Zircon Geochronology of Volcanic Rocks from the Trans-Pecos Orogenic Belt, Western Texas: Timing the Cessation of Laramide Folding, Uplift, and Post Flat-Slab Ignimbrite Flare Ups
This study refines regional differences in the cessation of Laramide compressional deformation and the subsequent initiation of episodic slab-asthenosphere influenced ignimbrite-rhyolite volcanism in West Texas by utilizing ...
Paleosol evolution in a sequence stratigraphic framework, Cretaceous Ferron Notom Delta, south central Utah, U.S.A.
Hydromorphic paleosols have been previously thought of as ever wet and poorly developed, and lacking useful paleoenviromental and paleoclimatic indicators. However, a suite of pedogenic features and geochemical attributes ...
Cenozoic basin evolution of the Virgin Islands basin and Anegada Passage, northeastern Caribbean
The Virgin Islands basin (VIB) is a 1 to 4.5 km¬‐deep, fault‐bounded marine passage that forms the southwestern and deepest segment of the Anegada Passage connecting the Atlantic and Caribbean Seas. A variety of models ...
CENOZOIC STRUCTURE, STRATIGRAPHY, AND PALEOGEOGRAPHY OF THE LOWER MAGDALENA BASIN, COLOMBIA
The structural and stratigraphic evolution of the Lower Magdalena Basin (LMB), located in northwestern Colombia, remains controversial with several tectonic models proposed to explain its origin and development. LMB covers ...
