The Southern Urals of Russia contain what is arguably one of the best-preserved examples of an arc–continent collision in any Paleozoic orogen. The arc–continent collision history recorded in the rocks of the Southern Urals began in the Early Dev

We propose a numerical method for modeling the geochemical evolution of nonsteady state (changing volume) magma chambers using analyses of erupted lavas. The method allows estimation of the ratio between concentrations of an incompatible element in t

In the southern Urals, the allochthonous ophiolite belt at the junction between the Uralides and the East European continental margin includes lherzolite (Kraka, Nurali, Mindyak, etc.) and harzburgite, or lherzolite-harzburgite (Khabarny, Kempersay,

The objective of the Naudur cruise (December 1993) of the submersible Nautile was to study the interaction among magmatic, tectonic, and hydrothermal processes at a very fast spreading mid-ocean ridge axis. Twenty-three dives were completed, both alo

Holes were drilled at three Sites in the Sulu Sea on Ocean Drilling Program Leg 124. Site 768 lies in the deeper part of the SE sub-basin and Sites 769 and 771 lie on the flanks of the Cagayan ridge. The results indicate that the Sulu Basin originate

Leg 124 of the Ocean Drilling Project drilled Sites 767 and 770 in the northern Celebes Sea, reaching late middle Eocene basaltic basement at both sites. Major shifts in sediment provenance record the changing tectonic setting of the basin. From late
