Mugearite /ˈmʌɡərt/ is a type of oligoclase-bearing basalt, comprising olivine, apatite, and opaque oxides. The main feldspar in mugearite is oligoclase.[1]

The rock type was first identified at Mugeary on the island of Skye, Scotland by Alfred Harker in 1904.[2] Analysis of a Martian rock found by the Curiosity rover and named "Jake Matijevic"(or "Jake M"), after a NASA engineer, determined that the martian rock was very similar to terrestrial mugearite.[2][3][4][5]
