Borehole images now form a major part of the interpretation strategy for subsurface geological interpretation in a wide variety of scenarios. This volume attempts to document some case histories together with image acquisition and analysis techniques. It by no means covers the full breadth of the subject but is intended to provide a valuable source of information within one volume. We hope the broad spectrum of this text will encourage geologists to look outside their immediate areas of interest with the potential to learn from complementary work in other areas. <...>

The International Young Scholars’ Symposium on Rock Mechanics 2008 has been organized by the ISRM Commission on Education and supported by the University of Science and Technology Beijing (USTB), China University of Mining and Technology (CUMT) and Chongqing University (CU), under the sponsorship of the International Society for Rock Mechanics (ISRM) and the Chinese Society of Rock Mechanics and Engineering (CSRME).

Lorsque l'on se propose d'étudier les Brachiopodes du Lias et du Dogger , on est surpris par le grand nombre d'espèces créées aussi bien que par le nombre d'ouvrages décrivant des Brachiopodes . Devant un sujet aussi vaste , devant des efforts aussi dispersés , il m'a paru opportun de faire le point : dénombrer les espèces nouvelles d'après les recherches bibliographiques , mettre sur fiches méca-nalytiques leurs diagnoses originales , établir les listes synonymiques critiques est le premier travail à effectuer et il a pour résultat l'obtention de la durée moyenne  de  vie  pour chaque  espèce   (répartition stratigraphique) <...>

Progress towards a fuller understanding of the dynamics and deposits of braided rivers demands an interdisciplinary approach to a host of unresolved problems. Although many advances have been made within recent years in interpreting the mechanics of flow, transport of sediment and sedimentary architecture of braided rivers many key issues remain to be addressed. In particular, several areas demand attention: the mechanisms of braid bar initiation; confluence-diffluence dynamics, the nature of sedimentary facies over a range of grain sizes and the influence of flow stage and aggradational regime upon the depositional architecture over a range of channel scales. This paper focuses upon these issues and highlights several areas of fruitful future interdisciplinary collaboration.
