• Cover photo: The photomicrographs on the cover show petrographic and diagenetic features (including cement generations and fractures) of bioclastic packstones from the Barremian – Albian "Urgonian" limestone succession in SE France. Controls on reservoir properties in these limestones are discussed by Cochard et al. in the paper on pp 97-114 of this issue. Photos by Jean Cochard.
