Mugearite () is a type of oligoclase -bearing basalt , comprising olivine , apatite , and opaque oxides. The main feldspar in mugearite is oligoclase.[1]
Mugearite is a sodium -rich member of the alkaline magma series . In the TAS classification of volcanic rock, mugearite is classified as sodium-rich basaltic trachyandesite .[2]
Examples
[ edit ]
Western Scotland
[ edit ]
Mugearite was first identified at Mugeary on the island of Skye , Scotland by Alfred Harker in 1904.[3] Outcrops of mugearite also occur on the island of Mull . These examples of mugearite were formed during a period of continental flood basalt [4] Paleogene period of the Earth's geological history, when the North Atlantic Ocean opened between Europe and North America.
Oceanic islands
[ edit ]
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
[ edit ]
Analysis of a Martian rock found by the Curiosity rover"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]
