... tectonics thinned the Tyrrhenian side of the Apenninic Chain and formed the Lunigiana and Vara Valley grabens. The two asymmetric grabens, separated by a horst (Bernini, 1991), formed a thin-skinned extensional structure that detach above the "basement" (figs. 12 and 21) reached in the well Pontremoli 1...

We performed detailed sedimentologic and ichnologic analyses and measured stratigraphic thicknesses at Isla El Manzano, Caleta Ayacara, and Isla Ica (figs. 2 , 3 ), where the unit...

...Richard L. Mauger ABSTRACT The Calera-del Nido block extends north from Chihuahua City for 140 km and from Highway 45 west to the next major valley. The block has a steep east-facing scarp and more gentle west-facing slopes. In Majalca Canyon, a rhyolite flow dome (oldest), rhyolite tuff, boulder...

Beginning with the Oxfordian, radiolarian- rich sediments became...
