Name:
Named after Takashi Yoshioka (1935-1983), mineralogist, Nihon Cement Company (Japan).
Compare Unnamed (Ca-Al-(Si) oxide I), Unnamed (Ca-Al-(Si) oxide II), Unnamed (Ca-Al-(Si) oxide III), Unnamed (Ca-Al-(Si) oxide IV) and Unnamed (Ca-Al-Si oxide) - terrestrial phases also connected with high pressures.
Present as shocked crystal fragments and within devitrifed glasses in lunar regolith breccia. The glass may be due to shock melting of anorthite on ancient lunar highlands.
Metastable.
