Abstract

Morphometric analysis is frequently used for the assessment of neotectonic/young tectonic movements. The analysis consists of several methods that, in some cases, may yield different results. We used six morphometric methods to evaluate 42 river/creek catchment areas comprising the Spišská Magura region and adjacent parts of the Belianske Tatry Mts. Each method evaluated the possible influence of tectonics on topography numerically (by parameters). The integration of the mean parameter values was used to obtain the relative tectonic activity index (Iat), based on which we determined the role of the tectonic activity in the evolution of each analyzed catchment area. A comparison of the integrated map of relative tectonic activity with the known tectonic lines shows the little match in the Spišská Magura region. This is especially valid for the areas along with a striking Subtatric-Ružbachy fault system (SRFS) that is assumed to be active in the late Pleistocene and where morphometric criteria only show little tectonic activity. In contrast, the parameters provided by some individual methods used for the integrated map of the relative tectonic activity indicate a good match with known tectonic lines. For example, the basin shape ratio and mountain front sinuosity suggest high tectonic activity along the border of the Spišská Magura region and the Pieniny Klippen Belt, which is also indicated in geological maps. The evaluation of U- versus V-shaped valleys (Vf index) shows more intensive uplift of the areas of the Belianske Tatry Mts. compared to the areas within the Spišská Magura region, which is also expected from the geological maps and other studies. The evaluation of individual morphometric parameters and the parameter obtained by their integration implies the necessity to use several morphometric methods for a more reliable assessment of the role of tectonics in the evolution of studied areas.

形态计量分析作为解释构造活动的工具：SpišskáMagura和Tatry Mts.，西喀尔巴阡山脉

形态计量分析经常用于评估新构造/年轻构造运动。该分析由几种方法组成，在某些情况下可能会产生不同的结果。我们使用了六种形态测量方法来评估42个河流/小溪集水区，包括SpišskáMagura地区和Belianske Tatry Mts的邻近地区。每种方法都用数值（通过参数）评估了构造对地形的可能影响。平均参数值的积分用于获得相对构造活动指数（Iat），在此基础上，我们确定了构造活动在每个分析集水区演变中的作用。将相对构造活动的综合地图与已知的构造线进行比较，可以看出SpišskáMagura地区几乎没有匹配。这对于具有引人注目的Ružbachy地下断层系统（SRFS）的地区尤其有效，该断层系统被认为在更新世晚期活动，形态测量标准只显示出很少的构造活动。相反，用于相对构造活动的综合图的一些单独方法提供的参数表明与已知构造线很好地匹配。例如，盆地形状比和山前弯曲度表明，SpišskáMagura地区和Pieniny Klippen带边界沿线的构造活动很高，地质图中也显示了这一点。U型与V型山谷（Vf指数）的评估显示，与SpišskáMagura地区相比，Belianske Tatry Mts地区的隆起更加强烈，这也是地质图和其他研究所预期的。对单个形态计量参数及其整合获得的参数的评估意味着有必要使用几种形态计量方法来更可靠地评估构造在研究区域演变中的作用。

期刊介绍： Acta Montanistica Slovaca publishes high quality articles on basic and applied research in the following fields: geology and geological survey; mining; Earth resources; underground engineering and geotechnics; mining mechanization, mining transport, deep hole drilling; ecotechnology and mineralurgy; process control, automation and applied informatics in raw materials extraction, utilization and processing; other similar fields. Acta Montanistica Slovaca is the only scientific journal of this kind in Central, Eastern and South Eastern Europe. The submitted manuscripts should contribute significantly to the international literature, even if the focus can be regional. Manuscripts should cite the extant and relevant international literature, should clearly state what the wider contribution is (e.g. a novel discovery, application of a new technique or methodology, application of an existing methodology to a new problem), and should discuss the importance of the work in the international context.
