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 (

The Earliest Piece of the Earth A Cool Early Earth New Techniques for Stable Isotope Analysis of Ultra-small Samples UW-Madison Stable Isotope Lab ... UW-Madison Geology Zircons Are Forever John W. Valley William H. Peck Elizabeth M. King The Outcrop for 1999 , University of Wisconsin-Madison Geology Alumni Newsletter, p 34-35. New techniques for oxygen isotope analysis have lead to the first studies of oxygen isotope geochemistry of zircons (1,2). Zircon is shown to be highly retentive of oxygen isotope ratios, preserving the best record of igneous composition even in samples that have enjoyed high grade metamorphism or hydrothermal alteration. Figure 1 Figure 2 Zircon is a ubiquitous trace mineral (ZrSiO ) in many igneous, metamorphic, and clastic sedimentary rocks. Its ability to concentrate uranium and exclude lead forms the basis of U-Pb geochronology and its refractory nature and concentric growth patterns create robust records of crystallization age. The ability to analyze oxygen isotope ratios in a sample that has been dated, directly links the magmatic composition to known geologic events and has opened many new and exciting avenues for study. Several recent graduate theses at the University of Wisconsin-Madison have incorporated some aspect of zirconology: Carrie Gilliam (MS 1996) and Salma Monani (MS 1999) showed that shallowly intruded, sub-volcanic Tertiary granites from the Isles of Skye and Arran, Scotland formed by

The course will cover both equilibrium and kinetic descriptions of the processes which affect the fate of pollutants. W will link the effects of these processes on pollutant bioavailability remediation and ecotoxicology Edwards aquifer recharge zone , Austin Texas. Photo B. Herbert. We will conceptualize the Earth as a system, focusing on specific suficial systems such as soils, sediments, groundwater, lakes, wetlands and estuaries. In particular, we will explore the use of a reductionist approach to the understanding of these complex systems.
