More model informationThis amphibolite is dominated by the minerals hornblende and plagioclase, with minor quartz also present. Due to the prismatic morphology of these minerals, the rock is lineated rather than foliated. The lineation is orientated parallel to the top edge in the initial view - the lineation is more easily observed on the weathered rear surface of the specimen. Close inspection of the left-hand end of the specimen (in initial viewpoint) shows what looks like a massive structure, because you are looking into the lineation.
