Uplifting of Columbia River basalts opens window on how region was sculpted University of Oregon via ScienceDaily 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 greenhouse gases released during a series of volcanic eruptions did not trigger a global extinction event. The insights, published in Scientific Reports, were drawn from analyses of oxygen and hydrogen isotopes in crustal material, a mix of magma and original rocks, that is now exposed by geological uplifting and erosion.
