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 ...
Late Quaternary periplatform sediments and environments on the northeastern Nicaragua Rise, Caribbean Sea
Four main factors control the accumulation of periplatform sediment on the northeastern Nicaragua Rise: (1) input of carbonate sediment; (2) input of siliciclastic sediment; (3) physical redistribution of sediment; and (4) ...
Structural development and kinematic history of ramp-footwall collapse in the Doonerak multiduplex, central Brooks Range, arctic Alaska
The Doonerak multiduplex of the central Brooks Range fold and thrust belt in arctic Alaska developed during footwall collapse beneath the Amawk thrust, which underlies the Endicott Mountains allochthon. The Endicott Mountains ...
Tectonics of western Venezuela
The Mesozoic-Cenozoic tectonic evolution of western Venezuela occurred in five major stages; (1) Jurassic extension was superposed on peneplaned Late Paleozoic folded-belts. NNE-trending half-grabens developed in a back-arc ...
