  • An extensive zone of mylonites, up to 10km thick, on the coastal margin of the West African Craton is a suture developed during the late Archaean at the site of collision of two granitic continental masses, now preserved in a partially reworked
  • La phytocoenologie comme outil de définition des secteurs côtiers à préserver in Les côtes atlantiques de l'Europe. Evolution, aménagement, protection.
  • La méthode phytocoenologique, qui consiste à définir les unités élémentaires de végétation, paraît être la meilleure pour le choix des secteurs côtiers à protéger. Fondée sur une liste d'associations en un site donné, elle fournit une expression de
  • . The marine to estuarine origin of this terrace is indicated by the presence within it of a biocoenosic, sea-marginal to estuarine, assemblage of well-preserved molluscs consisting of taxa tolerating brackish-water, together with a few fresh-water specimens
  • . The transgressive marine sediments onlap and overlie a 2700-yr-old middle Iron Age (Phoenician) tomb, which was built on a dark clay layer, containing a middle Bronze IIB (3750 yr B.P.) settlement. In post-Roman times the coastal zone at this site, both east
  • Preservation of the rescaled adjusted range. 3. Fractional Gaussian noise algorithms
  • landforms in the area. One possible explanation for the preservation of the ridges is that they were created before the last phase of deglaciation and were preserved under cold-based ice.
  • Preservation of correlation in generated hydrologic samples through two-station models
  • The preservation of skewness in linear disaggregation schemes
  • An operational approach to preserving skew in hydrologic models of long-term persistence
  • Preservation of the rescaled adjusted range. 2. Simulation Studies using Box-Jenkins models
  • Preservation of the rescaled adjusted range. 1. A reassessment of the Hurst phenomenon
  • Low aspartic acid D: L ratios and modern collagenlike concentration values indicate that amino acids in bones from the Rancho La Brea asphalt deposit, Los Angeles, California are better preserved than amino acids in bones of equivalent age that have
  • not been preserved in asphalt. Amino acids were recovered from 10 Rancho La Brea bone samples which range in age from less thant 200 to greater than 36,000 yr. The calibrated rates of aspartic acid racemization range from 2.1 to 5.0 10yr. Although this wide
  • Applied mountain geoecology. Can the Scientist assist in the preservation of the mountains? in The Himalaya. Aspects of change.
  • La composition chimique de l'atmosphère et le rôle des études de climatologie pour préserver son équilibre. - (CAM)
  • apparently decreased through time owing to regional tectonic uplift. This had led to the preservation of a more complete sequence of glacial deposits than in the Sierra Nevada.
  • Les effets de la couverture glaciaire sur les formes et les aquifères karstiques peuvent supprimer, inhiber, préserver ou stimuler l'évolution karstique. Huit types de développement sont reconnus selon différents exemples canadiens de couverture
  • Nouvelle technique d'échantillonnage des sédiments meubles lacustres basée sur le principe de congélation rapide de la carotte in situ afin de préserver sa microstratigraphie et de faciliter l'analyse à intervalles rapprochés.
  • . In the lower ranges of this facies, the intact megaripple forms have been preserved under a cover of vaguely horizontally laminated sands. The latter could be the result of rapid storm deposition on the lower flank of the sand ridge. - (Les AA.).
  • This study examines the dichotomy that C 14 ages for noncollagenous fossils are underestimated, whereas ages for collagenous fossil bones are more accurate. There is a high probability that amino acids from poorly preserved fossils will date younger
  • with the importance of halloysite in the clay fraction, indicates that the weathering predates the middle Quaternary ice sheet glaciations. The weathering demonstrates very limited erosion of the preglacial slopes and owes its preservation in part to the development
  • are often well preserved and the metasedimentary rocks are usually hard hornfelses. Other morphological breaks are caused by resistant mylonites along nappe boundaries, one prominent example occuring beneath Storglaciären.
