The South Kyrtayel oilfield lies on the western margin of the Pechora-Kozhva Swell, a major inverted Palaeozoic rift element of the Timan- Pechora basin. The field was discovered in 1976 but is only now being developed by Bitech-Silur who obtained a

The Namibian offshore region has been studied using more than 14 300 km of new multifold seismic data to provide insights into the history of lithospheric extension in the South Atlantic. Initial subsidence related to crustal stretching began at leas

Summary The sedimentary sequence between the Gastrioceras cancellatum Marine Band and the Rough Rock in south-east Lancashire comprises a wide range of lithologies ranging from mudstone through siltstone to ripple cross-laminated and cross-bedded med

Flume experiments with medium sand confirm the increasing complexity in the shape of small-scale current ripples with increasing flow velocity for constant depth. Experiments suggest that a measure of ripple shape (the ratio of wavelengths of transve

Three main kinds of syndepositional deformation are found in cross-bedded sand-grade sediments. The first type is characterized by simple recumbent folds of broadly parabolic form. The second is marked by series of folds, with or without overturning.

The bulk of the material comprising the pocket beach at the mouth of the Manndraperelv, Tanafjord, northern Norway, is supplied by the river. The stream bed consists of poorly sorted coarse sediments which show a crude upstream imbrication. Dampening

The Duolbasgaissa Formation, Lower Cambrian, of northern Norway consists of 550 m of mineralogically and texturally mature sandstones with subordinate siltstones, mudstones and conglomerates. Four facies are defined on the basis of grain size, bed th
