K-Ar ages of approximately 155 m.y. were measured on minerals from ophiolites at two localities in the California Coast Ranges. Upper Jurassic rocks of the Great Valley sequence are n i depositional contact with underlying ophiolites, which are interpreted as Mesozoic oceanic crust that formed ...
Mid-ocean ridge volcanism supplies vast masses of mantle material, forming new oceanic crust. In recent years, comprehensive study has been made of such processes. The problems of geochronology have an important place in these investigations, since only a study of the events in their time ...
The age of the Banda Sea is critical for palaeogeographical reconstructions of eastern Indonesia. Assumed ages for its formation range from Mesozoic to Neogene1–10. However, geophysical evidence shows that the Banda Sea is floored by oceanic crust11,12 with a minimum age of Eocene4. Evidence ...

are challenging to constrain due to subduction of oceanic crust into the mantle, subduction flux reconstructions from full-plate models suggest sustained decline in outgassing rates throughout the LPIA29, providing a plausible alternative mechanism. Diminished radiative forcing from sulfate aerosols may hav...
Constraints on processes affecting the origin of oceanic crust: Geochemical evidence from the 0-35 M. Y. age basalts, between 30°N and 40°N, MARConstraints on processes affecting the origin of oceanic crust: Geochemical evidence from the 0-35 M. Y. age basalts, between 30°N and 40°...
Considering regional tectonic sedimentary evolution and previous research results, the authors hold that the volcanic rocks of the Qushenla Formation were probably related to the slab break-offduring southward subduction of the Bangong Co-Nujiang oceanic crust in the Early Cretaceous, and were ...
