Vermillion
subject			fact

Vermillion	has image
	is an instance of pyroxene grouplet pallasite
	is an instance of meteorite find
	has name Vermillion
	has find date May, 1991
	has fall coordinates 39° 44.18' N., 96° 21.68' W.
	has fall location grain field in Marshall County, Kansas
	has mass 34.36 kg
	has olivine content 14 % by volume
	has olivine grain shape rounded to subrounded 1.5 cm
	has olivine grain size 1.5 cm
	has pyroxene content 0.7 % by volume (orthopyroxene)
	has chromite content 0.2 % by volume
pyroxene grouplet pallasite	has distinguishing feature large mm sized pyroxene crystals poikilitically containing small olivine grains
meteorite find	has value lower because the fall was not witnessed
	has weathering can be severe due to long exposure time to environmental corrosion agents
pallasite	has composition metallic iron plus olivine; core/mantle boundary samples
	has letter designation PAL
	has phosphate content 1 % or less by volume
	has olivine crystal distribution from homogeneous to heterogeneous
	has formation cooling rate 2.5 to 4 degrees C per million years
	parent body radius 78 to 97 kilometers
	has total mass of finds 7207 kg
	has number of finds 33
meteorite	has fall date recorded by eyewitness or inferred from dating methods
	has fall map which appears as an elongated footprint which depends on impact angle, airbursts, and impact velocity
	can have crater image
	has original mass which can over an order of magnitude greater than total mass of fragment(s) collected at the impact site
	has composition often minerals not found on Earth
	has relative abundance
	has total mass of finds 485755 kg
	has number of finds 1691
	has impact velocity when it hits the ground which is smaller than its velocity before it enters the atmosphere
	has impact angle
	has weather resistance which depends on its composition
	has monetary value large if the fall was witnessed
	often produce power outages and failures in electrical equipment due to EMP (electromagnetic pulse)
	can be associated with crater
	has origin meteoroid from interplanetary space or fragment dislodged from another planet, moon or planetesimal
	vaporizes completely if size is between 3 micrometers and 3 millimeters
	can survive fall if size is larger than 3 mm and velocity is less than 24 km per second
	can survive fall if it fragments because smaller pieces with less mass are more easily slowed by the atmosphere
	has ablative mass loss depending on composition, more friable stony meteoroids loses more mass than iron meteoroid
	has ablative mass loss directly proportional to initial velocity
	can shatter during impact phase
	can fragment during meteor phase
	has fragmentation probability during meteor phase which depends on composition
rock	has part mineral
	has texture
	has genesis
metal-rich meteorite	has metal content higher than that of average solar system material
	has nickel content always greater than 4 %
igneous rock	has solidification mechanism
	has solidification timescale
