• Main photograph shows a quarry wall composed of marls of the Badenian (mid-Miocene) Moslavacka gora Formation (including organic-rich intervals) near Našice, eastern Croatia. Bedding here generally dips at low angles, but close-up photographs (see insets) show domino-style micro-faulting with relatively steeply dipping lamination. A subsurface structural interpretation of the Moslavacka gora and overlying formations, based on diplog data from wells in the Drava Depression, is the subject of the paper by Velic et al. on pp. 343-356. Photographs by Marko Cvetkovic.

• The tight Danian Ekofisk chalk reservoir formation in the South Arne field, North Sea: mineralogy and porosity properties
  H. Lindgreen (GEUS, Denmark), A. E. Fallick, F. Jakobsen and N. Springer view abstract
• International Events
• Cover: Photo to right shows a core tray from a well in South Arne field, Danish North Sea. Cores are composed of Danian chalk of the Ekofisk Formation, a reservoir unit of secondary but increasing importance. Porosity and permeability in the chalk are reduced by the presence of both clay minerals and detrital nano-sized quartz, as illustrated in the SEM image (left, above) and the atomic forced microscopy image (left, below). See the related paper by Lindgreen et al. on pp. 291-310 of this issue. Photos by Holger Lindgreen (Geus, Denmark).

• Potential petroleum source rocks in the Termit Basin, Niger

• Chemostratigraphy of Cenomanian-Turonian carbonates of the Sarvak Formation, southern Iran

• International Events
• Cover: Cover photo shows coastal cliffs composed of steeply dipping Lower Jurassic carbonates to the north of S. Pedro de Moel (Lusitanian Basin, western Portugal). At this location, the Coimbra Formation, here dominated by Upper Sinemurian bioclastic limestones, is overlain by organic-rich facies of the Água de Madeiros Formation. The source rock potential of the latter formation is the subject of the paper by Duarte et al. on pp. 105-126 of this issue. Photo by L. V. Duarte.

• Cover: Main photo shows Eocene limestones of the El Garia Formation exposed at the El Garia type locality in northern Tunisia. Mid-Eocene nummulitic grainstones form important reservoir rocks for hydrocarbons in North Africa. Equivalent limestones in the Sirt Basin (Libya), known as the Gialo Formation, are the subject of the paper by Swei and Tucker on pp. 25-48 of this issue. Below are field photos of the El Garia Formation (left and centre); and a photomicrograph of a nummulitic facies in the Gialo Formation. Photos by Paola Ronchi except bottom right by Maurice Tucker.
