catalogue of western australian meteorite collections

that this is a mesosiderite occurrence or even that silicate overwhelmingly
predominated in the mass which formed the Da1garanga crater (p. 60).
Taking into account the predominance of octahedrite material in the recoveries
from Da1garanga, he prefers to regard this as an iron meteorite
(octahedrite) characterised by unevenly distributed silicate inclusions.
Stone, chondrite (?)
Two masses, total weight not recorded. Greyish lumps of material reported
by Nininger (1960) showing metallic specks and relic structure suggesting
chondrites but too weathered for exact identification.
This collection:
not represented.
Other collections: specimens recovered by H. H. Nininger held as far as
is known in his private collection (or at Arizona State University, Tempe,
Arizona). .
Analytical details, etc.: see note under Da1garanga stony-iron.
Shale-balls
Complex of siderites, siderolites (?), aerolites (?) and shale-balls regularly
distributed in relation to a small crater (see above), believed not to be an
explosion crater but a simple product of fragmentation.
This collection: W.A.M. No. 12190, two shale-balls, collected by H. H.
Nininger 10/10/1959 (55 and 38 g).

8. DALGETY DOWNS
(Synonym: Ashburton Downs)
Stone, olivine-hypersthene-chondrite
Find, 1941, six miles south of Da1gety Downs Station, Gascoyne District,
Western Australia. Latitude 25° 21' S., longitude 116° 11' E. Finder-
P. A. Hea1y. .
. -One mass, broken up on impact into many fragments, total weight 217· 7 kg
(480 lb.). This meteorite was first discovered by P. A. Hea1y in 1941 ;
a small piece has been kept in the collections of the Government Chemical
Laboratories, Perth, since 1941; a further sample 3·6 kg (c. 8 lb.) was
apparently passed to the Ka1goorlie School of Mines and held in their
collection from 1941 onwards. It appears that this specimen was erroneously
labelled Ashburton Downs. . It was thus listed by Nininger under
that name, and in fact al,8 kg piece has been represented for. some years
