Dear Frank Pawellek, 

        Prof. Eric Mountjoy and myself are holding a grant from which we can
hire a postdoc for a year, maybe 18 months. The person of choice should be
conversant in stable and radiogenic (Sr) isotope work on carbonates and
sulfates. We are working on dolomitized and petroliferous carbonate
platforms and reefs in western Canada, mainly on diagenetic problems. Our
postdoc would be based in Montreal at McGill University, and some travel to
Calgary, Edmonton, and the Rocky Mountains would be part of the job.

        If any or all of this looks interesting to you, please get in touch
via e-mail with Eric. He'll be out of Montreal until June 07, so don't
expect an immediate answer. I just talked to him on the phone, and I told
him that you may get in touch. I am forwarding this message to him.

        Cheers, 

        Hans G. Machel

P.S. If you come to Sediment '95 in Freiberg, please try to find me so we
can talk. I'll be there.

>Hi, I am Frank Pawellek, currently working at the Isotope labs of the
>Ruhr-Universitaet in Bochum/Germany (Prof. Dr. Jan Veizer). During the last 4
>years, I have been doing my PhD there. It concerned the application of stable
>isotopes (O, H, C, S) + 87Sr/86Sr to questions concerning river water. The main
>purposes were 
>1. to find out more about the origin and fate of riverine dissolved inorganic
>carbon ( organic matter, carbonate dissolution, uptake from atmosphere,
>influence of photosynthesis and riverine bacterial degradation processes...) 
>2. the same for dissolved sulfate (evaporite dissolution, sulfide oxidation,
>acid precipitation, extent of riverine bacterial sulfate reduction...) and 
>3. the influence of watershed geology on Sr-isotope ratios. I investigated the
>upper 1000 kilometers of the river DANUBE + 20 of its major tributaries.
All the
>sampling and lab work has been done so far, the PhD-paper is finished and I am
>now waiting for the outcome. Anyway, I am using the time to prepare some
>publications. There are some nice results concerning S-isotopes in sulfate and
>the origin of the sulfate, especially  the influence of acid precipiation. Its
>not a big thing, but worth publication, I think. Does anybody have an idea of a
>well suited journal for something like that? It is somehow on the borderline
>between isotope geochemistry and environmental geochemistry.
