Kimman, Wouter P. (author)Dynamic stress generated by an eartliquake is one of the major causes for triggering of landshdes. The role of the dynamic stresses is not completely understood. It has been speculated that tensile stress associated with lateral ground acceleration can play an important role in generating landshdes, but the mechanism is not well understood. Both...report 2005

van Geffen, P.W.G. (author)Geochemical field research in Botswana was performed during six weeks in July and August 2004, as the basis for this doctoral study / MSc thesis, at the Geochemistry Division, Department of Earth Sciences, Utrecht University. The Tati Nickel Mining Company (TNMC) offered the opportunity to study their Ni-Cu-PGE deposits Phoenix and Selkirk,...report 2005

Kootstra, Dirk-Sytze (author)The purpose of this report is to give an overview on methods using surrogate variables to obtain glacier mass balance and to test one of the methods on Storglaciaren, a small valley glacier in northern Sweden. Surrogate variables used for detecting mass balance are meteorological variables like temperature and precipitation, variables related to...report 2005

Straathof, G. (author)A paleomagnetic study has been carried out to discriminate between two end-member scenarios on the intra-continental, transpressional strike-slip system in the Gobi-Altai, southern Mongolia. The first suggests that these strike-slip faults utilise obliquely oriented weak Paleozoic or Mesozoic zones in the basement. The second scenario suggests...report 2005

Wijnker, E.T.G. (author)In recent years a sand pit in Mill, Noord-Brabant, has developed into a productive fossil site in The Netherlands. Large amounts of fossils are found that stem from marine deposits. The site in Mill is relatively new and little has been published on the site yet. The found fossils comprise many bones of birds. This paper deals with these avian...report 2005

Eeman, Sara (author)Soil conservation is an important issue in large parts of the world. Controlling or preventing erosion is one of the most important ways to achieve this. In designing erosion prevention measures for a specific area, modelling can be very useful. One such model is LISEM, which has been used in a number of projects worldwide. An area in which...report 2004

Vrijlandt, Mark (author)The location of seismic events can be determined from waveforms recorded at different stations using a velocity model. Errors in this velocity model introduce an error in the computed locations of the events. Determining the relative location between two events is less dependent on errors in the velocity model than determining the absolute...report 2004

Wever, Andries (author), Spetzler, Jesper (author)The effects of mis-positioning in time-lapse seismics aie studied, focusing on irregular sampling due to receiver mis-positioning and absence of data due to surface obstacles. Wavefield reconstruction is used to regularize data and to reconstruct data where data-gaps are present. The method is tested on time-lapse 2D synthetic and Troll streamer...report 2004

van Benthem, S.A.C. (author)We calculated the anisotropy parameters, 8t and (p, under stations of the Servicio Sismologico Nacional (SSN) - and the Network of Autonomously Recording Seismographs (NARS) - networks. In order to calculate the shear wave splitting of mainly SKS-phases we used two different methods: One that does a grid search in order to find that combination...report 2004

Meijers, M.J.M. (author), Deenen, M.H.L. (author)Paleomagnetic data for determination of paleolatitude were collected in the North Dobrogea Orogen (Romania) and on Crimea (Uki-aine), to discriminate between scenarios on the Mesozoic geodynamic evolution of those areas, which are situated at the southern margin of the East European Platform. To correct for the inclination error in sedimentary...report 2004

Mazumder, Saikat (author), Plug, Willem-Jan (author), Bruining, Hans (author)Enhanced Coal Bed Methane (ECBM) recovery techniques, based on carbon dioxide injection, have been proposed for the recovery of larger fraction of methane in place. Laboratory studies and recent pilot field tests demonstrate that CO2 injection has the potential to enhance coal bed methane recovery through displacement desorption mechanism with...report 2003

Engels, S. (author)In the summer of 2001 a research project studying modem and historical aeolian deposition rates was carried out in the Kangerlussuaq-region, West Greenland. Modern deposition rates were monitored using 20 modified Tauber traps. The traps were placed on two perpendicular transects to assess the spatial variability in deposition rates. They were...report 2003
