The Proterozoic geological history of the Irumide belt

The geochronological data presented in this thesis show that the Irumide belt includes a Palaeoproterozoic basement complex comprising units as old as 273 Ga but mostly made up of granitic gneisses ranging in age between 205 and 193 Ga while granitic and volcanic units of the Bangweulu block to the northwest were dated at 187186 Ga

New UPb zircon geochronology of the ChomaKalomo

The ChomaKalomo Block is a northeast trending Mesoproterozoic terrane loed in southern Zaia It is composed of as yet undated gneissic basement with a highgrade metamorphosed supracrustal metasedimentary sequence which is intruded by hornblende granites and gneisses of the ChomaKalomo Batholith that is dated between ca 137 and 1
