    Notes: Abstract An interdisciplinary approach based on high-resolution physical stratigraphy, biostratigraphy, organic matter analysis and clay mineralogy has been applied to the mixed siliciclastic/carbonate Kimmeridgian/Tithonian deposits of the Boulonnais (north-western France). These rocks are the age-equivalents of some of the offshore marine source rocks of the North Sea and were deposited in an overall storm-dominated homoclinal ramp setting which may represent one of the most shore-proximal sediments of this age cropping out in north-western Europe. Comparison with data from the Yorkshire, Dorset, Lorraine and Aquitaine areas allows the discrimination of three major transgressive-regressive sediment packages with disconformities of interregional extent: (1) from the Baylei Zone to top Eudoxus Zone; (2) from the Autissiodorensis Zone to base Scitulus Zone; (3) from the upper Scitulus Zone to the Pectinatus Zone. The lower two regionally correlative disconformities correspond to the sequence boundaries at the top of the Eudoxus Zone and the top of the Autissiodorensis Zone, formed by high-frequency relative sea-level variations during the periods of maximum transgression of the platform. The latter disconformity (the P1 nodule bed) reflects a major tectonically induced reorganization of the north-west European intrashelf sedimentary basin, characterized by a shift in both the location of the main depocentre and the sources of sediment production.

    Kinetics of spreading of photodamaged DOPC liposomes at the air-water interface (1995)

    Notes: Abstract The kinetics of surface film formation from DOPC small unilamellar liposomes spread at the air-water interface was studied. A simple theoretical and experimental approach was used. It was found that the surface transformation process was accelerated under photodynamic lipid peroxidation in presence of methylene blue and red light illumination. A theoretical approach, coupling the photodynamic action and the process of spreading of liposomes was developed. The mechanisms of photomodification and destabilization of the liposomal bilayer structures was analyzed.
