Imilac is classified as a stony–iron pallasite. Imilac specimens are highly prized by meteorite collectors due to its high concentration of beautiful olivine grains.
Numerous masses were found in a valley to the SW of Imilac. The total weight of the Imilac fall is estimated to be around 1000 kg. The primary strewn field is long about 8 km.[2]
Due to weathering, intact olivine grains are present only on large specimens (over 1 kg). Smaller samples contains darker alterated olivine cristals. On the market there are also a lot of very small (few grams) Imilac individuals called metal skeletons: they are severely weathered and lack olivine grains.
