superliquidus chondrule
subject			fact

superliquidus chondrule	is a kind of chondrule
	has origin droplet melted beyond superliquidus temperatures, eliminating most viable nuclei
	has nucleation mechanism impinging fine-grained dust
chondrule	has diameter usually less than 1 mm but can range from 0.1 to 10 millimeters
	has relative volume 80 % of volume of ordinary and enstatite chondrite and greater than 15 % of most other chondrite groups
	has composition glass
	has texture
	has abundance most abundant part of chondrite meteorite

Kinds of superliquidus chondrule :

• barred olivine chondrule (5 facts) (BO chondrule) - chondrule with one or more sets of strongly elongated parallel prismatic olivine crystals
• radial pyroxene chondrule (5 facts) (RP chondrule) - chondrule with thin needles of pyroxene radiating from a single point on the edge of the chondrule
