Chlorine and fluorine abundances in ultramafic rocks
Geochimica et Cosmochimica Acta, 1968Abstract A total of 55 ultramafic rocks of various modes of occurrence has been analysed for chlorine and fluorine by a rapid spectrophotometric method. The different modes of occurrence seem to have different abundance levels of Cl and F, but this may be due to secondary effects.

Peridotites and other ultramafic rocks
Geology TodayPeridotites are a group within the category of ultramafic rocks. These are usually dark‐coloured rocks rich in magnesium, poor in silica and lacking feldspars. Earth's mantle, which makes up 83 percent by volume and 67 percent by weight of the planet, consists largely of peridotite, which, although relatively sparse at the surface, therefore, is Earth ...

Carbonated ultramafic igneous rocks in Jezero crater, Mars
ScienceThe Perseverance rover landed in Jezero crater on Mars, which once contained a lake of liquid water. We report the rock properties encountered by Perseverance during a 10-kilometer traverse extending over 400 meters in elevation, from beneath Jezero’s western sedimentary fan to the upper crater rim.
