The Zuni Sequence: Middle Jurassic—Upper Cretaceous

1987
Craton. The Zuni cratonic sequence contains strata ranging in age from Early Jurassic (Sinemurian) through latest Cretaceous (Maestrichtian). The principal areas of Zuni sedimentation were: in the western craton and Cordillera, reaching from Alaska to Mexico; on the eastern continental margin, where the Atlantic Coastal Plain first developed during ...

Revised Middle–Upper Jurassic strontium isotope stratigraphy

Chemical Geology, 2017
Abstract A study is conducted to supplement the uppermost Lower Jurassic–lowermost Cretaceous marine strontium isotope dataset and to present new statistical fits of the Middle–Late Jurassic seawater strontium isotope curve based on a numerical time scale and a detailed biostratigraphical zonal scheme.

Upper Jurassic Rocks Beneath the Bristol Channel

Nature, 1963
THE first results from a geological survey of the floor of the Bristol Channel, carried out during the spring of 1960, have already been reported1. Jurassic rocks were found “from the Holms westwards to beyond Ilfracombe” which were thought to be of Liassic age, but macrofaunal evidence was scanty and no estimate could be made of the extent of the ...

New Jurassic cycads from the Upper Amur

International Geology Review, 1965
A collection of fossil plants from Jurassic rocks in the Upper Amur basin, U. S. S. R., provides the basis for description of a new genus and two new species of fossil cycads. Butefia, n. gen., is erected to accommodate certain leaf forms previously included within the confused circumscription of the genus Glossozamites.

The Jurassic faunas of the Canadian Arctic, middle and upper Jurassic, ammonites

1961
Middle and Upper Jurassic faunas have a wide distribution in the Canadian Arctic. The following index ammonites indicate the presence of various stages: Leioceras opa/inum, Pseudolioceras m'c/intocki (see Frebold, 1960) , and Erycites cf. E. howelli (lower Bajocian) ; Cranocephalites borealis and C. warreni n. sp.

Observations on Well-bedded Upper Jurassic Limestones

1982
Some studies of selected limestone beds in the Oxfordian of the northern and southern Franconian Alb again confirm the SEIBOLD-model: A continuous deposition of detrital clay is superimposed by a periodical changing calcium carbonate production. On this base, fused (i.e., doubled) limestone beds are recognizeable. Fusion or splitting of beds depends on
