A geologic investigation of Death Valley California
Death Valley, California has a rich geologic history and a landscape shaped by diverse tectonic and volcanic activities. Modern-day Death Valley is the product of extensional tectonism, rhyolitic volcanism, and basin ...
Geologic evolution of the Argentinian Andes
Over the past 2.1 Ga the western margin of South America has been subjected to a series of distinct orogenic events. Ongoing field research, including construction of detailed cross sections, will further define tectonic ...
Modeling Middle Devonian deposition in the Selwyn Basin, Northern Yukon.
A Ni-Mo-PGE sulfide deposit (NiMo) in norteastern Yukon occurs at the boundary between Ordovician-Early Devonian Road River and Middle Devonian Earn Group. This research investigated multiple genetic models for basin-wide ...
Geological Analysis of the Northern Margin of the Boulder Batholith : an EdMap Project.
Southwest Montana experienced large-scale magmatism and regional contraction during the Late Cretaceous. Understanding the genetic linkages between these geologic processes is important for understanding the causes of ...
Geologic Exploration of the Northern Central American Arc : a Transect from the Guatemalan Highland into the Back Arc Rainforests.
Guatemala is composed of the Maya and Chortis Blocks, which consist of Proterozoic and Paleozoic basement terranes that have been intruded by subduction-related magmas since the Mesozoic. The modern Central American Arc ...
Detrital Zircon Evidence Requires Revision of Belt Stratigraphy in Southwest Montana.
The Belt Supergroup was originally named for widespread exposures of thin-bedded red clastic strata in the Big Belt Mountains in southwestern Montana. Subsequent studies extended the geographic extent and thickness of the ...
