New SHRIMP and ID-TIMS dating results in this study reveal that the widespread Early-Neoproterozoic granites in the Qinling orogen were emplaced mainly between ∼960 and ∼900Ma. Major elements, mineral compositions, and trace elements data also indicate that all these Early-Neoproterozoic granites are characterized by the features of crust-derived and typical continent–continent syn-collisional granites...
New ion microprobe U-Pb zircon ages, as well as some geochemical and isotopic analyses, for key igneous units within the central part of the West Congo belt are integrated with geological information to provide an updated geological map (1:1 000 000 scale) and a synthetic type cross-section of the belt, as well as an updated lithostratigraphic chart of the 'West Congo Supergroup'. Three Neoproterozoic...
