Get this from a library. Mesozoic and Cenozoic Mactrinae of the Pacific Coast of North America. [Earl L Packard]. The maps are very useful but the best parts of the book are the reference section and bibliography. I'd give it a five star rating if the references and bibliography were updated to include the last decade of literature.

This is a great little book for starting some of your research in the available literature on this by: The distribution of Jurassic arcs suggests that an oceanic arc was sutured onto North America in Early Cretaceous time.

The tremendous volume of added sialic magma dilated the western edge of the continent by almost kilometers, perhaps causing the continent to override the trench at the end of the Oligocene. Full text of "A Catalogue of the Mesozoic and Cenozoic Plants of North America" See other formats.

Armentrout. Mesozoic basins of the southern Western Interior were related to complex tectonic events of the evolving Cordilleran arc and coeval Mesozoic terrane accretion to western North America.

The thickest basins are elongate N-S along the western margin of the Colorado Plateau but are abruptly truncated westward by pre-Cretaceous erosion.

Assuming that spreading existed at the same rates prior to the period of late Mesozoic reversals, and projecting it back in time, the system would have started essentially at a point in the vicinity of 15°N and °E at to ill.y.B.P.

Spreading was faster on the Kula‐Pacific and the Pacific‐Phoenix ridges than on the Pacific Cited by: But at times some may have been deflected north to the Caribbean, following lows of foreland basins such as is common in the Cretaceous of North America, where The Mesozoic and Cenozoic paleodrainage of South America: a natural history a large river system drained northward subparallel to the Mesozoic and Cenozoic Mactrinae of the Pacific Coast of North America book Rockies (McLean,Figs.

7 and 8 Cited by: It seems important for Japanese stratigraphers to recognize the present status of the Mesozoic geology in North America especially its Pacific side, since Japan belongs also to the Circum-Pacific.

Pacific Rise met the North American Plate, ~ Ma in central California, and ~ Ma in northern Mexico. It was the collision of the East Pacific Rise with the west coast of North America that created the modern San Andreas Fault system. Thus the northern San Andreas Fault system formed ~27 Ma, the southern California sectionFile Size: 3MB.

Hence, perhaps a closer look at the opening North Pacific hypothesis is warranted. This paper presents various lines of evidence which favor a Late Paleozoic rifting of cordilleran North America from East Asia, a Mesozoic drift across the North Pacific, and a Cenozoic suture to the North American by:   The geology of western North America was shaped by interaction with three major ocean plates; the Kula, Farallon and Pacific plates.

Their motion in the Cenozoic era has been inferred through careful reconstructions of relative plate movement. been common to Australia’s eastern margin and New Guinea.

This is consistent with the interpretation of Stampfli and Borel (in press) that renewed rifting along the north Australian margin of Tethys occurred in the Late Triassic, due to subduction of the Palaeo-Tethys ridge beneath Size: 2MB. Mesozoic rocks of the Cordilleran mobile belt extend to the continental margin on the southwestern Oregon coast.

The region has been eugeosynclinal since at least the early Paleozoic, but dominance of continental‐type andesites suggests the presence of essentially continental crust throughout its known by: We compiled maximal body size for two guilds of marine mammals in both the North Pacific and North Atlantic Ocean basins during the Cenozoic.

We restricted our search to fossil-bearing rock units of the western and eastern coasts of these basins, while excluding fossils from the Mediterranean region and elsewhere (see electronic supplementary Cited by: Pacific Northwest Cenozoic Biostratigraphy.
