Tieschitz
subject			fact

Tieschitz	has image
	is an instance of L3 chondrite
	is an instance of meteorite fall
	has petrologic subtype 3.6
	has name Tieschitz
	has fall date 1:45 pm July 15, 1878
	has fall coordinates 49° 36' N., 17° 7' E.
	has fall location Prostejov, Jihomoravsky, Czechoslovakia
	has mass 27.4 kg
L3 chondrite	has total mass of finds 131 kg
	has number of finds 10
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
L chondrite	has synonym hypersthene chondrite
	has chondrule abundance 60 to 80 % by volume
	has matrix abundance 10 to 15 % by volume
	has refractory inclusion abundance 0.1 to 1 % by volume
	has metal abundance 5 % by volume
	has chondrule mean diameter 0.7 millimeters
	has total iron content low
	has metal iron content 5 to 10 %
	has iron metal and iron sulfide 50 % of total iron
type 3 chondrite	has petrologic type 3
	has degree of aqueous alteration none
	has degree of thermal metamorphism none
	has olivine and low Ca pyroxene homogeneity greater than 5 % deviations
	has structural state of low Ca pyroxene predominantly monoclinic
	has chondrule glass type clear, isotropic, variable abundance
	has part feldspar minor primary grains only
	has part maximum bulk Ni in metal greater than 20 % by weight, kamacite and taenite in exsolution relationship
	has part sulfide Ni content less than 0.5 % by weight
	has part matrix clastic and minor opaque
	has part chondrule chondrules very sharply defined
	has part carbon 0.2 to 1 % by weight
	has part water 0.3 to 3 % by weight
meteorite	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 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
ordinary chondrite	has abundance most common chondrite observed from falls
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 part metal maximum bulk in weight %
	has part mean Ni content of sulfides in weight %
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
conglomerate	has sediment mechanism agglomeration of particles, many of which record individual, diverse histories
