Quality of the ground water in basalt of the Columbia River group, Washington, Oregon, and Idaho
Reuben Clair Newcomb
1972, Water Supply Paper 1999-N
The ground water within the 50,000-square-mile area of the layered basalt of the Columbia River Group is a generally uniform bicarbonate water having calcium and sodium in nearly equal amounts as the principal cations. water contains a relatively large amount of silica. The 525 chemical analyses indicate that the prevalent...

Water content of basalt erupted on the ocean floor
J.G. Moore
1970, Contributions to Mineralogy and Petrology (28) 272-279
Deep sea pillow basalts dredged from the ocean floor show that vesicularity changes with composition as well as with depth. Alkalic basalts are more vesicular than tholeiitic basalts erupted at the same depth. The vesicularity data, when related to experimentally determined solubility of water in basalt, indicate that K-poor oceanic...
