33.78 grams. Pallasite, PMG-an
TKW 2.3 tons. Fall not observed. Found 1924, Northern Territory, Australia.
Graham writes:
In 1924 a meteoritic mass of 1,084 grams was found by Herbert Basedow on
Burt Plain, about 17 kilometres north of Alice Springs.
This mass was called Alice Springs, In July 1937, the main mass of 1,411.5
kilograms was recovered by Cecil Madigan at Huckitta (22°22'S, 135°46'E).
Over 900 kilograms of iron shale was also found. The Alice Springs meteorite
was then paired with the main mass and considered a transported fragment.
Today the location of the site where the main mass was found is on Arapunya
Cattle Station, which had been part of Huckitta Cattle Station but was
excised from it after the meteorite had been recovered?
It is a pallasite related to Main Group of pallasites. This pallasite is
severely weathered: almost all of the metal is highly oxidized and
transformed into hematite and magnetite, and olivine crystals are often
altered.Sometimes it is called an anomalous Main Group pallasite because,
compared to other Main Group pallasites, it has rather high Ge and Ga
contents, higher Pt, W, Ir, and lower Au content.
Main mass, Adelaide, South Australian Museum; 4.3 kg |

If that helps, over the years I have sold almost 2 kilos of Huckitta including a fragment of nearly 600g, and I have now a slice of 178g. I like Huckitta, it is such an odd meteorite.

If 1,411.5 kilograms was recovered and the main mass recorded is at Adelaide, South Australian Museum; 4.3 kg, I can't help but wonder where the other huge quantities are?
