Ferruginous sandstone for building-stone in and round the Hageland
Ferruginous sandstone has locally been used extensively in mostly late-medieval religious and civilian architecture. An inventory of recognizable exploitation sites is presented. Genesis and related characteristics of the different types of building

Spatial distribution of the parent materials, color, clay-eluviated horizon thickness, textural profile type, presence and position of the ferruginous nodules and ferricretes in the profile are analyzed at a small scale using the thematic

Ferruginous weathering under cool temperate climates during the late Pleistocene in southeastern Australia

with ferruginous duricrusts. During the Quaternary, some ferruginous duricrusts have again been formed in some areas. The landforms are higher and more rugged in South-West Africa (Namibia). But the old surfaces and the glacis have always calcareous crusts

In this paper the geochemical processes underlying the formation of ferruginous, residual laterites sensu stricto are compared with the specific processes controlling the formation of highly aluminous varieties, i.e. bauxites. The laterite sensu

IN WESTERN AND SOUTHWESTERN FRANCE THERE ARE TWO TYPES OF DURICRUSTS: FERRUGINOUS LATERITE AND SILCRETE. WHILE IN AUSTRALIA THESE DURICRUSTS SEEM TO BE CONTEMPORANEOUS AND CONTIGREOUS, THEY ARE SUPERIMPOSED IN FRANCE. THE EARLIER ONES HAS BEEN

Duricrusted surfaces provide morphostratigraphic markers which are useful in preliminary extrapolation and correlation at the local and regional scales. Particular reference is made to ferruginous and siliceous cappings. Problems broached include

ferruginized allochems) originated in a coastal area from which they have been removed by storm waves to the open shelf. A working model for their origin is proposed. Discussion of their paleogeographic value (indicators of geotectonic activities

directly related to ferruginous soils and rainfall regime. Bowé soils are characterized by significantly lower values of electrical conductivity, organic matter, extractable phosphorus, silt and total nitrogen than woodland soils, while potassium
exchangeability of bowé soils is higher. Bowé can be expected wherever ferruginous soils and/or ferricretes are observed under unimodal rainfall regimes condition. The disaggregation of bowé ferricretes may improve the soil physicochemical characteristics

U/Th disequilibrium dating of pedogenic ferruginous pisoliths and additional coarse fraction quartz thermolulinescence dates are used to test a TL-based chronology of the Umbakumba Dunefield, Groote Eylandt. These dates support the established
