Pre-Eruptive Magma Configurations and Petrogenetic Relationships of the Rattlesnake Tuff, Oregon–Insights From Spectacularly Banded High-Silica Rhyolite Pumices

Autor: Vanessa M. Swenton, Martin J. Streck

Publikováno v: Frontiers in Earth Science, Vol 10 (2022)

The 7.1 Ma Rattlesnake Tuff (RST) of eastern Oregon is a widespread and voluminous (>300 km3) ignimbrite composed of 99% crystal poor (≤1%) high-silica rhyolite (HSR) and

Columbia River Rhyolites: Age-Distribution Patterns and Their Implications for Arrival, Location, and Dispersion of Continental Flood Basalt Magmas in the Crust

Autor: Martin J. Streck, Vanessa M. Swenton, William McIntosh, Mark L. Ferns, Matt Heizler

Publikováno v: Geosciences, Vol 13, Iss 2, p 46 (2023)

Columbia River province magmatism is now known to include abundant and widespread rhyolite centers even though the view that the earliest rhyolites erupted from the McDermitt Caldera and other nearby volcanic fields along the Oregon–Nevada state bo

Picture Gorge Basalt: Internal stratigraphy, eruptive patterns, and its importance for understanding Columbia River Basalt Group magmatism

Autor: Emily B. Cahoon, Martin J. Streck, Anthony A.P. Koppers

Publikováno v: Geosphere. 19:406-430

The Picture Gorge Basalt (PGB) of the Columbia River Basalt Group (CRBG) has been previously thought to be limited in its eruptive volume (The geochemical identifiers used to differentiate PGB from other main-phase CRBG formations include lower TiO2

The Castle Rock and Ironside Mountain calderas, eastern Oregon, USA: Adjacent venting sites of two Dinner Creek Tuff units—the most widespread tuffs associated with Columbia River flood basalt volcanism

Autor: Matthew Cruz, Martin J. Streck

Publikováno v: GSA Bulletin. 134:2415-2435

The Dinner Creek Tuff is an important unit of mid-Miocene rhyolite volcanism contemporaneous to flood basalts of the Columbia River magmatic province. Field mapping along with analytical data of tuff samples identify two calderas, the Castle Rock and

Filling critical gaps in the space-time record of High Lava Plains and co-Columbia River Basalt Group rhyolite volcanism

Autor: Vanessa M. Swenton, Martin J. Streck, Daniel P. Miggins, William C. McIntosh

Publikováno v: GSA Bulletin.

Miocene rhyolitic volcanism of eastern Oregon, USA, can be divided into two main episodes. Mantle plume upwelling is thought to have generated Columbia River Basalt Group (CRBG) lavas and coeval >16.5−15 Ma silicic volcanism trending north−south

Reshuffling the Columbia River Basalt chronology—Picture Gorge Basalt, the earliest- and longest-erupting formation

Autor: Martin J. Streck, Emily B. Cahoon, Daniel P. Miggins, Anthony A. P. Koppers

Publikováno v: Geology. 48:348-352

The Columbia River Basalt Group (CRBG) is the world’s youngest continental flood basalt province, presumably sourced from the deep-seated plume that currently resides underneath Yellowstone National Park in the northwestern United States. The earli

Flood basalts, rhyolites, and subsequent volcanism of the Columbia River magmatic province in eastern Oregon, USA

Autor: Emily B. Cahoon†, Martin J. Streck†, Mark Ferns†

The Miocene Columbia River Basalt Group (CRBG) is the youngest and smallest continental flood basalt province on Earth. This flood basalt province is a succession of compositionally diverse volcanic rocks that record the passage of the Yellowstone pl

Volcanic glass as a proxy for Cenozoic elevation and climate in the Cascade Mountains, Oregon, USA

Publikováno v: Journal of Volcanology and Geothermal Research. 381:157-167

After deposition, volcanic glass hydrates with ambient water, recording the average hydrogen isotope ratio (δD or δ2H) of local meteoric water during the hydration period. Previous researchers have used ancient glass δD values to reconstruct paleo
