R. E. Wallace 1976 <p>The great Talas-Fergana fault transects the Soviet republic of Kirghiz in Soviet Central Asia and extends southeastward into China and northwestward into Kazakh SSR (figs. 1 and 2). This great rupture in the Earth's crust rivals the San Andreas fault in California; it is long (approximately 900 kilometers), complex, and possibly has a lateral displacement of hundreds of kilometers similar to that on the San Andreas fault. The Soviet geologist V. S. Burtman suggested that right-lateral offset of 250 kilometers has occurred, citing a shift of Devonian rocks as evidence (fig. 3). By no means do all Soviet geologists agree. Some hold the view that there is no lateral displacement along the Talas-Fergana fault and that the anomalous distribution of Paleozoic rocks is a result of the original position of deposition.&nbsp;</p> application/pdf en U.S. Geological Survey The Talas-Fergana Fault, Kirghiz and Kazakh, USSR article
