...I. Evans; C. G. S. C. Kendall; J. C. Butler Abstract During Liassic time, carbonate sediments were deposited in a northeast-southwest oriented marine trough that now forms part of the High Atlas mountains, Morocco. Shelf and deep basin deposits of this trough consist of marls, micrites and marly...

...A. Bein Abstract The Turonian shelf edge, which delimited a large carbonate shelf platform, closely corresponds to the present-day shoreline of Israel. A NE-trending shelf basin, over 30 km long and about 5-10 km wide, had been cut into the shelf rocks during the regression which terminated...

... history was inferred for each formation on the basis of petrography, clasticity and sedimentary structures. The Johnnie Formation fines upward, which suggests a marine transgression or change from open to partially restricted shelf environments. The Stirling Quartzite coarsens upward and consists largely...

...M. R. DOBSON; P. GARRETT; J. R. HAYNES; D. GRAHAM JENKINS; A. H. MEDANI Abstract Dredged carbonates from the margins of Rockall Trough mostly represent hard grounds made up of outer shelf benthonic skeletal assemblages and pelagic ooze. Chertification and occasional iron impregnation either...

... assemblages varied from estuarine–nearshore fauna in the older sediments to the outer shelf-normal marine faunas in the surface sediments. Planktonic foraminifera were found in all levels of the cores.The faunal evidence indicates that during the Late Wisconsin sea-level minimum and the period of glacial...

... shelf or low intertidal environment that was subject to periodic storm influxes. The age of the Waweig Formation is suggested to be uppermost Ludlow – Pridoli (?Pridoli). On décrit ici une nouvelle localité fossilifère dans la formation de Waweig dans le sud-ouest du Nouveau-Brunswick. L'assemblage...

...W. E. Galloway Abstract The Copper River has prograded a marine dominated fan-delta onto the deep, tectonically active northern shelf of the Gulf of Alaska. The morphology and internal stratigraphy of the delta system are products of the sporadic influx of great volumes of bed load sediment...

...) shallow basinal limestones and sandstones transitionally overlain by (2) shallow-shelf skeletal micrites, (3) oolite or coated-grain calcarenite-bar deposits, (4) lagoonal dolomitized pelletal lime mudstones and interbedded sandstones, and finally (5) intertidal algal-flat and supratidal salt-flat (sabkha...

... are herein interpreted to be sublittoral sheet sandstones, deposited in a shallow-marine shelf association. Interbedded conglomerates resulted from debris flows activated by rifting along fault scarps. The Ordovician Ouachita trough is reinterpreted as a shallow basin underlain by granitic crust. The Crystal...

.... To accommodate the sediment, the continental shelf experienced short periods of rapid strain. This activity was penecontemporaneous with phases of rapid sediment accumulation previously identified in cratonic basins; attention is drawn to the possible geodynamic significance of this apparent synchrony...

.... Lithologic and structural data have been reorganized according to an earlier field-based paleoenvironmental classification. Higher ranked structures and coarser sediments were significantly abundant in the delta front and distributary bar environments but significantly rare in the open shelf and prodelta...

... is grain supported and contains a varied amount of quartz silt. Bedding units tend to be regular and laterally continuous. Burrowing is common and cross-bedding is present especially in sparry rocks. Fusulinids are believed to have lived in an open-marine shelf environment of near normal salinity...

...; feldspar, 11; polycrystolline quartz, 10; chert, 13; and clay matrix, glauconite, and chlorite, 15 percent. The Sussex represents a prograding sequence of sand that was transported southeastward by low-flow-regime currents along a relatively shallow, marine shelf. Bioturbation, strotigraphic position...
