1967, Contributions to Mineralogy and Petrology (15) 202-223
On eruption, the tholeiitic basalt lava of the prehistoric Makaopuhi lake contained nearly seven percent euhedral olivine phenocrysts of approximately Fa14 composition. In the center of the 225 foot vertical section of the lake, the lava became more than 90 percent solid at 1000° C after about 30 years. At the...
Ground-water research in the U.S.A.
C. L. McGuinness
1967, Earth-Science Reviews (3) 181-202
Ground-water reservoirs and the overlying unsaturated zone-collectively, the "subsurface"-have an enormous capacity to supply water to wells and useful plants, to store water to meet future needs for the same purposes, and, under suitable precautions, to accept wastes. This capacity can be exploited on a maximum scale, however, only on...
Mineral and chemical variations within an ash-flow sheet from Aso caldera, Southwestern Japan
P. W. Lipman
1967, Contributions to Mineralogy and Petrology (16) 300-327
Although products of individual volcanic eruptions, especially voluminous ash-flow eruptions, have been considered among the best available samples of natural magmas, detailed petrographic and chemical study indicates that bulk compositions of unaltered Pleistocene ash-flow tuffs from Aso caldera, Japan, deviate significantly from original magmatic compositions. The last major ash-flow sheet...
Borate mineral assemblages in the system Na2O-CaO-MgO-B2O3-H2O
C. L. Christ, A.H. Truesdell, Richard C. Erd
1967, Geochimica et Cosmochimica Acta (31) 313-337
The significant known hydrated borate mineral assemblages (principally of the western United States) in the system Na2O-CaO-MgO-B2O3-H2O are expressible in three ternary composition diagrams. Phase rule interpretation of the diagrams is consistent with observation, if the activity of H2O is generally considered to be determined by the geologic environment. The...
