Science, 1982
Between 17 million and 6 million years ago, 200,000 square kilometers of the American Northwest were flooded by basaltic lava that erupted through fissures in the crust up to 150 kilometers long. Larger individual eruptions covered over a third of the Columbia Plateau in a few days. The lavas represent partial melts of the earth's mantle that were only

Rare Earth Elements in Abyssal Basalts and Plateau Basalts
Nature Physical Science, 1971IT is current practice to compare the abundances of the rare Earth elements (REE) in various rocks as well as in lunar materials with those in chondrites when exploring their origins. It should be emphasized that Masuda–Coryell plotting (Masuda1, 1962; Coryell et al.2, 1963) played an important part in studies of REE abundances in terrestrial and ...
