Type Occurrence of HarmuniteHide

General Appearance of Type Material:
Occurs in larnite pebbles of the pseudo-conglomerate, the cement of which consists of intensely altered larnite-bearing rocks. Srebrodolskite, magnesioferrite, and harmunite are intergrown forming black porous aggregates to the central part of the pebbles
Place of Conservation of Type Material:
St Petersburg University, Universytetskaya Naberezhnaya 7/9, 199034 St Petersburg, Russia, catalogue number 1/19518
Geological Setting of Type Material:
Hatrurim Complex of pyrometamorphic larnite rocks.
