Subduction is a major process that plays a first-order role in the dynamics of the Earth. The sinking of cold lithosphere into the mantle is thought by many authors to be the most important source of energy for plates driving forces. It also deeply modifies the thermal and chemical structure of the mantle, producing arc volcanism and is responsible for the release of most of the seismic energy on Earth. There has been considerable achievements done during the past decades regarding the complex interactions between the various processes acting in subduction zones. This volume contains a...

Comet nuclei are the most primitive bodies in the solar system. They have been created far away from the early Sun and it is supposed that their material has been altered the least since their formation. The workshop was bringing together representatives of several scientific communities in the fields of interstellar clouds, star-forming regions, the solar nebula, and comets. The intent was to formulate the current understanding and interconnectivity of the various source regions of comet nuclei and their associated compositions and orbital characteristics.

The goal was to better...

Any sustainable groundwater development programme requires knowledge of the prevailing flow system, extending from local to regional scale. This book of selected papers discusses integral groundwater management with scale flow issues and presents methods of defining, preventing, controlling and mitigating negative environmental impacts related to groundwater. It highlights specific issues such as trans-boundary groundwater flow, groundwater recharge, groundwater mining, and groundwater flow in thick aquifers, and stresses the importance of the sustainable development of groundwater and its...

Since 1998, the Dutch Ministry of Agriculture, Nature Management and Food Quality (LNV) promotes development-orientated agricultural and environmental research and strengthening of North-South partnerships through its International Cooperation (DLO-IC) research programme. By 2005, some 70 collaborative North-South projects had been carried out. All science groups in Wageningen University and Research Centre (WUR) were involved in the implementation of the programme and at least half the projects and activities undertaken were directly related to Rural Development and Sustainable...

• Chronicles how successive generations of natural philosophers, geologists and geomorphologists have come to invent different views of the Earth over the last 250 years.
  
• Uses as its central viewpoint changing ideas about the significance of the action of rain and rivers on the Earth's surface.
  
• Shows how our contemporary -truths- have come to be accepted and exposes...

The Mjolnir impact structure was recognized in 1993 and included in the Earth Impact Database in 1996, based on the discoveries of unequivocal meteorite impact indicators such as shocked quartz, Ir-enrichments, possible glass remnants, fragments of nickel-rich iron oxides, in addition to the convincing complex crater shape of the structure. This book presents the geological and geophysical history of the Barents Sea region along with the discovery of the Mjolnir impact crater. We place the Mjolnir event into the geological framework of the region and present elaborative numerical models of...

High levels of uncertainty are a trademark of geological investigations, such as the search for oil, diamonds, and uranium. So business ventures related to geology, such as mineral exploration and mining, are naturally associated with higher risks than more traditional entrepreneurial ventures in industry and economy. There are also a number of dangerous natural hazards, e.g. earthquakes, volcanic activities, and inundations, that are the direct result of geological processes. It is of paramount interest to study them all, to describe them, to understand their origin and - if possible - to...
