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. <...>

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.

Some photos speak for themselves. Some gestures communicate more than words ever could, like these clasped hands, which seek comfort in the face of fear of the unknown. The picture was taken Oct. 8, 2005, when aftershocks were still being felt from the strongest earthquake ever to strike Kashmir, in northern India.
Those clasped hands symbolize terror and panic; they speak of fragility and helplessness, of endurance in the face of chaos. Unlike storms and volcanic eruptions, earthquakes are unpredictable, unleashed within seconds, and without warning. They spread destruction and death, forcing millions to flee from their homes. The day after the catastrophe revealed a terrifying scene: debris everywhere, a number of people injured and dead, others wandering desperately, children crying, and over three million survivors seeking help after losing everything. Throughout history Earth has been shaken by earthquakes of greater or lesser violence. These earthquakes have caused great harm. One of the most famous is the earthquake that rocked San Francisco in 1906. Registering 8.3 on the Richter scale, the temblor left nearly three thousand dead and was felt as far away as Oregon to the north, and Los Angeles in southern California. <...>
