“…Glasmann & Simonson (1985) and Prudêncio et al (2002) studied influence of rainfall, average annual air temperature and topography. As the intensity of the weathering processes is enhanced by hot wet conditions, numerous studies have been carried out in tropical climates (e.g., Cortes & Franzmeier 1972, Motuzova & Ngo Thi Hong Van 1999.…”

We have examined the behavior of Cr, Ni, Cu and Zn during the weathering of basaltic rocks in a moderate temperate climate. Samples of unweathered basaltic rocks, moderately weathered and strongly weathered equivalents were studied at six sites from the Massif Central of France. Unweathered basaltic rocks and basanites are rich in Cr (248-455 mg/kg) and Ni (126-237 mg/kg); all four elements are present in similar amounts in all three categories of sample. The location of these trace elements was investigated by optical and electron microscopy (EMPA, SEM-EDS). In unweathered basaltic rocks, Cr bearing phases are: chromian spinel (4-42 wt%), Fe-Ti spinel (0.12-1.24 wt%) and titanian augite (200-8000 mg/kg), whereas nickel is incorporated into forsterite (830-3600 mg/kg) and the spinel-group minerals (0.11-0.14 wt%). Copper and Zn are found at lower concentrations, but regularly distributed in the phases studied. In weathered samples, authigenic phases fill fractures and also replace the primary minerals. They are composed of mixtures of clays, iron oxides and organic compounds. Authigenic phases contain lower amounts of those trace elements than primary minerals. Under conditions of moderate weathering, only 20 to 40% of the total content in Cr, Ni, Cu and Zn appears to be mobile during the weathering of the basaltic rocks. As spinel-group minerals are not affected by strong weathering under a temperate climate, only the fraction of Cr, Ni and Zn present in the silicates of the unweathered basaltic rocks is released. SOMMaireLe comportement des éléments traces Cr, Ni, Cu et Zn lors de l'altération de roches basaltiques en climat tempéré a été examiné à six sites situés dans le Massif Central français. Cette étude a permis d'établir un schéma général du profil d'altération dans lequel trois faciès ont été définis: les échantillons non altérés, modérément altérés et très altérés. Les roches basaltiques sont riches en Cr (248-455 mg/kg) et en Ni (126-237 mg/kg), avec des concentrations totales des quatre éléments comparables dans les trois faciès d'altération. Les phases primaires et authigéniques porteuses de ces éléments ont été identifiées et caractérisées par microscopie optique et électronique. Dans les roches basaltiques non altérées, les phases porteuses du Cr sont: le spinelle chromifère (4-42%, poids), la magnétite titanifère (0.12-1.24%) et l'augite titanifère (200-8000 mg/kg), tandis que le Ni est incorporé dans la forstérite (830-3600 mg/kg) et les deux sortes de spinelle (0.11-0.14%). L'ensemble des phases étudiées contiennent de faibles teneurs en cuivre et en zinc. Dans les échantillons altérés, les phases authigéniques remplissent les fissures et remplacent les minéraux primaires. Ces phases authigéniques sont constituées d'un assemblage d'argiles, d'oxyhydroxydes de fer et de composés organiques avec des teneurs en Cr, Ni, Cu et Zn inférieures à celles des minéraux primaires. Dans les conditions actuelles du Massif Central français, seul 20 à 40% de ces éléments sont redistribués durant l'altération s...

“…Powder XRD was the only analytical technique that evidenced the presence of this silica polymorph (Jones & Segnit, 1971). Cristobalite has been reported to naturally occur in various size fractions (predominantly clay) of several soils derived from volcanic ash in South America and Costa Rica (Besoain, 1969; Calhoun et al., 1972; Cortes & Franzmeier, 1972; Mejia et al., 1968; Wright, 1964). It is probably a component of the parent erupted magma from which these soils developed.…”

Volcanic ash-derived soils are naturally deficient in the essential micronutrient B, but they also have maximum adsorption capacities (b B ) that are as much as 40 times greater than in nonvolcanic soils, further exacerbating B availability. Because short-range-order (SRO) aluminosilicates (allophane and imogolite) and iron (Fe) oxyhydroxides are the main clay-sized minerals in these soils, we hypothesized that their relative abundances would explain variations in boron sorption capacity (b B ). We characterized 23 volcanic ash-derived soils (Andisols and non-Andisols) from the Pacific coastal plain of Guatemala by X-ray diffraction, oxalate and pyrophosphate extractions, and thermal analysis, with four selected soils further examined by Mössbauer spectroscopy (MBS). Only soils with andic character (high SRO Si-Al content) contained considerable amounts of imogolite, with allophane in the clay fraction. Overall, soil SRO Al-Si phases were strongly correlated with clay B adsorption capacity (R = 0.65, p < 0.001) and clay specific surface area (R = 0.88, p < 0.001) suggesting that SRO Al-Si phases are the dominate influence on B behavior in these soils. Fe mineral composition was dominated (39%-71% of total Fe) by SRO Fe(III) oxyhydroxides (nanogoethite and ferrihydrite) of various crystallinities. In low allophane soils, SRO Fe phase abundance correlated with b B as did the abundance of low crystallinity kaolinite phases, suggesting these phases are important when SRO Si-Al content is low. Any efforts to predict B behavior or plan soil fertility treatments in volcanic-influenced soils needs to consider the impact of SRO phases.

“…Such soils are andosols or, less likely, latosols or lateritic soils. This is illustrated by extensive literature on soils from the Hawaiian Islands and volcanic regions bordering the Pacific Basin or on soils derived from ash deposits and basalts by tropical or sub-tropical weathering (Sherman et al, 1948;Sherman, 1950;Segalen, 1957;Patterson and Roberson, 1961;Correns, 1962;Loughnan, 1969;Colmet-Daage et al, 1970;Leonvallejo and Segalen, 1970;Cortes and Franzmeier, 1972;Mohr et al, 1972;Gibert, 1973;Dixon and Weed, 1977). The red claystone facies differs also from oceanic volcanosedimentary sequences in surface sediments, such as those described by Hoffert et al (1978).…”
