A
number of small fragments of iron were found in and around a
crater 70 ft across and 11 ft deep, but only one of 40 g was
preserved in E.S. Simpson's collection, M.H.Hey, Cat. Met.,
1966, p.127. Described with partial analysis, E.S. Simpson,
Min. Mag., 1938, 25, p. 157. In 1960 a search around the crater
yielded 207 fragments with a total weight of 1.1 kg, the largest
weighing 57 g, of which about half were oxidised irons and half
mesosiderites. Within the crater 280 fragments, totaling about
20 lb were collected, all of which proved to be highly oxidized
mesosiderites..........
What
we are here looking at is a piece of the rare irons of which
some are displaying the kamacite-taenite crystallization even
without etching. The Melbourne Museum has got only a piece of
23 g!
This
is NOT the highly oxidized Mesosiderite
of which about 20 lb have been recovered from inside the crater,
these are the RARE Iron Individuals
and part-individuals collected outside the crater!
DALGARANGA
is the only known crater in the world created by a mesosideritic
meteorite impact approx. 270,000 years ago.
Surely
you don't need any more convincing that this is a real opportunity
to acquire one of the rarest Australian Meteorites.
What
are you waiting for?
