中文摘要
对南非林波波带中央带Klein Bolayi农场及其周围地区的太古代麻粒岩相表壳组合进行了野外研究,并进行了锆石测年、岩石学特征和Hf-In-锆石同位素特征的研究,旨在建立这些岩石的年龄、岩石成因、原岩鉴定和变质演化。
英文摘要
Field investigations of an Archaean granulite-facies supracrustal assemblage on the farm Klein Bolayi and environs, Central Zone of the Limpopo Belt, South Africa, followed by zircon dating, petrological characterization as well as Hf-in-zircon isotopic characteristics with the aim to establish the age, petrogenesis, protolith identification and metamorphic evolution of these rocks The overall purpose is to elucidate the previously ill-defined ca. 3.2 Ga early Archaean metamorphic history of the Central Zone and its tectonic significance.
