Onderzoekingen betreffende de loessgronden van Zuid-Limburg

Research output: Thesisinternal PhD, WU


There were two hypotheses on the formation of loessoid soils in south Limburg. F. H. van Rummelen and W. J. Jongmans explained the origin by weathering of underlying rocks and reworking of the weathered material by water; J. H. Druif concluded on qualitative mineral data that the soil material was wind-borne from the north.

Detailed descriptions of places and sample profiles, and quantitative data on heavy minerals and grain size confirmed the hypothesis of Druif. The mineral associations of loess soils were similar to those of glacial deposits in the central and northern parts of the Netherlands and deviated considerably from those of the underlying rocks. The grain size was characteristic for loess.

At least two deposits were present: the oldest, possibly of Riss age and the younger Wnrmian.
