Required Geological Setting

Accretionary complexes


Aggregates of Na-dominant minerals formed by the reaction of gabbro and/or basalt blocks with reductive, hyperalkaline fluids produced by serpentinization. The fluid produced by serpentinization is reductive, hyperalkaline, and Ca-rich. This fluid becomes Na and Ti-rich by consuming Ca in the course of rodingitization reactions with gabbro and/or basalt blocks. Na-dominant minerals such as Na-amphiboles, albite, and jadeite deposit from this reductive, hyperalkaline and Na and Ti-rich fluid. As these minerals do not contain Sr, Sr-dominant minerals may be observed.
