Lunar volcanic deposits are dominated by areally extensive mare units occurring in regionally low areas predominantly on the lunar near side. Data obtained from lunar orbit and earth-based observations have been used to extend the detailed characterizations derived from Apollo and Luna sample return missions to other parts of the moon. Mare volcanism occurred over a period of about 1.3 billion years (b.y.), from about 3.8 to about 2.5 b.y. ago, although the absolute age of the youngest flows is… 

Beginning and end of lunar mare volcanism

Mare volcanism on the Moon is commonly attributed to an important but relatively short-lived epoch of internal heating after 3,900 Myr BP but before about 2,500 Myr BP (refs 1, 2). Although some

Ages and stratigraphy of lunar mare basalts: A synthesis

The chronology of lunar volcanism is based on radiometric ages determined from Apollo and Luna landing site samples, regional stratigraphic relationships, and crater degradation and size-frequency

Large shield volcanoes on the Moon

The volcanic style of the Moon has long been understood to consist almost exclusively of flood basalts erupted from fissures along with minor pyroclastic activity; large central vent shield volcanoes

Volcanic geology of Tyrrhena Patera, Mars

Tyrrhena Patera is a large, low-relief volcano located in the southern cratered highlands of Mars on a proposed ring fracture of the Hellas basin. The volcano is composed of four or possibly five

Mare volcanism: Reinterpretation based on Kaguya Lunar Radar Sounder data

The Lunar Radar Sounder (LRS) onboard Kaguya (SELENE) detected widespread horizontal reflectors under some nearside maria. Previous studies estimated that the depths of the subsurface reflectors were

The paleoinclination of the ancient lunar magnetic field from an Apollo 17 basalt

Paleomagnetic studies of Apollo samples indicate that the Moon generated a core dynamo lasting for at least 2 billion years. However, the geometry of the lunar magnetic field is still largely



Lunar basin formation and highland stratigraphy

Multiring impact basins, formed after solidification of the lunar crust, account for most or all premare regional deposits and structures expressed in the lunar landscape and for major topographic

Lunar igneous rocks and the nature of the lunar interior

Lunar igneous rocks, properly interpreted, can give useful information about mineral assemblages and mineral chemistry as a function of depth in the lunar interior. Though intensely brecciated, terra

Ages of the lunar nearside light plains and maria

An extension of a previous work on relative age mapping for the lunar nearside is presented. The ages were determined from Apollo (Hasselblad, metric, and panoramic) and Lunar Orbiter photographs;

Mare volcanism and lunar crustal structure

It is pointed out that the concept of hydrostatic head, the height to which a fluid at a given pressure will rise in a gravitational field, can be usefully applied to magmatic liquids and to a number

Descartes region: Evidence for Copernican‐Age volcanism

A model that suggests that the high-albedo central region of the Descartes Formation was formed by Copernican-age volcanism was developed from Orbiter photography, Apollo 12 multispectral

Identification, distribution and significance of lunar volcanic domes

Over 300 previously unrecognized volcanic domes were identified on Lunar Orbiter photographs using the following criteria: (1) the recognition of land forms on the Moon similar in morphology to

Xenoliths in Maars and Diatremes with Inferences for the

Maar-type volcanoes and their eroded remnants, diatremes, are believed to be terrestrial counterparts of crater chain rilles and possibly of the dark halo craters observed in lunar and Martian

Flows of impact melt at lunar craters

Lavalike materials that were emplaced in a fluid state occur in and around lunar impact craters whose diameters range from 3 km to more than 200 km and whose ages span a time interval of at least 3.5
