This paper presents an outline of lithologic and morphologic developments in the alluvial environment of the Mark Basin in Central Belgium during Post Glacial times. By means of about 900 borings the spatial arrangement and stratigraphic position
of palaeomorphologic features and sedimentary units in different parts of the basin was reconstructed. This, together with the radiocarbon datings, offers an insight into Holocene palaeohydrologic conditions in the Mark River floodplain. The influence of prevailing
Litter marks indicating infiltration area of stemflow-induced water
The AA. found out litter marks around the tree bases, which have the shape like circle. These litter marks seem to be caused by the infiltration excess overland flow due to higher intensity of stemflow than the infiltration capacity of surface soil
. It is suggested that the litter marks can be a useful indicator to estimate the infiltration area of stemflow-induced water.
The valley of the river Mark (Belgium) is filled with deposits of fluvial and aeolian origin accumulated during the Pleniglacial or the beginning of the Late Glacial, not later than 12.000 yr BP. The aim of the investigations was to determine those
The interpretation of soil marks on aerial photographs recorded over the Famenne (Belgium) natural region
Soil marks are closely related to small differences in soil depth and stoniness. Therefore they are valuable for a more appropriate interpolation between sample points in order to delimit soil boundaries. Soil moisture is not directly connected
to the contrast of the soil marks on the image, although it has been a factor causing growth differences of the vegetation. (LW).
Un programme de sondage dans la plaine d'inondation de la rivière Mark a révélé un système fluvial fossile important, encaissé dans des sables fluviatiles probablement d'âge pléniglaciaire et recouvert de matériel éolien. Les conséquences
Sedimentary sequences from three adjacent hollows in northern Lesotho are described. Marked changes in the sediments between 5000 BP and 900 BP indicate climatic changes in the late Quaternary Period. - (AJC)

La morphogenèse des ripple-marks sous-marines est mise en relation avec les ripple-marks dunaires. L'A. distingue trois formes: 1) des ripple-marks symétriques de mer profondes dues aux trajectoires elliptiques des masses d'eau où les sédiments
restent sur place| 2) des ripple-marks dissymétriques dues à la saltation et à la suspension des sédiments en mers très peu profondes à la montée de la marée| 3) des ripple-marks dissymétriques dus à la marée descendante.
Holocene key-marker tephra layers in Kamchatka, Russia
This paper presents the first detailed account of most Holocene key-marker ash layers in Kamchatka, which form a detailed timescale for its stratigraphy. The dated tephra layers provide a record of the most voluminous explosive events from 11
