Thermal instabilities and the formation of lunar maria

The Moon, 1973
A model is discussed for a possible type of thermal instability in the outer layers of the Moon. An estimate is made for the temperature differential driving the instability. It is suggested that such an instability may have been involved in the formation of the lunar maria.

Galileo imaging observations of lunar maria and related deposits [PDF]

open access: yesJournal of Geophysical Research: Planets, 1993
The Galileo spacecraft imaged parts of the western limb and far side of the Moon in December 1990. Ratios of 0.41/0.56 μm filter images from the Solid State Imaging (SSI) experiment provided information on the titanium content of mare deposits; ratios of the 0.76/0.99 μm images indicated 1 μm absorptions associated with Fe2+ in mafic minerals.

Volcanic features of the nearside equatorial lunar maria

open access: yesJournal of the Geological Society, 1976
A map is presented of the distribution of volcanic features in the lunar maria between longitudes 50°E. and 100°W, and latitudes 50°N. and S. Flood basaltic flows predominate, and where individual flow units can be identified they may be hundreds of kilometres long.

The Distribution and Ages of Regional Lithologies in the Lunar Maria [PDF]

open access: yes, 1970
A research program was designed (1) to map regional lithological units of the lunar surface based on measurements of spatial variations in spectral reflectance, and, (2) to establish the sequence of the formation of such lithological units from measurements of the accumulated affects of impacting bodies.

Dimensional Correlation of Lunar Maria and Terrestrial Ocean Basins

Nature, 1962
IN a previous paper1 I have shown that the correlation of diameter versus depth for lunar craters of different apparent ages can be understood in terms of the former presence of a lunar hydrosphere lasting some milliards of years, affecting the relative dimensions at crater formation. Furthermore, this correlation of dimensions included the lunar maria,

Internal origin for lunar rilled craters and the maria?

Nature, 1974
THE origin of lunar craters has been attributed to both volcanism1–3 and/or impact4–6, although since the return of the Apollo 11 volcanic rocks opinion has favoured an endogenic origin for a greater part of the lunar morphology than was previously accepted7.

A New Method of Determining the Depth of the Lava in Lunar Maria

Publications of the Astronomical Society of the Pacific, 1970
It has been generally recognized that the flows in Mare Nubium and southern Oceanus Procellarum are relatively shallow. Much of Oceanus Procellarum and the central craters of the circular maria are filled with thicker lavas (Baldwin 1949). There are two lines of reasoning applied here.
