摘要

在北钙质阿尔卑斯山脉(NCA),有无数的小湖泊,它们的地理集水区很小,通常位于各自峰顶区域的略下方。一方面,这些湖泊位于岩溶含水层中,它们的存在可能与岩溶作用有关。然后,它们有望与喀斯特水体直接相连。这些湖泊被归类为喀斯特湖泊。另一方面,高山环境也受到冰川作用的影响,湖泊可能与冰川侵蚀和沉积有关。对于这些冰湖,即使在高渗透性岩溶岩性中,地下水流入和流出的份额也被认为是次要的。在这里,我们比较了萨尔斯堡NCA地区可能不同起源的两个高山湖泊,目的是为NCA地区众多小型高山湖泊的航空调查提供基础,并利用这里阐述的指导参数对其进行表征。我们考虑了(a)湖泊的几何形状,(b)潜在的流入和流出系统,以及(c)位于Fuschlsee地区的Filblingsee和Eibensee的物理化学参数和水化学。Filblingsee最初被认为是一个典型的喀斯特湖,而Eibensee被认为是一个冰碛冰坝冰湖。湖泊的几何形状存在明显的差异,喀斯特湖的湖面呈近圆形,深度呈同心剖面,而冰湖在冰川流动方向呈细长状,最深的区域位于冰碛垄的上游。这两个湖的表面流入很少,甚至没有。在这两种情况下,流入和流出都发生在地下水中,但与高渗透性岩溶系统没有直接联系。两湖野外参数的深度剖面差异不大,均表现为中深区地下水流入为主,湖底无水流通过。两个湖泊的水化学及其潜在流出量在溶液负荷方面对应于各自的含水层。Filblingsee的特点是在一个次生封闭的白云线上的一个悬湖,Eibensee位于一个冰川开挖的洼地,被冰川沉积物封闭。虽然两个湖的流入和流出条件以及水化学非常相似,但湖泊的几何形状是一个明显的区别特征,这可以归因于两个湖的不同成因。因此,这可以作为NCA众多小高山湖泊分类的指导参数。

Hydrogeology of alpine lakes in the Northern Calcareous Alps: a comparative study on the role of groundwater in Filblingsee and Eibensee
Abstract In the Northern Calcareous Alps (NCA) there are countless small lakes with small orographic catchments that are often located only slightly below the respective summit regions. On the one hand, the lakes are located in karstable aquifers and their existence is likely to be related to karstification. Then, they are expected to be directly connected to the karst water body. These lakes are classified as karst lakes. On the other hand, the alpine environment is also influenced by glacial processes and lakes might be related to glacial erosion and deposition. For these glacial lakes, the share of groundwater inflow and outflow is regarded as subordinate even within high permeable karst lithologies. Here we compare two alpine lakes of potentially different origin in the NCA in Salzburg with the aim to provide a basis for an aerial survey of the numerous small alpine lakes in the NCA region and their characterization using the guiding parameters elaborated here. We consider (a) the lake geometry, (b) potential inflow and outflow systems, and (c) physicochemical parameters and hydrochemistry of the Filblingsee and the Eibensee, both located in the Fuschlsee region. Filblingsee was initially considered as a typical karst lake and Eibensee as a moraine-dammed glacial lake. Some clear differences arise in lake geometry, which in the karst lake shows a nearly round surface and concentric depth profile, while the glacial lake is elongated in the direction of glacier flow and has the deepest areas just upstream of the moraine dam. Both lakes show very little to no surficial inflow. Inflow and outflow occur in groundwater in both cases but are not directly tied to a highly permeable karst system. The depth profiles of the field parameters of the two lakes differ only slightly and show a dominant groundwater inflow in mid-depth regions but no flow through at the lake bottom. Water chemistry in both lakes and their potential outflows correspond to the respective aquifer in terms of solution load. Filblingsee can be characterized as a hanging lake in a secondarily sealed doline, Eibensee lies in a glacially excavated depression sealed by glacial sediments. While the inflow and outflow conditions and the hydrochemistry of both lakes are very similar, the lake geometry is a clear distinguishing feature that can be attributed to the different genesis of the two lakes. This can therefore be used as a guiding parameter for the classification of the numerous small alpine lakes in the NCA.

期刊介绍: AUSTRIAN JOURNAL OF EARTH SCIENCES is the official journal of the Austrian Geological, Mineralogical and Palaeontological Societies, hosted by a country that is famous for its spectacular mountains that are the birthplace for many geological and mineralogical concepts in modern Earth science. AUSTRIAN JOURNAL OF EARTH SCIENCE focuses on all aspects relevant to the geosciences of the Alps, Bohemian Massif and surrounding areas. Contributions on other regions are welcome if they embed their findings into a conceptual framework that relates the contribution to Alpine-type orogens and Alpine regions in general, and are thus relevant to an international audience. Contributions are subject to peer review and editorial control according to SCI guidelines to ensure that the required standard of scientific excellence is maintained.
