Major and trace element compositions and strontium, neodymium, and lead isotopic ratios of late Cenozoic mafic lavas from the northern Basin and Range
(1992)
During the late Cenozoic mafic lavas were emplaced contemporaneously with Basin and Range extension near Battle Mountain, Nevada. They display wide ranges in major and trace elements contents and Sr, Nd, and Pb ratios. The ...
The effect of metamorphism on the trace element composition of subducted oceanic crust and sediment
(1993)
Metasedimentary and metabasaltic rocks of the Pelona schist of Sierra Pelona, southern California, preserve a relatively high P/T inverted metamorphic gradient (Graham and Powell, 1984) and provide an opportunity to study ...
Petrogenesis of late Cenozoic volcanic rocks from the Raton-Clayton volcanic field, northeastern New Mexico and southeastern Colorado
(1995)
Late Cenozoic volcanism on the Great Plains in northeastern New Mexico was closely related to the tectonic and thermal deformation along the transitional zone between the Colorado Plateau and southern Basin and Range ...
Pre-Tertiary stratigraphy, magmatism, and structural history of the Central Jackson Mountains, Humboldt County, Nevada
(1996)
The Jackson Mountains (JM) are part of the early Mesozoic continental arc in northwest Nevada, which was constructed upon previously accreted Paleozoic basement. The stratigraphy of the Paleozoic basement exposed in the ...
Petrogenesis of plutons and hypabyssal rocks of the Bering Strait region, Chukotka, Russia
(1998)
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 ...
Geology and stratigraphy of the Mount Bennett Hills, and the origin of west-central Snake River Plain rhyolites
(1990)
Voluminous mid-Miocene (8-13 Ma) rhyolitic ash-flows and lava flows (Idavada volcanics) are exposed continuously along the northern (Mount Bennett Hills or MBH) and southern margins of the west-central Snake River Plain ...
Trace element geochemistry of basalts from the Oregon Cascade Range: Implications for magma generation and possible variations in the sub-arc mantle
(1998)
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
(1995)
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 ...
Calcium carbonate dissolution patterns at intermediate water depths of the tropical oceans during the Quaternary
(1994)
This study presents mineralogic and stable isotopic records generated for piston cores and Ocean Drilling Program holes recovered from intermediate water depths (500 to 2500 meters) near carbonate platforms around the ...
The Caribbean carbonate crash at the middle to late Miocene transition and the establishment of the modern global thermohaline circulation
(1999)
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 ...
