Fluvial magnetic susceptibility as a proxy for long‐term variations of mountain permafrost development in the Alp‐Carpathian region

Abstract

susceptibility as a proxy for long-term variations of mountain permafrost development in the Alp-Carpathian region.

Obliquity‐driven mountain permafrost‐related fluvial magnetic susceptibility cycles in the Quaternary mid‐latitude long‐term (2.5 Ma) fluvial Maros Fan in the Pannonian Basin

“…Püspöki et al . 2021b), which is a correlative conformity in the Szarvas and Kevermes sections containing MP6.…”

“…The Viviparus boeckhi biozone is determined by the presence of Viviparus boeckhi Halaváts, 1888, the last appearance datum of which (LADVb) occurs within the Brunhes Epoch in magnetic susceptibility cycle III according to Püspöki et al . (2021b), while its first appearance datum (FADVb) coincides with the Olduvai Subchron. An additionally important chrono‐species occurring in the Viviparus boeckhi biozone is the concurrent Planorbis planorbis f. dentata Krolopp, 1976, which can be identified based on its characteristic fragments.…”

“…Stratigraphical correlation of low‐field magnetic susceptibility records of the reference boreholes of the Maros fluvial fan based on laboratory measurements in comparison with the reference sections in the Körös Basin (Püspöki et al . 2021b) and in the Chinese Loess Plateau (Ding et al . 2005).…”

“…Laboratory measured low‐field susceptibility ( χ LF ) values of the reference boreholes are plotted together with Dévaványa and Szarvas as reference sites representing the Pannonian fluvial succession (Püspöki et al . 2021b) (Fig. 5) and the Jingbian section (Ding et al .…”

“…2016), enable the stratigraphical interpretation of thick fluvial successions, together with their correlations with globally relevant loess and marine proxy records (Püspöki et al . 2021b). To examine these relationships a set of fluvial settings has been investigated in the Pannonian Basin, and it is reasonable to extend the investigation to fluvial fans that are so frequent in mid‐latitude mountainous regions.…”
