Age, Sources, and Geological Position of Anorthosites of Precambrian Terranes of Central Asia: Example from the Khunzhilingol Massif, Mongolia

摘要

Large anorthosite massifs (or autonomous anorthosites) are typical magmatic complexes of Early Precambrian structures. They are usually formed at the postorogenic stages of their evolution and serve as indicators of their intraplate activation. These massifs remain enigmatic from the petrological point of view, but provide important information on the geology and evolution of host structures.
