Imilac is a pallasite meteorite found in the Atacama Desert of Northern Chile in 1822.

Classification[edit]

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.

Strewn field[edit]

Numerous masses were found in a valley to the SW of Imilac. The total weight of the Imilac fall is estimated to be around 1,000 kilograms (2,200 lb). The primary strewn field is long about 8 kilometres (5.0 mi).[2]

Specimens[edit]

Individual

Due to weathering, intact olivine grains are present only on large specimens (over 1 kilogram (2.2 lb)). Smaller samples contain darker altered olivine crystals. 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.
