Mugearite (/ˈmʌɡiəraɪt/) is a type of oligoclase-bearing basalt, comprising olivine, apatite, and opaque oxides. The main feldspar in mugearite is oligoclase.[1]
Mugearite is a
basaltic trachyandesite.[2]
Examples
Western Scotland
Mugearite was first identified at
period of the Earth's geological history, when the North Atlantic Ocean opened
between Europe and North America.
Oceanic islands
Mugearite has been erupted by the volcanoes of some oceanic islands at hotspots. Examples are Hawaii, Ascension Island, Saint Helena, Réunion, Mauritius and Tahiti.[5]
Mars
Analysis of a
Martian rock found by the Curiosity rover and named "Jake Matijevic" (or "Jake M"), after a NASA engineer, determined that this Martian rock is very similar to mugearite erupted on Earth.[3][6][7][8]
