The ammonites of the Bukowskii Subzone of the Oxfordian of Skye
Scottish Journal of Geology, 1970Synopsis The ammonite fauna of the Bukowskii Subzone of the Cordatum Zone consists of large numbers of relatively few species of cardioceratids and aspidoceratids. The fauna of this zone in the Staffin Shales can be correlated with that of the Bukowskii subzone of the English succession, although in Skye Cardioceras

Ironstones in the Upper Oxfordian of southern England
Sedimentology, 1974The Upper Calcareous Grit, the last of the four upward shallowing cycles that comprise the Corallian Beds of southern England, is relatively enriched in iron minerals, having local developments of chamosite oolite mudstone and much more widespread deposits of sand and mud containing variable amounts of siderite and disseminated chamosite. The chamosite

Suction effects in deep Callovo-Oxfordian claystone
Géotechnique Letters, 2014An experimental programme was carried out with the aim of investigating suction effects in a specimen of Callovo-Oxfordian claystone extracted at great depth (479 m). A specimen that was saturated in an oedometer with limited swelling exhibited significant swelling and desaturation upon quick unloading at constant water content.

Oxfordian Sedimentation in Western Interior United States
AAPG Bulletin, 1974Abstract Upper Jurassic (Oxfordian) sediments of the western interior United States were deposited in part of an epicontinental seaway which extended south from the present arctic. This seaway contained a complex of tectonic elements which influenced significantly the geographic distribution of depositional environments. Sedimentation

Characterization of Dichotomoceras in the Oxfordian of Kachchh
Journal of the Geological Society of India, 2009Abstract We report here the first Dichotomoceras of the Indian subcontinent at Kantkote (Wagad) in the proximal most exposed part of the Kachchh Basin. This is further addition to the significant enlargement of the Oxfordian ammonoid record made earlier (Krishna et al. 1994, 1995, 1998, 2000). Near continuous presence of ammonoids has

THE LOWER OXFORDIAN (UPPER JURASSIC) OF NORTH YORKSHIRE
Proceedings of the Yorkshire Geological Society, 1983SUMMARY Sedimentation during the Lower Oxfordian in North Yorkshire proceeded in two contrasting phases. The first, a shallow water sedimentation phase of the scarburgense Subzone age, was succeeded by deeper water conditions as the Callovian/Oxfordian transgression reached its maximum extent and the ...

Oxfordian Sedimentation in Western Interior, USA: ABSTRACT
AAPG Bulletin, 1972Upper Jurassic Oxfordian sediments of Wyoming, Montana, and eastern Idaho were deposited in part of an elongate inland seaway extending southward from the present Arctic. This seaway contained a complex of tectonic elements which influenced significantly the geographic distribution of depositional environments.
