... of relative sea-level rise. A well-exposed example is the Cape Sebastian Sandstone, a 200-m thick, fining-upward sequence representing foreshore to offshore deposition. Progressively increasing depth of deposition is indicated by both physical and biogenic sedimentary structures in the Cape Sebastian...

... of relative sea-level rise. A well-exposed and convincingly documented example is the Cape Sebastian Sandstone, a 250-m-thick, fining-upward sequence representing foreshore to offshore accumulation. Progressively increasing depth of deposition is reflected in both physical and biogenic sedimentary structures...

...Ralph E. Hunter; Edward H. Clifton Abstract Cyclic deposits containing hummocky cross-stratification occur in the upper part of the Cape Sebastian Sandstone of Bourgeois (1980), a shallow marine transgressive sandstone of Late Cetaceous age on the southern Oregon coast. The cycles average 1.6 m...

Although very low-angle tangential laminae are not uncommon, their relationship to the lower bounding surface is typically one of onlap. Several well-exposed hummocks in the Cape Sebastian Sandstone and Coaledo Formation, southwest Oregon...

... disappearing leaves the prospects for its making a good reservoir rock rather dim, even though it has marine shales above and below. It also is found in the wells at Manantiales, San Sebastián, and Espora, in which localities it is a very fine-grained, very glauconitic, shaly sandstone. Its age may...

Other examples of transgressive shelf systems without sand ridges are discussed by Galloway and Hobday (1983) and Walker (1985a) . Although the Cottage Grove is similar to some shelf...

Thus, in certain situations (e.g. the Upper Cretaceous Cape Sebastian Sandstone of the Oregon coast) hummocky cross-stratified sandstone facies can occur in amalgamated units up to 75 m in thickness (cf. Bourgeouis, 1980 ). Such thick accumulations of hummocky cross-stratified sandstone...
