AFANASIEV S.V. et al. (2000) Dhofar 007 and Northwest Africa 011:
Two new eucrites of different types (MAPS 35-5, Suppl., 2000, A019):

Here we report data received by studying two new eucrites, Dhofar 007
from the Oman desert and NWA 011 from the Sahara desert. Based on
chemical, petrologic, and mineralogical analyses they are classified as
cumulate (Dhofar 007) and noncumulate (NWA 011).

Best regards,
