Ordinary chondrite, xenolithic (LL6; S3)
Fell, 14 July 1860; ≥150 kg

After detonations and a fireball several stones fell, the largest estimated to be ~ 150 kg. However, only 32 kg were recovered. While total iron (~18 wt%) along with olivine (Fa~28) and orthopyroxene (Fs23 -'hypersthene') composition indicate an overall LL chondrite, several xenoliths are present as well. Olivine in matrix and occasionally in often fractured chondrules is abundant with orthopyroxene, plagioclase-and-feldspathic glass, troilite, and Fe-Ni metal accounting for most of the remaining mass. Accessory minerals include chromite, minor opaques, and merrillite [clearly observed by Tschermak and later identified as a new mineral by Merrill (1915)]. A cosmic ray exposure age of 10.4 Ma has been reported.

The LL ordinary chondrites (relatively very low in bulk iron) represent ~ 10% of all meteorite falls. At the beginning of 2017, Dhurmsala was the 6th most massive of the 43 witnessed falls classified exactly as an 'LL6' chondrite.
