...Bruce W. Selleck; Paul F. Carr; Brian G. Jones Abstract Calcite pseudomorphs after ikaite (glendonite) are associated with coldwater depositional systems, including glaciomarine and deepwater settings, as dictated by the limited stability field of ikaite. Ikaite precipitation is favored by elevated...

...Orville L. Bandy; Ronald L. Kolpack Abstract A quantitative study was made of the microfossil and sedimentology of most of the Tertiary section in Tecolote Tunnel, Santa Barbara County, California. Foraminiferal evidence indicates that the Cozy Dell shale and Coldwater sandstone are middle Eocene...

... was not observed in the Coldwater, Tranquille, and Chu Chua formations. Clastic shale typically contains ∼40%–60% SiO 2 in the form of detrital particles of quartz, feldspar, mica, and clay ( Clarke, 1924 ). These well-crystallized silicates produce characteristic X-ray diffraction peaks (Fig.  5 ). In shales...

... of Tillodontia and Brontotheriidae in B.C. Further, the presence of the largest species of Trogosus — T. latidens — as well as a smaller species identified only as Trogosus sp. supports a late early – early middle Eocene (Bridgerian) age for the Vermilion Bluffs Shale of the Allenby Formation. Based...

... and organic shales. In California, most of the seeps and oil sands overlie or are updip from underlying heavy-oil reservoirs. The seep and oil-sand deposits occur in areas where cap-rock integrity was compromised for the underlying heavy-oil reservoirs, breeched mainly by faults or fractures. Hydrocarbons...

... field extends up glacier from the Sturgis moraine, across the subcrop of the Mississippian Coldwater Shale, to the subcrop of the overlying Marshall Sandstone (Fig. 13 ). The low permeability of the shale may have increased basal pore pressures into a range in which deformation of basal sediment...

... is thin in the northern area of land system 1. Here, the Saginaw Lobe crossed a bedrock highland composed of the Marshall Sandstone and Coldwater Shale ( Rieck and Winters, 1982 ), and the ice was predominantly erosional. Older units are less likely to be preserved in this area outside of bedrock valleys...
