Abstract

Chemical and physical data are given for five samples of rock-forming apatite from diverse geologic environments in Nevada and Colorado.  Four of these apatites contain rare-earth assemblages in which the cerium group is well represented but the yttrium group predominates.  The fifth apatite contains a highly fractionated assemblage of the lighter (cerium group) rare earths similar to the assemblage typical of alkulic rocks.
