(1988): Collapse of a Hercynian Tibetan plateau into a Late Paleozoic European Basin and Range
The other half of the missing plate motion has disappeared in the Basin and Range geologic province east of the San Andreas, the geologists say.
The rotating mountains, the extending Basin and Range, and the observed San Andreas motion together explain the entire motion between the Pacific and North American plates.
Casual observation of the area indicated that the basins are grabens slowly filling with Quaternary sediments; this kind of physiography is typical of the Basin and Range Province of the United States and northern Mexico.
During and after the episodes of volcanic activity, deposition of the siltstone and conglomerate facies continued until probably Miocene or Pliocene time, when the basin was uplifted by block-faulting that affected much of the Basin and Range Province in the southwestern United States and northern Mexico.
The latest blow to the textbook account comes from an analysis of fossil leaves in Nevada's Basin and Range
geologic province, which separates the Sierra Nevada from the Rocky Mountains and the Colorado Plateau.
The Basin and Range
province, as all geology students learn, is an area of the western United States predominantly Nevada and western Utah - that plate-tectonic forces have stretched and thinned, producing a distinctive landscape that lives up to its name.
In addition to the northwestern Cordillera, sharp, flat and highly reflective Mohos are seen in the Basin and Range
Province, the continental shelf around Great Britain, the Paris basin and the U.S.
In eastern California, earthquakes occur in the "basin and range
" faults that lie alongside the mountain ranges, Corbett says.
At the AGU meeting, Minster presented the results of recent modeling and data indicating that the deformation across the Basin and Range
region to the east of the San Andreas is about 0.7 cm/yr -- too small and in the wrong direction to account for the discrepancy.
