储集性能;盖层主要为中生界侏罗系安山岩和安山质火山碎屑岩,封闭性较好。长白山一带的大气降水沿侧向断裂和溶蚀裂缝渗入热储层中成为地下水;然后经正常大地热流加热成为地热水,热储温度为89~118℃,循环深度为2 853~3 820m;最终地热水在区内NE向与NW向断裂交汇处富集并沿导水断裂上涌形成温泉。因此,该区断裂交汇和岩溶发育的部位是地热勘探的有利部位。该结论为该区类似地热资源的勘探提供了理论依据。 相似文献

息烽温泉为贵州百年名泉,通过收集整理多年水质分析资料,系统阐述了温泉水文地球化学特征;采用同位素化学方法,分析了温泉补给来源、形成年龄及高程效应;利用Na-K-Mg三角图解判断温泉水属未成熟水,采用Si02地热温标法估算出温泉热储温度为101.92℃,热流体循环深度超过2 500m;在综合分析基础上,提出息烽温泉地热水循环于洋水背斜西翼深埋藏于地下的震旦系上统灯影组Zbdn、板溪群清水江组Ptbnbq地层中,热流体从南西向北东径流,在息烽温泉处受F1断裂阻隔而沿断层带上升,在"低势点"出露成泉的地质成因模式。 相似文献

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ1 roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
