The majority of Moon rocks contain minor amounts ([less than or equal to] 3%) of REE-bearing minerals: apatite ([Ca.sub.5](P[O.sub.4])(F,Cl)) merrillite (([Ca.sub.3])[(P[O.sub.4).sub.2]) and/or monazite ((Ce,La,Nd,Th)(P[O.sub.4])(Si[O.sub.4])).

Scientists at the University of Nevada, Las Vegas analyzed a mineral called merrillite found in Martian meteorites, according to a study (http://https://www.eurekalert.org/pub_releases/2017-03/dbnl-nef030317.php) published Monday in the journal Nature Communications .
By performing shock and compression experiments on a synthetic version of whitlockite, scientists found that the mineral became "dehydrated" from the shocks, effectively forming merrillite.
Instead of having fluorapatite, Mars has chlorapatite, where chlorine takes place of the fluorine component; it also has a phosphate-bearing mineral called merrillite, not found on Earth.
