Hello again,

In Met.Bull. 87, 2003 July, p. A196, the Dhofar 310 lunar meteorite is
described as "a fragmental regolith breccia", and, on page A30 of the
same issue, it is described as a "polymict breccia".

Reference:

DEMIDOVA S.I. et al. (2003) Lunar meteorite Dhofar 310: A polymict
breccia with deep-seated lunar crustal material (MAPS 38-7, 2003, A030).

Best wishes,

Bernd
