...Daniel R. Suchy; Colin W. Stearn Abstract The grouping of areas of outcrop of Lower Silurian reefs along a stretch of the Attawapiskat River west of James Bay (northern Ontario, Canada) is controlled by a conjugate set of faults striking approximately 60 and 280°. The faults are evident...

... that two sequences, bounded by regional disconformities, are present: (1) the Severn River Formation and (2) the Ekwan River and Attawapiskat formations, and possibly part of the Kenogami River Formation (listed in ascending order). Initial onlap of marine facies at the base of the Severn River Formation...

...Daniel R. Suchy; Colin W. Stearn Abstract Outcrop exposures along the Attawapiskat River in the Hudson Bay Lowlands of northern Ontario clearly reveal the morphology of Silurian (upper Llandoverian) reefs of the Attawapiskat Formation and the relationships between reef cores, flanking beds...

...Jin Jisuo; Paul Copper Abstract Reexamination and serial sectioning of the type material of Reticularia septentrionalis Whiteaves 1904 and Meristina expansa Whiteaves 1904, from the Silurian (upper Llandovery) Attawapiskat Formation, Ekwan River, Hudson Bay Lowlands, indicate that they belong...

... by Robert Bell 3 in 1885 when he explored the Attawapiskat River in the James Bay Lowland area for the Geological Survey of Canada. In his own words— For … twenty-three miles, the river flows southeast, … is generally wide and smooth, with low banks, composed of drift, while flat-bedded...

..., with Caution Creek and Chasm Creek Formations; and Red Head Rapids Formation; and the Silurian Port Nelson, Severn River, Ekwan River and Attawapiskat Formations. The high Silurian Kenogami River Formation, the Devonian Sextant, Abitibi River, Williams Island and Long Rapids Formations, and the Cretaceous...

.... However, no bioherm was noted in the areas adjacent to Golf ( Fig. 3c ). The ground surface at the Control site grades gently towards the Attawapiskat River c . 600 m to the north ( Fig. 3d ). Geophysical data (DeBeers, unpublished) suggest that there is no kimberlite in the vicinity of the Control site...

... the Victor Mine in the Moose River Basin was examined for conodont biostratigraphy and carbonate carbon (δ 13 C carb ) isotope chemostratigraphy to provide a detailed chronostratigraphic framework for the Silurian strata (Severn River, Ekwan River, and Attawapiskat formations) in the Moose River Basin...

... part of the basin succession comprises approximately 600–1040 m of Upper Ordovician (Bad Cache Rapids and Churchill River groups and Red Head Rapids Formation) and Lower Silurian (Severn River, Ekwan River, Attawapiskat and Kenogami River formations) strata. These formations mainly comprise carbonate...
