Titre : Sedimentary structures : their character and physical basis. Vol. 1 Type de document : texte imprimé Auteurs : John Robert Lawrence Allen, Auteur Editeur : Amsterdam : Elsevier Année de publication : 1982 Collection : Developments in sedimentology num. 30A Importance : XVII-593 p. Présentation : ill. Format : 24 cm ISBN/ISSN/EAN : 978-0-444-41935-4 Note générale : Bibliogr. p. 515-593 Langues : Anglais (eng) Mots-clés : Structures sédimentaires Index. décimale : 552.5 Roches sédimentaires Résumé :
This volume begin with a sketch of environmental fluid fynamics and an introduction to sediment transport. Perhaps the simplest of all sedimentary structures as regards setting are those related to the motion of sedimentary practicles through, or their emplacement from, various media. Turbulent boundary layers and their transitional states include small-scale flow configurations to which a number of sedimentary structures seem to be related. It si natural to progress from there to the bedfroms and internal structures related to sand transport by unidirectional currents...And finiches with an account of sandy bedforms beneath currents subject to spatial and or temporal change, where the non-uniformity or unsteadiness in not the fundamental cause of the structures. Such changeable currents are, of cours, the norm in the real xorld, yet they have been insufficiently modelled either theoretically on in the laboratory.Note de contenu : Au sommaire :
1. Environmentals fluid dynamics.
2. Entrainment and trnsport of sedimentary practicles.
3. Practicle motions at low concentration : grading in pyroclastic-fall deposits.
4. Packing of sedimentary practcles
5. Orientation of practicles during sedimentation : sphape-fabrics.
6. Transition to turbulence and the fine structure of steady turbulent boundary layers..

Sedimentary rocks. SedimentationIndex. décimale : 552.5 Roches sédimentaires Résumé :
This volume is about sedimentary structures found in relatively complex physical settings, where groupings or hierarchies of features are often of most interest, and mor emphasis is placed than in the first colume on cohesive as opposed to cohesionless beds.Note de contenu : Au sommaire :
1. Longitudinal bedforms and secondary flows.
2. Free meandering channels and lateral deposits.
3. An outline of folow separation.
4. Sedimentation from jets and separated flows.
5. Flow around a bluff body : obstacle marks.
6. Heat and mass transfer...
7. Flute marks, mud rippled, sichelwannen and potholes.
8. Liquidization, liquidized sediment, and the sedimentation of dense particle dispersions.
