This work presents the results of a petrographic, mineralogical and geochemical study on one of the few known occurrences of  blueschist facies metamorphic rocks in the Variscan belt of Western Europe.The  geochronological results have been published in "Nature" ( see Carpenter and Civetta, 1976), while the trace element geochemistry of the metabasic rocks has been used to characterize the tectonic environment of the protoliths (see Bernard-Griffiths et al.., 1986).

The topic was to investigate the  geochemistry of variously metamorphosed basic igneous rocks from the Armorican Massif, France. The aim was to determine the tectonic environments of the protoliths and, ultimately, to characterize the source-regions involved in their magma genesis. The results of this study have been published in Carpenter et al. (1982), Bernard-Griffiths et al. (1986) and appear in various conference abstracts.

From Jan. 1979, an analytical programme was undertaken in collaboration with Dr A. Cocherie to obtain REE data on granitic rocks from South  Brittany. This work has led to the publication of a paper on the petrogenesis of Ordovician  trondhjemites (see Cocherie and Carpenter, 1979).


Geologist/Geochemist in the Marine Chemistry Group at the  Institute of Oceanographic Sciences, Wormley, UK. While working in this post, I was responsible for the day-to-day management and development of an X-ray analytical facility used to characterize the mineral and chemical composition of working in this post, I was responsible for the day-to-day management and development of an X-ray analytical facility used to characterize the mineral and chemical composition of  deep-sea sediments. The work was carried out to meet the demands of a research contract commissioned by the Department of the Environment on the ocean disposal of high-level radioactive waste. Sediment cores were sampled during oceanographic cruises, and the results of detailed laboratory analysis were interpreted in the light of pore-water and Th-230 activity profiles (see published results in CARPENTER et al., 1983; THOMSON et al., 1984; BOUST et al., 1988).
