.../Mississippian Exshaw Formation (E) and the Lower Cretaceous Ostracode Zone (Q). The most biodegraded Family EQ oils occur in the eastern part of the study area, and in stratigraphically younger reservoirs (McLaren, Lloydminster sandstones). The least biodegraded oils are present in older reservoirs (Dina...

.... It is succeeded south of the Newport Sands Fault by the Cwm yr Eglwys Mudstone Formation of clingani to linearis biozones age. North of the fault the Cwm yr Eglwys Mudstone Formation is replaced laterally by the northwards-thickening, sandstone turbidite-dominated Dinas Island Formation ( clingani and linearis...

... this valley, which is bounded to the north and south by Devonian and Mississippian carbonates and minor clastics. During lower Mannville time, clastics prograded from east to west in a dominantly fluvial environment. These clastics are preserved as the Ellerslie Formation and its equivalent, the Dina Member...

...Gislain B. Madiba; George A. McMechan Abstract We thank Dina Simin for his perceptive reading of our paper ( Madiba and McMechan, 2003 ) in which he detected a well-tie error. As one of us mentioned to him when he first drew this to our attention, we only wished he had been able to read it before...

... and are generally recognized by operators in the area. The basal formation, the Dina, is predominantly a coarse-grained fluvial sandstone sequence which infilled topographic lows on the Paleozoic surface. It is equivalent to the Lower Mannville of the central Alberta basin. The Cummings, Lloydminster, Rex, GP...

...June E. Rapson Coarse-grained clastic rocks at the top of the Kootenay formation and the base of the Blairmore group are transitional between the Jurassic and Cretaceous systems in the westerly regions of the area. The subsurface equivalents in the easterly regions of the area occur at the base...

... of tides is also notable in the strata studied at Winter, with variable tidal ranges speculated for the shallow seaway (e.g. Smith, 1988 ). A complicated stratigraphic architecture is expected, and is well-documented for the Dina-Cummings deposits, the McMurray Formation (e.g. Strobl et al., 1997a...

... [SN 049 397], along the coast between Newport and Dinas Island: oxic, mottled Peny-raber Mudstone Formation (TVDB 02-224) with phosphatic nodules (TVDB 02-226); Section D, Newport Sands, D. clingani Biozone (TVDB 02-229), locality 10 of Williams et al. (2003) ; Section E, Frongoch quarry...

... and the presence of trace fossil casts on the bases of the sandstones show the upper part, up to 150 m, of the formation to be oxic and coeval with the enveloping Derwenlas Formation. No graptolite faunas have been recovered from the Dinas Formation, but its stratigraphic relationship with the enveloping sediments...

... Cretaceous) with the possibility that the Dina Member may be early Albian. The dating is based on the faunal and floral content of the Mannville rocks, regional correlations with more fossiliferous strata, and stratigraphic position below the Joli Fou Formation. Several authors have reported marine...

... Tongue near the Highwood Dina 1 well. Two sandstone and shale units are present in wells adjacent to Highwood Dina 1, for example, in the Imperial Greenglade No. 1 (5–16–41–1W4; Fig. 6 ). They are at similar distances above sea level to the outcrop of the Ribstone Creek formation described...

...-marine gray shale, quartz sand, coal seams, and a marine shale member with a thickness of 0 to 90 feet. Locally one may divide the Mannville formation into six members here named as follows in order of increasing age: the O’Sullivan, Borradaile, Tovell, Islay, Cummings, and Dina members ( Fig. 3...
