WebWhitlockite is the predominant phosphate mineral in meteorites. Small variations in its composition can be correlated with other compositional features that vary from one class of meteorites to another. Chlorapatite is found in meteorites to the exclusion of fluorapatite, which is the common apatite found in igneous rocks.
