Abstract

This thesis is composed of two parts (six chapters). The first part (first two
chapters) details a petrologic study of a suite of spinel ± garnet lherzolite xenoliths from
Ming-xi, Fu-jian Province, southeastern China. The second part deals with experimental
studies of systematic variations in compositions of lherzolite minerals with pressure and
temperature in (complex) model lherzolite systems ...
In conclusion, this study emphasizes systematic changes exhibited in mineral and
whole-rock compositions and the causes of these changes, and demonstrates some
possible ways of predicting these changes. Mantle processes are complicated, but in
recognizing the three major processes (partial melting, recrystallization, and
metasomatism), which are the main causes of the changes in mineral and whole-rock
compositions, and in scrutinizing them, they can be comprehended. This idea is
manifested in, among others, the detailed modelling of the partial melting process
experienced by the Ming-xi lherzolite suite, the development of various mineral
barometers and thermometers, and the realization of the two important types of subsolidus
mineral reactions in the lherzolite system.
