Crystal subhedral

A record of morphology classes for each pyrite occurrence was kept during petrographic analyses. Monocrystalline pyrite includes euhedral and subhedral pyrite crystals. This morphology class is always more prevalent than framboidal pyrite except at the top of core 1 and the bottom of core 3. 

Kakangari matrix contains mostly euhedral to subhedral crystals with grain sizes of 200 nm to... 

Late ferroan dolomite forms large cloudy crystals riddled with inclusions (Fig. 15A), patches of sparry dolomite (Fig. 15B) and large individual euhedral to subhedral rhombs (Fig. 15D) up to... 

Photograph 7-21 Blue, subhedral alite crystals with very narrow belite fringe (almost the only belite in the clinker) and matrix of gray aluminate and dull ferrite. Average alite size is approximately 26 pm. Coal-fired, dry-process kiln, 550 tons/day. (S A6641)...
