• International Events

• Cover: Large tubular carbonate (dolomitic) concretions litter the shore platform south of Whangaehu Beach, eastern North Island, New Zealand. The concretions have eroded out of slope mudstones of the upper Miocene Whangaehu Formation which forms the platform and which is well exposed, together with in situ concretions, in the cliffs which stretch southwards towards Cape Turnagain. Most of the concretions support near-central conduits which are suggested to have focused the upward escape of hydrocarbon gases in a palaeo-cold seep system.

• Erratum

• International Events

• Cover: Cover image shows giant cannonball concretions in the Lower Carboniferous Marar Formation, Tinedhan Anticline, Western Libya. These calcite concretions formed within fluvial sandstones and grew during shallow burial. The Marar sandstones are potential reservoir rocks in the Ghadames Basin, and understanding the distribution of cements, which reduces the overall pore volume, is a critcal factor. See the related paper by Fröhlich et al. on pp. 3-18 of this issue. (Photograph by Sebastian Fröhlich, North Africa Research Group, University of Manchester).
