Wehrlite is anultramafic and ultrabasic rock that is a mixture ofolivine andclinopyroxene. It is a subdivision of theperidotites.
The nomenclature allows up to a few percent oforthopyroxene. Accessory minerals includeilmenite,chromite,magnetite and an aluminium-bearing mineral (plagioclase,spinel orgarnet).[1]
Wehrlites occur as mantlexenoliths and inophiolites. Another occurrence is as cumulate ingabbro andnoritelayered intrusions.[1] Some meteorites can also be classified as wehrlites (e.g.NWA 4797).[2]
Wehrlite is named afterAlois Wehrle.[3] He was born 1791 inKroměříž,Czech Republic (then Kremsier in Mähren) and was a professor at the "Ungarische Bergakademie" (Hungarian Mining School) inBanská Štiavnica,Slovakia (then Schemnitz,Kingdom of Hungary).[4]
