EUGENE, Ore. - July 17, 2020 - Uplifting of Columbia River basalts has allowed University of Oregon researchers to better understand of how magma 14-16 million years ago shaped the region and why ...

The formation, called Columbia River basalt, dates back to a mind-bendingly huge lava flow 15 to 16 million years ago. The volcanic basalt underlies much of the Columbia River basin.

Basalt rocks line the Columbia River in southeastern Washington. Pacific Northwest National Lab said storing CO2 in basalt will be one tool to sequester carbon. But, they want to be respectful of ...

Flood basalts appear to form during the initiation of hotspot magmatism. The Columbia River basalts (CRB) represent the largest volume of flood basalts associated with the Yellowstone hotspot ...
