Introduction: Six new chondrites have been recovered by Richard and Roland Pélisson during a 1998 systematic search for meteorites in the Dar al Gani and Hamada al Hamra regions. Over the past several years their efforts have resulted in the recovery and documentation of over 200 meteorites, most of which are still in various stages of research. Significant among these six finds are an LL4 (DaG 860) and an H3 (DaG 862). In addition an accurate location map has been constructed which positions all of the reported finds from Dar al Gani.

Results: In appearance DaG 862 resembles the L3.5 chondrite Ragland, New Mexico especially in the number of chondrules seen in a cut section. Mineralogically, olivine compositions have a wide range from Fa 0.33 to 32.29, as do the pyroxenes that range from Fs 1.09 to 32.21.


Science needs good documentation.

All the meteorites discovered during our expeditions have been documented in great detail, with photos of the principal mass, analysis results, and images of cuttings showing their internal structure. All this information is stored on CD-ROM.
