External and Internal Undersurface Features Produced by Subaerial Deposition of Pyroclastic Material on a Soil Profile: NOTES

P. A. Riezebos

ABSTRACT

Late Pleistocene pyroclastics, ejected from the Meerfelder maar in the western Eifel, are underlain by a podsol profile developed in coarse sand. The undersurface of the very first volcanic layer shows an irregular pattern of globular and lobate mounds separated by differently formed depressions. The internal structure is characterized by an uneven textural distribution. It is thought that the observed features point to an initial deposition of a hot muddy mass of low viscosity.
