Evolution of the Kap Edvard Holm Complex : a Mafic Intrusion at a Rifted Continental Margin

The Kap Edvard Holm Layered Series forms part of the East Greenland Tertiary Province, and was emplaced at shallow crustal level (at depths corresponding to a pressure of 1-2 kbar) during continental break-up. It consists of two suites: a gabbro suite comprising olivine and oxide gabbros, leucocratic olivine gabbros and anorthosites, and a suite of wehrlites that formed from the intrusion of th...

Economic and environmental impacts of introducing grain legumes in farming systems of Midi-Pyrenees region (France): A simulation approach

The reconciliation of economy and environment is a key factor in achieving sustainability.The European Union wishes to achieve the sustainability of its agriculture in order to producehigh quality food materials and to manage energy crisis and the risks related to climate andmarket fluctuations. These risks can be mitigated by reducing negative impacts of agriculturalactivities on the environme...

A Mesoarchean Rifted Continental Margin in the Wyoming Province: Evidence for Supercontinent Breakup

The nitrogen isotope biogeochemistry of sinking particles from the margin of the Eastern North Pacific

The nitrogen isotopic composition of time-series sediment trap samples, dissolved NO~ 3 , and surficial sediments was determined in three regions along the margin of the eastern North Pacific: Monterey Bay, San Pedro Basin, and the Gulf of California (Carmen and Guaymas Basins). Complex physical regimes are present in all three areas, and each is influenced seasonally by coastal upwelling. Neve...

Monitoring of the Vallcebre landslide, Eastern Pyrenees, Spain

In 1996 and 1997 a monitoring network was set up at the translational slide of Vallcebre. Fourteen boreholes were equipped with piezometers, wire extensometers and inclinometers. Since then groundwater levels changes and wire displacements have been automatically recorded every 20 minutes. Superficial displacements have been periodically measured with differential GPS. The monitoring network ha...
