Lunar nomenclature: A dissenting note
D.W.G. Arthur
1976, Icarus (27) 571-573
This note reviews the nature of the traditional (Mädler) lunar nomenclature and the recent developments based on the use of more than 2000 named provinces. It appears that the new nomenclature is less efficient than the old in many cases and may lead to an impossible publication situation. The unnecessary...

Alvin John Feulner, Chester Zenone, K. M. Reed
1976, Open-File Report 76-82
Sheyma Island, Alaska, was occupied as a military base in 1942. Since that time, potable water has been supplied by streams, lakes, wells, and in the late 1950's, a gallery system. The island is a low-lying, wave-cut platform composed of pyroclastic and volcanic rocks with some intrusives. Bedrock is overlain...
Disharmony of the spheres: Recent trends in planetary surface nomenclature
R.J. Pike
1976, Icarus (27) 577-583
Inadvisable departures from tradition in naming newly mapped features on Mars, Mercury, and the Moon have been implemented and proposed since 1970. Functional need for place names also has become confused with cartographic convenience. Much of the resulting new nomenclature is neither unique, efficient, nor imaginative. The longstanding classical orientation...

Mixing of carbonate waters
T.M.L. Wigley, Niel Plummer
1976, Geochimica et Cosmochimica Acta (40) 989-995
When mineral solutions of different compositions are mixed, the molalities and activities of individual ions in the mixture are often non-linear functions of their end-member values. This non-linearity is particularly significant in determining mineral saturation levels. Mixtures of saturated solutions may be either...
