Rex, which part/page/chapter of the CEM are you referring to?
On page 159, Fig.8.19, O.R. Norton says that Bencubbin, not
Gujba (!), is a mesosiderite from Western Australia, but he
also cautions: "This anomalous meteorite may be a new class
of mesosiderite". The first descriptions of Gujba in 1988 also
classified it as a mesosiderite [ISLAM M.R., OSTAFICZUK S.
(1988) The Gujba mesosiderite: its petrology, mineralogy and
impact (Annals of Borno 5, 110-124)] but in 2001, Bencubbin,
Gujba, HaH 237, QUE 94411, QUE 94627 and Weatherford were
assigned a new, separate group:

WEISBERG M.K. et al. (2001) A new metal-rich chondrite
grouplet - CB chondrites (MAPS 36-3, 2001, pp. 401-418).

Best regards and
a Happy New Year
to All of Us,
