ungrouped carbonaceous chondrite
subject			fact

ungrouped carbonaceous chondrite	is a kind of carbonaceous chondrite
carbonaceous chondrite	has relative abundance 8 % of meteorite falls
	has total mass of finds 2577 kg
	has number of finds 36
	has distinguishing feature elemental carbon
	has abundance rare relative to other chondrite types
chondrite	has petrologic type range which depends on degree of aqueous alteration and thermal metamorphism
	has part chondrule as a distinguishing feature -has URL: http://www.arachnaut.org/meteor/chondrules.html
	has homogeneity of olivine and low Ca pyroxene definition goes here
	has structural state of low Ca pyroxene definition goes here
	has part feldspar usually plagioclase tectosilicate
	has chondrule glass type
	has part metal maximum bulk in weight %
	has part mean Ni content of sulfides in weight %
	has part matrix fine grained disequilibrium mixture of silicates, oxides, metal, sulfides and organic constituents
	has part chondrule small sphere of about 1 mm diameter of formerly melted minerals
	has part carbon in weight %
	has part water in weight %
	has chondrule abundance in volume %
	has matrix abundance in volume %
	has refractory inclusion abundance in volume %
	has metal abundance in volume %
	has chondrule mean diameter millimeters
stony meteorite	has weather resistance low
	has fragmentation probability high because it is more friable than iron meteorite
	has ablative mass loss high because it is more friable than iron meteorite
undifferentiated meteorite	has peak temperature less than 950 degree Celsius during its entire history since solidification
	has parent body asteroid smaller than 100 km in diameter
	has age oldest and most primitive rock in solar system
meteorite	has fall date recorded by eyewitness or inferred from dating methods
	has fall location strewn fields, elongated footprints which depends on impact angle, airbursts, and impact velocity
	has fall coordinates in degrees, minutes and seconds of lattitude and longitude
	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 impact velocity when it hits the ground which is smaller than its velocity before it enters the atmosphere
	has impact angle
	has monetary value large if the fall was witnessed
	has name based on the locale, region, or nearby town in which the fall occurred
	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
	can shatter during impact phase
	can fragment during meteor phase
conglomerate	has sediment mechanism agglomeration of particles, many of which record individual, diverse histories
rock	has part mineral
	has texture
	has genesis
