Therefore, the knowledge of high-pressure behaviors of amblygonite helps understand the detailed crystal chemistry of such Li-bearing granites and can reflect the fundamental distinctions in the conditions of magma origin. However, comprehensive studies on the crystal structural evolution and physical ...
In many geologic environments involving the presence of fluid phase, external factors such as fluid composition, water/rock (W/R) ratios, dynamics of metasomatism including physicochemical conditions can control the major and trace element chemistry of gar- net [4]. The complex process of the ...
