Differences between Paleozoic Asia and Paleozoic North America as shown by the distribution of ultrahigh-pressure (UHP) terranes
چکیده انگلیسی

Numerous UHP suites developed in East Asia during the Paleozoic because subduction occurred in an area of low thermal gradients. By contrast, no Paleozoic UHP suites formed in North America or in terranes accreted to it because all subduction under accreting terranes occurred in an area of high thermal gradients centered in North America. High thermal gradients beneath North America are also demonstrated by an abundance of intracratonic rifts and basins. These differences in thermal gradients between North America and East Asia may have been caused by a very large mantle convection cell, with a rising limb under North America and a descending limb in an oceanic area where East Asia was assembled.
