Field investigations of granulite-facies supracrustal assemblage on the farm Klein Bolay, Central Zone of the Limpopo Belt, South Africa, followed by zircon dating, petrological characterization as well as Sm-Nd whole-rock and Hf-in-zircon isotopic characteristics with the aim to establish the age, petrogenesis and metamorphic evolution of these rocks The overall purpose is to elucidate the previously ill-defined Archaean metamorphic history of the Central Zone.

对南非林波波带中心地带Klein Bolay农场麻粒岩相表壳岩组合进行了实地调查，随后进行了锆石定年、岩石学表征以及Sm-Nd全岩和Hf-in-锆石同位素特征，目的是确定年龄，岩石成因和变质演化的总体目的是阐明以前生病，确定了中央带的中生代变质史。
