  author={John A. Tarduno and Michael O. Mcwilliams and Michel G. Debiche and William V. Sliter and M. Clark Blake},
The Calera Limestone, part of the Franciscan Complex of northern California, may have formed in a palaeoenvironment similar to Hess and Shatsky Rises of the present north-west Pacific1. We report here new palaeomagnetic results, palaeontological data and recent plate-motion models that reinforce this assertion. The Calera Limestone may have formed on Farallon Plate plateaus, north of the Pacific–Farallon spreading centre as a counterpart to Hess or Shatsky Rises. In one model2, the plateaus…

Collision of the Caribbean Large Igneous Province with the Americas: Earliest evidence from the forearc of Costa Rica
The Cretaceous period was marked by the most voluminous episodes of oceanic plateau volcanism in the Phanerozoic Eon. Primarily affecting the Pacific, mantle plumes generated oceanic plateaus during
Subduction and accretion of the permanente terrane near San Francisco, California
Previous studies of the Calera limestone (Permanente terrane, Franciscan complex) of California have shown that deposition occurred at approximately 25°N paleolatitude atop an oceanic plateau or
On Resolution Guyot, in the Mid-Pacific Mountains, two major intercalations of oolitic limestone have developed, one of latest Hauterivian-Barremian age, which rests directly on edifice basalt, and
Southern Hemisphere Origin of the Cretaceous Laytonville Limestone of California
New paleomagnetic, paleontologic, and stratigraphic data from outcrops of the Laytonville Limestone support a Southern Hemisphere origin and brings into question the validity of a "speed limit" for absolute plate velocity based on present-day plate motions.
Geochemistry of upper Palaeozoic ‘thin-layer’ limestones in the southern North China Craton: implications for closure of the northeastern Palaeotethys Ocean
Abstract During the late Palaeozoic Era, a series of related marine strata dominated by multi-layer limestones were deposited in the southern North China Craton. In order to gain new insights into
Temporal changes in geothermal gradient, Franciscan Subduction Complex, northern California
The Franciscan Complex comprises several tectonostratigraphic terranes that were accreted to coastal northern California during late Mesozoic to Miocene time. Estimates of peak paleotemperature

Palaeomagnetic data from Permian, Triassic and Jurassic bedded rocks, to which attitudinal corrections can be applied, yield palaeolatitudes concordant with those of ancestral North America, but very
Palaeoceanography of organic‐rich rocks of the Loma Chumico Formation of Costa Rica, Late Cretaceous, eastern Pacific
The Late Cretaceous (late Cenomanian-Campanian) Loma Chumico Formation consists of laminated to massive bedded siliceous shales, cherts, ash fall tuffs/volcanic glass beds and volcaniclastic


Franciscan Complex limestone deposited at 24°N
Limestone and diabase from 11 sites in the Permanente Quarry, the largest outcrop of Calera limestone in the Franciscan terranes, have been studied by paleomagnetic and biostratigraphic methods.
Was the Laramide orogeny related to subduction of an oceanic plateau?
Numerous models have been presented to explain the late Cretaceous/early Cenozoic Laramide orogeny, which affected the foreland region of the western cordillera within the US1. The most attractive

Mesozoic aseismic ridges on the Farallon Plate and southward migration of shallow subduction during the Laramide Orogeny
We propose that an aseismic ridge of Late Jurassic and Early Cretaceous age on the Farallon plate was subducted beneath the Unites States Cordillera during the Laramide orogeny. The relative buoyancy

Directions of magnetization observed from rock-units from a given continental block are conveniently summarized by a path of apparent polar wander (apw) relative to that block. This article documents
