STUDY OF THE RECENT STRUCTURAL EVOLUTION OF CONTINENTAL BASINS IN ALTAI-SAYAN (CENTRAL ASIA) goto Boris Dehandschutter's home page OUTLINE The active deformation in most of Northeast Altai ( chapter 1 ) is far from understood, mainly because of the poor tools geologists have in assessing active structures and determining active faults in basement terranes. Except from the historical earthquake related fault movements and deformation in large Cenozoic basins such as Chuya and Zaisan, the timing of Cenozoic faulting and related deformation remains unknown. The Cenozoic kinematics of the major faults in the region has only been estimated from single-image remote-sensing and large-scale modelling on lithospheric scale, and detailed remote-sensing and field-based data are lacking. The behaviour of the tectonic stress field in highly heterogenous basement terranes and its relation to the active and upper crustal movements are poorly understood. And finally, the perception of the tectonic and geodynamic meaning of the specific wrench-zone related deformation in the area, combining range uplift with extensional basin formation is poor. The study area a is typical locality of complex active deformation that is difficult to assess by classical geological and/or geophysical tools (based on stratigraphy), due to the lack of a developed stratigraphic sequence for the Cenozoic. We focus on the determination of active and recent deformation and tectonism, using remote sensing, structural field observations and geophysical information. The use of these methods is discussed in the following three chapters (

W e lcome to the The International Association of Geochemistry and Cosmochemistry (IAGC). The IAGC was established on May 8, 1967 as a nonprofit scientific society affiliated with the Internati onal Union of Geological Sciences. It has been one of the pre-eminent international geochemical and cosmochemical organizations for over twenty-five years. The principal objective of the association is to foster cooperation in, and advancement of, geochemistry and cosmochemistry in their broadest sense: by working with any interested group in planning symposia and other type of meetings related to geochemistry; by sponsoring publications in the geochemistry of a type not normally covered by existing organizations; and by appointment of Working Groups to study problems that require, or would profit from, international cooperation.

53. Acid Mine Drainage University of Waterloo research into groundwater geochemistry and remediation of acid mine wastes. http://www.science.uwaterloo.ca/research/ggr/MineWasteGeochemistry/AcidMineDrain

Remediation Department of Earth Sciences University of Waterloo Acid Mine Drainage Introduction The oxidation of sulfide minerals and consequent release of acid in tailings impoundments can last for decades to centuries. The interaction of the low-pH, metals and sulfate contaminated water with tailings and aquifer minerals initiates a sequence of pH-buffering reactions. This increase in pH is often accompanied by the precipitation of metal-bearing hydroxide and hydroxysulfate minerals that remove dissolved metals from the moving water. Research in our group has focused on the mechanisms and consequences of aqueous geochemical and mineralogical changes that occur within and below sulfide tailings impoundments. The research typically involves field and laboratory investigation, enhanced by groundwater flow, geochemical, transport and reactive transport modelling. The research has been collaborative with major companies in the Canadian mining industry, including Agnico Eagle, Falconbridge, INCO, Noranda and Placer Dome. Research assistance has also been provided from NSERC (Natural Sciences and Engineering Research Council of Canada)

Started 25 years ago by Scientist Emeritus Werner Deuser, the OFP uses moored sediment traps near Bermuda to continuously measure the carbon flux to the deep ocean. It is the longest record of its kind. The research programs of Assistant Scientists Katrina Edwards and Chris Reddy are part of a new departmental initiative in microbial biogeochemistry. Katrina is studying the role of microtopography in microbial attachment to mineral surfaces. This research has important implications for life in the deep ocean, how rapidly minerals weather, and biofouling in the marine environment. Chris is conducting research crucial to understand the long- and short-term effects of oil spills in the ocean. He is using comprehensive two-dimensional gas chromatography to study the effects of microbial degradation on sedimentary petroleum hydrocarbons in both laboratory and field samples (see Project Highlights story on the

In particular, I am interested in environmentally significant processes such as crystal growth, metal sorption, trace element partitioning and other surface mediated reactions. My research also addresses the structural response of minerals to substituent elements, especially lanthanides and actinides in apatite group minerals. Current research projects include: The role of crystal surface structure on trace element incorporation during growth; geochemical implications and dating of compositional zoning in minerals; crystal chemistry of the lanthanides and actinides in apatite; crystal growth and trace element incorporation in fluorite and apatite; understanding fundamental interactions between aqueous metal species and soil minerals; structural transformations in clay minerals.
