On compositional variations among lunar anorthosites.

摘要: Ferroan anorthosite (FAN) is the most abundant 'pristine' highlands igneous rock in Apollo sample collection. The presence of substantial FAN lunar crust one argument used favor a global magma ocean on which crystallizing plagioclase could float. Information about composition proposed or whatever liquids might have been parental to sparse. As first step toward learning nature parent and processes by attained its compositional characteristics, attention given concentrations for number major trace elements whose behavior during magmatic somewhat understood. Serious difficulties are found with both Marcy interpreting incompatible element plagioclases whole rocks terms residues from liquids. A description presented these difficulties.
