Thrust-related fluid flow coupled with isotopic exchange between fluid and rock is simulated in a three-dimensional finite-element model of the Glarus nappe, eastern Swiss Alps. Numerical simulations are matched against well-established oxygen isotope gradients on the kilometer scale along the thrust. At internal southern locations, strongly channelized thrust-parallel fluid flow requires a high...

The understanding of the paleoenvironment during initiation and early development of deep cold-water coral carbonate mounds in the NE Atlantic is currently a focus of international research. The Integrated Ocean Drilling Program (IODP) Expedition 307 drilled the 155 m high Challenger Mound in the Porcupine Seabight (SW off Ireland) in order to investigate for the first time sediments from the...

Carbon- and oxygen-isotope ratios are commonly used to correlate shallow- and deep-marine successions. Carbon- and oxygen-isotope analyses were performed on bulk-carbonate samples from two Kimmeridgian sections of the Swiss Jura platform in order to correlate them with biostratigraphically well-dated coeval sections in the adjacent basin. On the platform, a general decrease in δ¹³C and...

Knowledge about biogeochemical processes associated with natural attenuation of chlorinated solvents in the environment is currently limited. Though processes such as sorption, volatilization or dilution may contribute to contaminant natural attenuation, in situ biodegradation is the only process leading to destructive removal of contaminants. However, the distribution of hydrological and...

The general aim of the project is to evaluate the feasibility of using compound-specific isotope analysis (CSIA) to assess biodegradation of petroleum hydrocarbons in the unsaturated zone. The first objective was to quantify the isotope enrichment factors during biodegradation of several volatile organic compounds (VOCs) commonly found on petroleum hydrocarbon contaminated sites. These microcosm...

A high-resolution stratigraphy has been developed for the interval encompassing the Cenomanian–Turonian boundary (CTBI), by means of several lithological, biological and geochemical events. This work entails the study of two sections selected on the base of the completeness of their sedimentary record and their contrasting paleogeographical setting: (1) The Rock Canyon Anticline section west of...
