EETA 79001
subject			fact

EETA 79001	is an instance of depleted basalt shergottite
	is an instance of Antarctic meteorite
	has name EETA 79001
	has fall location Elephant Moraine, Antarctica
	has find date 1979
	has identification date 1980
	has mass 7.90 kg
	has curatorial location MWG (JSC), SI
	has SiO2 content 48.5 % by mass
	has TiO2 content 0.63 % by mass
	has Al2O3 content 5.69 % by mass
	has Cr2O3 content 0.61 % by mass
	has FeO content 18.6 % by mass
	has MnO content 0.48 % by mass
	has MgO content 16.4 % by mass
	has CaO content 7.22 % by mass
	has Na2O content 0.84 % by mass
	has K2O content 0.04 % by mass
	has P2O5 content 0.60 % by mass
	has sulfur content 0.20 % by mass
shergottite	has letter designation AEUC
depleted basalt	has composition depleted by gravitational separation
meteorite	has fall date recorded by eyewitness or inferred from dating methods
	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 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
SNC meteorite	is an acronym for Shergottite, Nakhilite, Chassignite
volcanic rock	has solidification mechanism extrusion onto the surface of the planet or asteroid via a volcanic eruption
	has solidification timescale very rapid
gravitationally separated rock	has property formed by separation of molten rock in a gravity field
rock	has part mineral
	has texture
	has genesis
achondrite	has distinguishing feature no chondrules
