Marine Geology, 1994
Abstract The ages and average sedimentation rates of four long sediment cores from the Norwegian-Greenland Sea were determined by using various 230 Th dating models. The results were then related to an independent time control ( δ 18 O stratigraphy) which was available for the cores under consideration.

Sequence Stratigraphy of the Cambrian and Ordovician Series in the Illizi Basin (Algeria)
2014The Cambro–Ordovician sediments of the Southeast Saharan Platform show a facies evolution from continent to platform rather than from platform to basin and, for that reason, faciological stratigraphy (Homewood et al. 1992) has been applied. The genetic sequences are limited at their bases and tops by Maximum Flooding Surfaces (MFSs).

Sequence stratigraphy and micropaleontology of the Triassic series from the southern part of Tunisia
Journal of African Earth Sciences (and the Middle East), 1993Abstract The Triassic series in the southern part of Tunisia, only known from the oil exploration wells in the Kirchaou area (sandy series from Early Scythian to Ladinian) and in its Djeffara/Dahar-North outcrops (alternating series from Ladinian to Rhaetian) is now subdivided into 10 Depositional Sequences (DS) sensu Vail et al.

The stratigraphy and tectonics of the Manx Slate Series, Isle of Man
Quarterly Journal of the Geological Society of London, 1963The geosynclinal sequence of the Manx Slate Series has been subdivided into eleven distinct formations with a thickness of about 25 000 ft. This thick sedimentary pile was deposited in the Caledonian geosyncline and is most probably all of Cambrian age. The stratigraphical positions of two thick sheets of slump-breccia have been established.

The Stratigraphy of the Siwalik Series in the Northern Potwar, Punjab, Pakistan
Quarterly Journal of the Geological Society of London, 1951Summary Detailed mapping of the Jhamat area in the west and of the Soan syncline in the east forms the basis of revision of the stratigraphy of the Siwalik Series in the northern Potwar region. The succession is here affected by facies changes of regional significance :— 1.

The stratigraphy of the Great Estuarine Series (Middle Jurassic of the Inner Hebrides)
Transactions of the Edinburgh Geological Society, 1962The successions in the Great Estuarine Series in Northern and Southern Skye, Raasay, Eigg, Muck, Ardnamurchan and Mull are described and correlated. The limits of the Series are defined in each area, and the evidence for its age in the standard zonal scheme is reviewed.

Stratigraphy and Correlation of the Indravati Series (Purana Group) of Bastar Dt. (M.P.)
Journal Geological Society of India, 1963Abstract The sequence of the Purana formations of Bastar, in the ascending order of (1) Tiratgarh subarkose and orthoquartzite, with purple shale towards the top, (2) Kanger grey laminated limestone, and (3) Jagdalpur purple shale and shale-limestone, with intercalations of quartzites and limestones, in one conformable series, is ...

The stratigraphy and palaeontology of the 'Keuper' Series of the central Midlands of England
Quarterly Journal of the Geological Society of London, 1970A reappraisal of the stratigraphical status of the formations constituting the series traditionally termed 'Keuper' in central England is given, based on palaeontological and sedimentological evidence. The 'Keuper' Sandstone is a fluvial facies representing a sub-aerial deltaic environment and is of upper Scythian and Anisian age.

Stratigraphy of Barail Series in Southern Part of Shillong Plateau, Assam, India: GEOLOGICAL NOTES
AAPG Bulletin, 1965The Barail series (Oligocene), which includes the major petroleum reservoir rocks of India, has generally been considered to be absent in the southern part of the Shillong plateau. Palynologic investigations of samples from the Tertiary section exposed in the Simsang river region and elsewhere along the south margin of the plateau indicate that ...
