The captured plate then acquires the motion of the plate it welded to. In the southwest Pacific the Pacific-Phoenix ridge approached the east...

The sequence of undisturbed sediments on top of the compressional structure suggests a tectonic event between 50 and 13 Ma, while relative motion between the Antarctic-Bellingshausen plate and the Phoenix plate had already begun in the Late Cretaceous. We suggest...

... The Caribbean Plate was created as the North and South American Plates began to separate about 140 m.y. ago, allowing the Phoenix/Farallon spreading ridge to extend eastward. The Caribbean Plate was separated from the Phoenix/Farallon spreading ridge, about 110-100 m.y. ago, by a subduction...

This article examines extrapolations specifically using modes 2 and 3, employing the known spreading histories of the Pacific-Farallon/Vancouver and Pacific-Phoenix plate systems and the Tasman Sea as case studies...

These oceanic sediments and their basaltic substrates were evidently emplaced in the Torlesse accretionary prism following off-scraping from an extensive subducting oceanic plate, probably the Phoenix plate, which was obliquely convergent with the northwest-trending Gondwana margin during Late Jurassic...

... coast of Graham Land. This geographical distribution could be explained by (1) a flat slab with east-dipping subduction of the Phoenix Plate, or (2) west-dipping subduction of the lithosphere of the Weddell Sea, or (3) an allochthonous origin for the rocks of Alexander Island. A better understanding...
