Lithologic Mapping of HED Terrains on Vesta using Dawn Framing Camera Color Data

open access: yes, 2013
The surface composition of Vesta, the most massive intact basaltic object in the asteroid belt, is interesting because it provides us with an insight into magmatic differentiation of planetesimals that eventually coalesced to form the terrestrial planets.

Research in volcanic geology, petrology and planetary science at MIT, 1969 to 1974 [PDF]

open access: yes
The behavior of volcanoes was studied by geologic mapping, petrologic investigations of lava and xenoliths, physical measurements, and theoretical modelling. Field observations were conducted in Alaska (Nunivak Island), Iceland, Hawaii (Mauna Kea), Italy

Toward quantification of strain-related mosaicity in shocked lunar and terrestrial plagioclase by in situ micro-X-ray diffraction [PDF]

open access: yes, 2015
Studies of shock metamorphism of feldspar typically rely on qualitative petrographic observations, which, while providing invaluable information, can be difficult to interpret.

Mineralogic and petrologic studies of meteorites and lunar samples [PDF]

open access: yes
During a 13 year period beginning in 1971, the Extraterrestrial Petrology Group examined lunar soils from all 6 Apollo missions and those returned by the Soviet Luna 16, Luna 20, and Luna 24 missions.

Workshop on Moon in Transition: Apollo 14, KREEP, and Evolved Lunar Rocks [PDF]

open access: yes
Lunar rocks provide material for analyzing lunar history and now new evaluation procedures are available for discovering new information from the Fra Mauro highlands rocks, which are different from any other lunar samples.

Experimental petrology and origin of Fra Mauro rocks and soil [PDF]

open access: yes
Melting experiments over the pressure range 0 to 20 kilobars were conducted on Apollo 14 igneous rocks 14310 and 14072 and on comprehensive fines 14259.

Apollo 14: Some geochemical aspects [PDF]

open access: yes
Chemical analyses were obtained for five samples of Apollo 14 regolith fines, three 14230 core samples, soil clod 14049, breccias 14305 and 14319, 14310 basalt, and some separated phases.
