Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites.

The nomenclature allows up to a few percent of orthopyroxene. Accessory minerals include ilmenite, chromite, magnetite and an aluminium-bearing mineral (plagioclase, spinel or garnet).[1]

Wehrlites occur as mantle xenoliths and in ophiolites. Another occurrence is as cumulate in gabbro and norite layered intrusions.[1] Some meteorites can also be classified as wehrlites (e.g. NWA 4797).[2]

Wehrlite is named after Alois Wehrle.[3] He was born 1791 in Kroměříž, Czech Republic (then Kremsier in Mähren) and was a professor at the "Ungarische Bergakademie" (Hungarian Mining School) in Banská Štiavnica, Slovakia (then Schemnitz, Kingdom of Hungary).[4]
