radial pyroxene chondrule (RP chondrule)
subject			fact

radial pyroxene chondrule	is a kind of superliquidus chondrule
	is a kind of ferromagnesian chondrule
	has definition chondrule with thin needles of pyroxene radiating from a single point on the edge of the chondrule
	has texture thin needles of pyroxene radiating from a single point on the edge of the chondrule
	has acronym RP chondrule
superliquidus chondrule	has origin droplet melted beyond superliquidus temperatures, eliminating most viable nuclei
	has nucleation mechanism impinging fine-grained dust
ferromagnesian chondrule	has composition ferromagnesian minerals
	has abundance most chondrules are ferromagnesian
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
