A 20,000 year flowstone record of Gulf of Mexico sourced moisture in Texas
(2016-05)
Understanding how future atmospheric warming may affect moisture distribution in the American Southwest is becoming increasingly important. To this end, various paleoclimatic proxies have been used to investigate the range ...
Geochemical and geochronological relationships between granitoid plutons of the Biga Peninsula, NW Turkey
(2012-05)
The Aegean Sea is considered to be a classic back-arc basin. Back-arc basins may develop by active processes including retreat of the overriding plate or upwelling from the subducting slab. Alternatively, back-arc basins ...
U-Pb geochronology of the Late Cretaceous Eagle Ford Shale, Texas; defining chronostratigraphic boundaries and volcanic ash source
(2014-08)
The Eagle Ford Shale and equivalent Boquillas Formation (Late Cretaceous) contain abundant volcanic ash beds of varying thickness. These ash beds represent a unique facies that displays a range of sedimentary structures, ...
Provenance of the south Texas Paleocene-Eocene Wilcox Group, western Gulf of Mexico basin : insights from sandstone modal compositions and detrital zircon geochronology
(2009-08)
Sandstone modal compositions and detrital zircon U-Pb analysis of the Paleocene-Eocene Wilcox Group of the southern Gulf Coast of Texas indicate long-distance sediment transport primarily from volcanic and basement sources ...
Geochemistry and geochronology of meta-igneous rocks from the Tokat Massif, north-central Turkey
(2011-12)
Located in the Sakarya Zone of the eastern Pontides, the Tokat Massif is a Permian-Triassic metamorphic, volcanic, and sedimentary group of rocks cut by strands of the active strike-slip North Anatolian Shear Zone (NASZ). ...
Exhumation of the Lesser Himalaya of Northwest India : Zircon U-Pb and (U-Th)/He constraints and implications for the Neogene seawater evolution
(2016-08)
The kinematic and exhumational evolution of the Lesser Himalayan (LH) of Northwest India remains a topic of debate; the resolution of which may provide insight into the relationship between the weathering of chemically ...
Remote sensing, geochemistry, geochronology, and cathodoluminescence imaging of the Egrigoz, Koyunoba, and Alacam plutons, Northern Menderes Massif, Turkey
(2011-05)
The Egrigoz, Koyunoba, and Alacam plutons are located in the Northern Menderes Massif of western Turkey between the Simav normal fault to the south and the Izmir-Ankara-Erzincan suture to the north. Although much attention ...
Impact of meteoric fluid flow on the thermal evolution of Alpine exhumation : insights from the Gotthard Base Tunnel, Switzerland
(2016-05)
The Gotthard Base Tunnel provides a unique window into the subsurface of the Swiss Alps and into the complex thermal evolution of the Gotthard massif. The 58 km tunnel trends roughly N-S and provides an orogen perpendicular ...
Detrital zircon (U-Th)/(Pb-He) geo- and thermo-chronometric constraints on provenance and foreland basin evolution of the Ainsa Basin, south-central Pyrenees, Spain
(2016-08)
Synorogenic foreland basin fill of the south central Pyrenees preserves the eroded remnants of the early stages of Pyrenean fold-thrust belt evolution and topographic growth. Detailed isotopic provenance analysis allows ...
Provenance and geochronological insights into Late Cretaceous-Cenozoic foreland basin development in the Subandean Zone and Oriente Basin of Ecuador
(2018-07-27)
The evolution of sediment source regions in the Andes of Ecuador can be linked to Late Cretaceous-Cenozoic development of a subduction-related magmatic arc, retroarc fold-thrust belt, and flexural foreland basin. An ...
