The overarching objective of our research is to further our understanding of the interactions between biosphere and environment, both at present and in the past. The problems studied require an interdisciplinary approach. This is reflected in the composition of the research group, consisting of closely collaborating biologists, chemists, and geologists. Studied Materials Organic molecules extracted from: - sediments and rocks as archives of information on paleoenvironmental conditions biogeochemical processes - extreme environments such as deeply buried sediments, methane seeps and hydrothermal vents as indicators for

These pages are currently in their juvenile stage, so please do not hesitate to mail alternative methods, errors, references or useful links. The main objective of the current marine investigations are both porewater and solid phase analysis of sediment material recovered during several cruises with the research vessel METEOR . Published data from these cruises may be accessed through the PANGAEA database system. In our group, modelling of porewater and sediment interactions and diffusive processes is performed using CoTReM a computer software created for the simulation of one-dimensional transport of solutes and solid phases and their interactions driven by bio-geochemical reactions and thermodynamic equilibria occurring in natural environments.

This research includes detailed field investigations, laboratory studies, development of reactive barriers and other passive remedial solutions, and development of mathematical models to predict the complex geochemical behavior of these systems. We have conducted detailed investigations of mine sites, mine-waste disposal facilities, wetlands, on-site sewage disposal systems and other industrial sites. Laboratory studies often focus on reaction mechanisms utilizing batch and column experiments. Mathematical modelling has focused on the development of fully-coupled reactive transport codes that can account for thermodynamic and kinetic controls on chemical reactions between groundwater and the aquifer material. Remediation research is focused on the development of passive, in situ , methods including permeable reactive barriers.

74. GEOCHEMISTRY The variation in major element geochemistry can be related to the alteration observed within the gabbros of Site 1268. The two uppermost samples of Unit IV http://odp.pangaea.de/publications/209_IR/chap_03/c3_5.htm

GEOCHEMISTRY O, CO , and sulfur. These 27 samples are representative of the highly altered material recovered from Hole 1268A (see "Igneous and Mantle Petrology" and "Metamorphic Petrology" ). The results for the major and trace elements are reported on a volatile-free basis for both ultramafic and mafic rocks (Table ). In order to determine the optimum analysis conditions for elements at low concentration in ultramafic rocks (Ti, Al, K, Na, Sr, V, Cu, Co, Ni, Cr, Sc, Y, and Zr), the first six samples were analyzed at three different dilutions (4000-, 2000-, and 1000-fold). Although detection limits and precision for elements present in low abundance should have been improved at lower dilution factors, instrument performance and stability degraded significantly. This compromised our ability to efficiently perform high-quality shipboard measurements at the higher analyte concentrations present in the 1000-fold and 2000-fold dilutions. Maximum analytical efficiency was achieved by using shorter elemental menus for each run, operating at 4000-fold dilution, and running major and trace elements as separate analytical routines. Peridotites Bulk-rock analyses of peridotites from Site 1268 show that their compositions were significantly modified by hydrothermal alteration, leading to the addition of variable amounts of volatile constituents. The ultramafic rocks with predominant serpentine alteration, based on the visual core descriptions and XRD results (see
