About Mugearite
A volcanic rock, often exhibiting flow texture, containing small phenocrysts of olivine, augite and magnetite in a matrix of oligoclase, augite and magnetite with interstitial alkali feldspar. Now defined chemically as the sodic variety of basaltic trachyandesite where (Na2O-2)>K2O.
Usually described visually as a basaltic rock.
