    The influence of time as a soil forming factor was studied on an evolutionary sequence of five soils (1850 radiocarbo years BP-ca. 120,000 BP) developed in rhyolitic tephra deposits in New Zealand. New micromorphological observations were combined with existing macromorphological, chemical, textural, and clay mineralogical analyses to assess the extent of polygenesis in the soils. The younger soils (1850 BP to ca. 22,600 BP) are characterised by initial weathering and little secondary mineral formation. This status is expressed by abundant pumice fragments and fresh, easily weatherable minerals, as well as a low clay content with an isotropic character. Comminution and neoformation are the main pedological processes. The older soils (ca. 120,000 BP) are characterised by a high degree of alteration of primary minerals, little or no pumice fragments, clay illuviation, gleying, and a high clay content (>80%) consisting of a range of crystalline clay minerals including halloysite, gibbsite, kaolinite, and vermiculite, plus crystalline iron oxides. Evidence of polygenesis can be observed in the micromorphology of the older soils: (1) the range of secondary minerals is the result of the integration and succession of soil-forming processes through time; (2) the accumulatory character of the tephra deposits has resulted in stronger weathering of the lower horizons than upper horizons because of continuous pedogenesis. Such polygenesis in the older soils supports the view that the older the soil, the more polygenetic it is likely to be. Copyright

    Mineral transformation at the earth surface is a complex process. In volcanic ejecta, such transformations tend to be fairly rapid. Many weathering studies on volcanic materials have been carried out at different scales of observations, mostly using bulk samples. However, to get a proper understanding of the mechanisms of weathering of primary minerals and formation secondary minerals it is necessary to obtain data of undisturbed material at the scale of observation that micromorphology and submicroscopy deal with. Weathering studies at the micrometre scale with help of micromorphology showed the heterogenous character of mineral weathering and the co- existence of different secondary minerals.

    The main objective of papers in this thesis was to characterize and explain alteration of primary minerals and formation of secondary minerals at the particle level in volcanic soils in relation to (micro) environmental conditions.
    Thin sections of volcanic soils were studied by micromorphology, and relevant features were characterized chemically and mineralogically by submicroscopical methods performed on (un)disturbed samples isolated from thin sections.
    Mineral transformations were studied both on sites in the temperate humid zone and in the humid tropics.

    In a chronosequence of Quaternary terraces of the Allier in France, micromorphological and sub microscopical analyses showed:
    - Alteration of basaltic particles leads to clay formation whereas weathering of granite fragments contributes to the sand fractions.
    - A relative increase in the contents of Ti, Al, and Fe and a decrease of K, Na, Ca, and Si occur in weathering rinds of basalt pebbles. Differences in weathering intensity are predominantly a function of chemical composition of the basalt rather than a function of time.
    - A mass balance calculation carried out on an isovolumetric, altered basalt pebble with a fresh core, and on an enclosed, genetically related neoformed clay coating showed that all elements, except Fe were leached from all weathering rinds. Only Si, Al and some Ca were found in the clay coating, and part of the Al was derived from an external source.
    - Isotropic and anisotropic coatings occur in a Paleosol in an older terrace. Micromorphological observations demonstrated that such coatings are genetically related. The isotropic coating consists of allophanic material with minor amounts of 2:1 phyllosilicates, whereas the anisotropic types consist of 2:1 phyllosilicates only. Both types result from recombination of trachytic weathering products under restricted leaching conditions during coating formation.
    - Micromorphological observation demonstrated three types of coatings in two Planosols in two older terraces. Isotropic and anisotropic, translucent materials occur locally within one coating, suggesting a genetic similarity. These coatings are due to secondary mineral formation, The third type, anisotropic dusty clay coatings clearly resulted from clay illuviation. Cluster analyses reveal that the coatings of the same type were chemically more alike than different coatings in the same profile. About 83% of the grouped samples were classified correctly as either isotropic and anisotropic weathering coatings or anisotropic illuviation coatings.

    A technique is described to isolate undisturbed microparts of pedofeatures from thin sections. Such microparts can subsequently be analysed by Transmission Electron Microscopy. This technique allows performance of micromorphological, mineralogical and chemical analyses on one undisturbed micro sample at micrometre to nanometre scales.

    Isotropic coatings in the C horizon of a young Hapludand in Guadeloupe and in the C and R horizons of an old Hapludand in Costa Rica, both developed on andesitic volcanic materials were allophanic. Isotropic coatings present in the Bw horizons of both soils contain allophane and imogolite. The Al/Si molar ratios in the coatings in the Bw horizons are higher than those in the coatings of the C and R horizons. Anisotropic coatings are wholly gibbsitic and occur only in the Bw horizon of the older Costa Rican Hapludand. The gibbsitic coatings show a gradual transition to isotropic coatings and both types looks alike in plane polarized light suggesting a genetic relationship. The allophane coatings resulted from initial weathering of the parent materials, whereas the gibbsite coatings represent the ultimate stage of secondary mineral formation. The differences in chemical and mineralogical composition of the coatings are thought to be the result of different leaching conditions at the macro and micro scale.

    2:1 Phyllosilicates in Hapludands on Holocene andesitic beach ridges in Costa Rica occur as clay pseudomorphs after primary minerals. They are inherited from hydrothermally altered parent material from which the beach ridges were derived, and are not due to post depositional soil formation. Weathering and biological activity affect the clay pseudomorphs which leads to clay- sized particles consisting of 2:1 phyllosilicates. They are incorporated in the allophanic groundmass that results from actual soil formation in the Hapludands.

    Isotropic coatings also found in a West Java (Indonesia) Oxisol on andesitic volcanic parent materials are probably due to weathering of airborne ash additions. The coatings recrystallize to anisotropic coatings suggesting a neoformed genesis. Both types of coatings appear to be common in three andesitic catenas in Indonesia. The amount of coatings and the crystallinity tend to increase as the dry season become more pronounced. The anisotropic coatings can easily be confused with illuviation coatings.

    In the past, investigations on surface seals developing under simulated rains usually were performed with uniform rainfall intensities. Recent studies, however, showed that varying-intensity rains affect erosion and volumes of runoff. We conducted a study on surface sealing under varying-intensity rains using physical and morphological methods. Four 1-h-duration rainfall patterns were used: S1, S2, S3 and S4, with mean rainfall intensities of 83, 69, 65, and 51 mm h-1, respectively, and highest intensities of 148, 120, 111, and 100 mm h-1, respectively. Two experiments were performed in triplicate: (i) in packed soil columns, pressure heads at 1-cm depth were measured, and runoff (Rt) and wash sediment (St) collected at short time intervals during S1, S3, and S4 patterns; and (ii) packed shallow soil flumes were successively exposed to 10, 15, 30, 40, and 60 min of S2 and S4 patterns, and the surface was then characterized by micromorphological analysis of thin sections (S2) and top-view photographs (S2 and S4). The largest differences between rainfall patterns occurred during the intensity peaks (10–30 min): at the end of these periods, measured surface seal hydraulic conductances (β) attained values of 0.80, 0.25, and 0.51 h-1 for S1, S3, and S4, respectively. These relative β values are thought to be due to partially open surfaces as a result of microrill erosion (S1), complete sealing without erosion (S3), and incomplete sealing (S4). Presented Rt, St, and morphological data support these conclusions. After 5 min of the intensity peaks of S2, surface seals attained maximum observed thickness and minimum macroporosity (>30 µm). Planar voids (>500 µm) were eliminated at this point. Under continuing rain, erosion reduced the seal thickness and increased macroporosity, mainly as planar voids
