Orgueil
subject			fact

Orgueil	has image
	is an instance of meteorite fall
	is an instance of CI chondrite
	has name Orgueil
	has fall coordinates 43° 53' N., 1° 23' E.
	has fall date May 14, 1864 few minutes after 8:00 pm
	has mass 11 kg
meteorite fall	has value higher because the fall was witnessed
	has fall description what witnesses saw or what was recorded by instruments
	has weathering negligible due to quick recovery of meteorite before corrosion begins
CI chondrite	has prototype Ivuna meteorite
	has chondrule abundance less than 1 % by volume
	has matrix abundance greater than 99 % by volume
	has refractory inclusion abundance less than 1 % by volume
	has metal abundance 0 % by volume
	has chondrule mean diameter no chondrules
	has tenacity friable
	has volatile content high
meteorite	has fall location strewn fields, elongated footprints which depends on impact angle, airbursts, and impact velocity
	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
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
type 1 chondrite	has petrologic type 1
	has degree of aqueous alteration strong
	has part matrix all fine-grained, opaque
	has part chondrule no chondrules
	has part carbon 3 to 5 % by weight
	has part water 18 to 22 % by weight
rock	has part mineral
	has texture
	has genesis
chondrite	has petrologic type range which depends on degree of aqueous alteration and thermal metamorphism
	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 %
water altered chondrite	has metamorphism mechanism aqueous altermation
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
altered chondrite	has degree of secondary processing providing insight into geological evolution of parent asteroid
conglomerate	has sediment mechanism agglomeration of particles, many of which record individual, diverse histories
