MAP OF PAIRED METEORITES AT LUCERNE DRY LAKE, CALIFORNIA.
Between 1963 and 1999, 17 meteorite specimens (1.2-37.4 g), collectively called Lucerne Valley, have been found on Lucerne Dry Lake. Thirteen of the meteorite specimens from Lucerne Dry Lake were available for analysis (in 1999; in 2001 two more became available). Lucerne Dry Lake is ~3´ 6 km in size and is located in the southern Mojave Desert, ~17 km north of the San Bernardino Mountains.
Out of the 16 analyzed stones, there are 9 (nine) separate meteorites (falls).
This ratio is higher than comparable sized blow-outs in Roosevelt County, New Mexico, and the Nullarbor Plains of Australia.
The meteorites have retained the name Lucerne Valley (abbreviated LV); they are numbered in the order that they were found. The names have been approved by the Nomenclature Committee of the Meteoritical Society.

The three L6 chondrites (LV001/LV004+005 and LV011 and LV017) are distinguishable because they differ significantly in shock stage (S2, S4, and S3 respectively). The LL4 chondrite (LV002) is significantly less recrystallized (and much less oxidized) than the LL6 chondrite (LV015). The two H6 chondrites (LV003 and LV012) are distinguishable on the basis of their non-overlapping olivine compositional distributions (Fa18.0± 0.4 and 19.4± 0.3 mol%, respectively). The L5 chondrites (LV013/014/016) are significantly less recrystallized than either of the L6 chondrites; similarly, the H4 chondrite (LV006/008/009/010) is appreciably less recrystallized than the two H6 chondrites.
