40Ar/39Ar Geochronology of Magmatic-Steam Alunite from Alunite Ridge and Deer Trail Mountain, Marysvale Volcanic Field, Utah: Timing and Duration of Miocene Hydrothermal Activity Associated with Concealed Intrusions

Autor: Cameron M. Mercer, Michael A. Cosca, Albert H. Hofstra, Wayne R. Premo, Robert O. Rye, Gary P. Landis

Publikováno v: Minerals; Volume 12; Issue 12; Pages: 1533

Porphyry and epithermal deposits are important sources of base and precious metals. Most actively mined deposits have been exhumed such that ore bodies are relatively close to the surface and are therefore locatable and economic to extract. Identifyi

Age and mantle sources of Quaternary basalts associated with 'leaky' transform faults of the migrating Anatolia-Arabia-Africa triple junction

Autor: Christian Teyssier, Michael A. Cosca, Jonathan R. Delph, Wayne R. Premo, Mary R. Reid, Bora Rojay, Gonca Gençalioğlu Kuscu, Donna L. Whitney, Janne Blichert-Toft

The Anatolia (Eurasia), Arabia, and Africa tectonic plates intersect in southeast Turkey, near the Gulf of İskenderun, forming a tectonically active and unstable triple junction (the A3 triple junction). The plate boundaries are marked by broad zone

Combined radiogenic (87Sr/86Sr, 234U/238U) and stable (δ88Sr) isotope systematics as tracers of anthropogenic groundwater contamination within the Williston BasinUSA

Autor: Leonid A. Neymark, Poul Emsbo, Wayne R. Premo

Publikováno v: Applied Geochemistry. 96:11-23

The Williston Basin has produced oil and gas from conventional structural and stratigraphic traps for more than 60 years. The advent of horizontal drilling and hydraulic fracturing of shale in the Devonian-Mississippian Bakken Formation has increased

U-Pb ages and geochemistry of zircon from Proterozoic plutons of the Sawatch and Mosquito ranges, Colorado, U.S.A.: Implications for crustal growth of the central Colorado province

Autor: Joseph L. Wooden, Wayne R. Premo, Richard J. Moscati, Ed DeWitt

Publikováno v: Rocky Mountain Geology. 52:17-106

A broad study of zircons from plutonic rocks of the Sawatch and Mosquito ranges of west-central Colorado (U.S.A.) was undertaken to significantly refine the magmatic chronology and chemistry of this under-studied region of the Colorado province. This

Identification of the late Homerian Mulde Excursion at the base of the Salina Group (Michigan Basin, USA)

Autor: Patrick I. McLaughlin, Nicholas B. Sullivan, Poul Emsbo, Wayne R. Premo, James E. Barrick

Publikováno v: Lethaia. 49:591-603

Constraining the age of strata is a fundamental source of uncertainty in the study of sedimentary rocks, particularly in restricted basins that generally lack index fossils. An illustrative example of this is the evaporite-bearing Salina Group in the

Refining 2 km of Ordovician chronostratigraphy beneath Anticosti Island utilizing integrated chemostratigraphy

Autor: Esther Asselin, Aicha Achab, M. Matthew Emmons, John F. Riva, Carlton E. Brett, Patrick I. McLaughlin, Wayne R. Premo, Alyssa M. Bancroft, Poul Emsbo, André Desrochers, Leonid A. Neymark

Publikováno v: Canadian Journal of Earth Sciences. 53:865-874

New high-resolution chemostratigraphy, in combination with updated biostratigraphy, refines the chronostratigraphic resolution of the nearly 2 km thick Ordovician section below Anticosti Island. A total of 1414 horizons, spaced at 1.0–1.5 m interva
