ⓘ Sixiangkou meteorite, Sixiangkou, Gaogang District, Taizhou, Jiangsu, China

Polymorph of:

Albite, Kumdykolite

A hollandite-type high-pressure modification of (Na,Ca)AlSi₃O₈.
Compare also Liebermannite, the K analogue.

Compare UM2004-47-SiO:AlCaNa with which it may coexist in post-shock HP melt pockets.

Occurs in shock-melt veins in meteorites and impact rocks.
