Pre-Tertiary stratigraphy, magmatism, and structural history of the Central Jackson Mountains, Humboldt County, Nevada
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 ...
Major and trace element compositions and strontium, neodymium, and lead isotopic ratios of late Cenozoic mafic lavas from the northern Basin and Range
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 ...
Calcium carbonate dissolution patterns at intermediate water depths of the tropical oceans during the Quaternary
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 effect of metamorphism on the trace element composition of subducted oceanic crust and sediment
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
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 ...
Geology and stratigraphy of the Mount Bennett Hills, and the origin of west-central Snake River Plain rhyolites
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 ...
