These two zones are interpreted as having been deposited on a wave dominated coast. They typify upward coarsening sequences in much of the Lower Cretaceous of northeastern British Columbia. Similar cycles have been observed in the underlying Gething Formation and overlying Boulder Creek (Paddy - Cadotte) as well as the Notikewin of Alberta.
Cores containing the Bluesky Formation and related strata of the underlying Gething Formation and the overlying Wilrich Member were systematically logged and sampled for their micropaleontological content. The various datasets were then integrated to provide enhanced paleoenvironmental interpretations. Formation of the Coast Range Plutonic Complex. Accretion of the Insular Super Terrane.

Geology The term geology comes from the Greek words “ge” (“earth”) and “logia,” meaning the study of and discourse involving the solid Earth, including the rocks of which it is composed, and the processes by which those rocks change. Geology can also refer generally to the study of the solid features of any celestial body (such as the Moon or Mars).
Lithology. The Fort St. John Group is mostly composed of dark shale deposited in a marine environment. Bentonite is present in the shale, and it is interbedded with sandstone, siltstone and conglomerates.. Distribution. The Fort St. John Group occurs in the subsurface in the Peace River Country of northeastern British Columbia and north-western Alberta, in southern Yukon and southern . The Peace River deposit comprises bitumen-rich sands from the Aptian-Albian Gething Formation, Ostracode Zone, and Bluesky Formation, which overlay Paleozoic and older Mesozoic strata.
