Contribution Ă la connaissance de la chronologie des terrasses lacustres de Banyoles (Gerona)
Bref exposé de la situation et des caractéristiques des terrasses travertiniques de Banyoles (Gerona, Espagne). Nous basant sur des trouvailles paléontologiques personnelles et des considérations paléoclimatiques et paléopédogénétiques nous avons voulu contribuer à la connaissance de la chronologie de ses travertins : Mindel pour les travertins de la terrasse « haute » de Usall-Espoia, Riss-Wurm pour ceux de la terrasse « basse » de Banyoles-Mata et pour ceux de la terrasse « moyenne » possible de Liô
Sinopsi dels sòls dels Països Catalans
In this publication are combined the pedological studies and observations wich, since 1962, the author has made in the Catalan Countries (including French Catalonia, the Balearic Islands and Valencia). Basically, he has used the French system (C.P.C.S., 1967), indicating the correlations
with those of Kubiena (1953), the 7th Aproximation U.S.D.A. ( 1973) and classification of the
F.A.O. (1971).
After setting out principal pedological characteristics of the Catalonia soils, which show a great typological variety because of the climatic, lithological and orographical mosaic of this region of the western mediterranean, they are described following a criterion of altitudinal zonality.
The soils of high mountain areas, medium height areas and of the plains are ennumerated, being fully representative of the «azonals» and «intrazonals» types
ContribuciĂł al coneixement dels sòls fersialĂtics del sud de LiĂł (França)
The macromorphological and physicochemical characteristics of fersialitic soils from the Corbas plain and from the Saint Symphorien d'Ozon, Villete de Vienne and Pont Eveque
depressions (Lyon-Vienne area), are explained, indicating their relict nature.
Profiles, one from the «fersialitic with calcic reserve. group located on a fluvioglacial terrace probably dating from the fini-Wurmian period, and two from the «fersialitic» without calcic reserve,, group on moraines which show signs of cryoturbation, and of an older
pedogenesis, Riss-Wurm or perhaps Mindel-Riss, are presented.
The first one shows a pH of between 7 and 7,2, a saturation level greater than 65 % and a clay illuviation index of more than 1/1,4. But from the iron illuviation index and the lower level of saturation -V- in the horizon B3 (50,3), it would perhaps be necessary
to consider this soil as being a stage between the fersialitics with calcic reserve and those without it. From its colour it should perhaps be placed between the brown and the red fersialitics.
The second profile corresponds to a reddish brown acid fersialitic soil (pH less than 5), only slighthly illuviated and devoid of calcic reserve. Judging by the pH it belongs to the IX/22 group (CPCS, 1967) but from the clay illuviation index which is greater than 1/1,4 it resembles the IX/21 group. Thus, it seems like a IX/22-IX/21 slightly illuviated fersialitic intergrade.
The third profile described, a red acid fersialitic soil without calcic reserve, would also be taxonomically better classified as being between IX/21 and IX/22, due partly to
the pH value and the dose of iron liberation in the horizon B, and partly to the exceedingly high values of the saturation complex as well as the clay illuviation index which is greater than 1/1,4
