英文摘要	The late Neoarchean supracrustal rocks of the Anshan-Benxi (AnBen) terrane in the northeastern part of the North China Craton (NCC) have important regional tectonostratigraphic implications for the development of large-scale banded iron formations (BIFs). These supracrustal rocks underwent polyphase deformation and upper greenschist to upper amphibolite facies metamorphism and are subdivided into two main lithotectonic units in terms of differing ages, metamorphic grades, and lithological assemblages: the Benxi unit (similar to 2.56 - 2.53 Ga) composed of tholeiitic to transitional mafic rocks with minor siliciclastic sedimentary rocks, and the Anshan unit (similar to 2.53-2.51 Ga) consisting of siliciclastic sedimentary rocks with minor tholeiitic mafic rocks. In this study, we report the results of field investigations and petrographic, whole-rock major and trace element geochemical and Sm-Nd isotopic analyses, as well as zircon U-Pb-Hf-O isotopic analyses for these volcano-sedimentary rocks, and integrate the results with previously published data to provide a new geodynamic synthesis for the setting of the BIFs.
