A
shower of stones fell approx. five miles East of Wiluna township,
after a fireball and a sonic boom were observed.
There
were estimated about 500 - 1000 stones distributed over an NW
to SE elongated ellipse of 4
x 2 miles,
weighing from 10 kg - 2.2 g.
Chemical
Bulk Analysis of the WILUNA:
SiO2=39.59%,
TiO2=0.10%, Al2O3=2.65%, Cr2O3=0.63%, FeO=9.5%, MnO=0.27%, MgO=24.06%,
CaO=1.88%, Na2)=0.95%, K2O=0.10%, P2O5=0.16%, H2O+=0.08%, Fe
m=14.73%, Ni=1.58%, Co=0.081%, FeS=3.39%.
Radiometric
dating of the meteorite itself estimates an age of about 4.5
billion years, suggesting it was formed at the very beginning
of the Solar System, and which makes it among the oldest material
known to exist ( the oldest rocks on Earth being only half its
age!).
We
hope you will enjoy owning this unique piece of our Solar System,
your own Space Traveler, from way out there.
Is
this really something special? You bet!
A Meteorite of an observed
W.A. Fall,
