Igneous Processes

	Planetary Basalt Compositions Basalts from other worlds fall into the same tried and true categories as we find on Earth.		Textures of Extraterrestrial Basalts Basalts from other worlds have similar textures to those found on Earth.
	Extraterrestrial Cumulate Textures Igneous cumulates also form on other bodies, from asteroids to Mars.		Lunar Pyroclastic Eruptions Lunar fire fountaining sheds light on volcanic processes and volatile reservoirs inside the Moon.
	Exsolution in Iron Meteorites Exsolution of one metallic Fe-Ni mineral inside another allows measurement of cooling rates.		Exsolution in Lunar Pyroxene Pyroxene exsolution lamellae indicate cooling rates of lunar rocks.
	Mars High-Pressure Experiments Experiments at high temperature and pressure give clues to the composition of the interior of Mars.		Granite-Like Samples of Vesta Meteorites from asteroid 4 Vesta show that it contains patches of granite-like rock.
	Magma Ocean Crystallization—Experimental Approach Lab experiments help test ideas for the Moon's chemical composition and how its crust formed.
