Article
This work aims to introduce and test various semiquantitative field methods and environmental magnetic measurements to help prepare future planetary missions on Mars. For analog observations, paleosols of loess successions in various stages of soil development were investigated and were used as models to infer environmental change during environmen...

The geomorphological characteristics of the loess succession at Malá nad Hronom (Slovakia) mean that it provides a valuable opportunity for the investigation of differences in soil formation in various topographic positions. Along with the semiquantitative characterization of the paleosols (on the basis of physical properties, texture, the characte...
Article
Diffuse Reflectance Spectroscopy (DRS) is a rapid, relatively new method in Quaternary research to analyse sediments and paleosols. This method takes into account clay mineral content, amount of Fe-bearing minerals and grain size composition of samples, simultaneously. Different Quaternary sediment samples were chosen forcharacterization and compar...
Article
Diffuse reflectance spectroscopy (DRS) parameters, such as the redness index and hematite/goethite ratios are popular in the study of loess-paleosol sequences. The suggested parameters, however, have their limitations: only some parts of the whole reflectance spectrum are being used, and the spectra of some important components may be excluded from...
Article
On the basis of a key model of the appearance of hematite and goethite in some Chinese and European loess successions, paleosols generally contain higher proportions of hematite formed by pedogenic processes during warm and humid interglacials, while loess contains sedimentary goethite deposited during colder, glacial periods. Rock magnetic measure...
Article
A multi-proxy analysis, including grain size, magnetic susceptibility and the examination of stable isotopes of hypocoatings, was performed on the loess-paleosol succession at Hévízgyörk (Hungary). Field investigations suggested a continuous record of sedimentation and pedogenesis. However, after the identification of the Bag Tephra, it revealed th...

A multi-proxy analysis was performed on the loess-paleosol succession in Hévízgyörk (Hungary), which included grain size analysis, magnetic susceptibility, diffuse reflectance, micromorphology and the examination of stable isotopes from hypocoatings. Field investigations showed a continuous record of sedimentation and pedogenesis over the course of...
Conference Paper
Full-text available
An accurate picture of the spatial distribution of stable isotopes of modern precipitation is a crucial requirement for many hydrological, ecological, and paleoclimatological applications. The aim of our research is to develop a gridded data set consisting of monthly stable oxygen isotope composition of precipitation (δ18Op) for Hungary and the adj...

An accurate picture of the spatial distribution of water stable isotopes of modern precipitation is a crucial prerequisite for many hydrological, ecological and paleoclimatological applications. The main aim of our research is to develop a gridded data set of monthly stable oxygen isotope composition of precipitation (δ 18 O p) for the Alps and the...
