  • Pottery manufacture in early Roman Galilee : a micromorphological study
  • The characteristics of, and the sources of the soil materials for, pottery groups manufactured in 3 ancient settlements of early Roman Galilee were studied by micromorphological techniques. The micromorphological comparison of the pottery groups
  • 1999
  • The study of a granitic weathering profile in southern Galicia has shown the presence of smectites, which cannot be explained by poor drainage or by hydrothermal alteration. As the soil is polycyclic, the AA. cannot rule out the possibility
  • that the smectite has been formed under different environmental conditions than the prevailing ones, and the aim of this study was to ascertain the mineral from which it is derived.

  • Microscopic study of twelve weathering profiles developed on granitic rocks in Galicia (NW Spain) showed that, in most cases, the transformation of the parent rock into saprolite occurs with pseudomorphic alteration of the plagioclases

  • This review aims to consider the role of micromorphology as a record of paleoenvironmental change, concentrating in particular on recent developments applying a pedosedimentary approach to loess-paleosol sequences, and illustrated by cases studies
  • 1999
  • The examples, taken in weathered andesitic pyroclasts occurring in the northern and northeastern part of the island of Basse Terre (Guadeloupe), studied here highlight the occurrence of different clay minerals and their spatial variability both

  • This study considers changes occurring on a soil surface after exposure to simulated rainfall. The soil surface has a crop cover of artificial maize, and interest focuses specifically on the surface features produced by leaf drips. An analytical

  • associations requires knowledge of the processes of infiltration and conservation of pollen grains in the soil material. Micromorphology is an important technique to investigate these processes. This is demonstrated in a case study of polycyclic slope deposits
