Petrogenesis of plutons and hypabyssal rocks of the Bering Strait region, Chukotka, Russia
Subduction of an oceanic plate beneath the Bering Strait region resulted in the formation of an extensive magmatic belt along the margin of the region during the Cretaceous. Plutons and gneiss domes of this age are broadly ...
Trace element geochemistry of basalts from the Oregon Cascade Range: Implications for magma generation and possible variations in the sub-arc mantle
Analyses of Oregon Cascades basalts reveal two groups of High Cascades (9-0 Ma) lavas: (1) "enriched" basalts with high Ba, Sr, Ba/Nb, and Ba/La, and (2) "depleted" basalts with flat rare earth element patterns and relatively ...
Boron metasomatism in the Alta stock contact aureole, Utah
The effects of fluid evolution and infiltration in the Alta stock contact aureole, Utah, were studied by evaluating chemical additions and depletions in igneous, replacement skarn, and carbonate whole-rock samples. Of the ...
The Caribbean carbonate crash at the middle to late Miocene transition and the establishment of the modern global thermohaline circulation
The Caribbean carbonate crash was a time of increased regional carbonate dissolution at the middle to late Miocene transition. It is marked by five dissolution episodes, occurring from 12-10 Ma, characterized by significant ...
