The Archean rocks of the Tarim Craton are mainly exposed in the four marginal basement uplift belts, namely Kuruktagh, North Altyn Tagh, Tiekelike and Dunhuang. The Kuluketage block is located in the northeastern margin of the Tarim Craton, in which Archean rocks with reliable chronology reports are mainly exposed in Korla, Xinger, Xingdi and Pargangtage regions. Archean rocks in the Kuluketage block are mainly composed of felsic orthogneiss (including TTG gneiss) and a small amount of amphibolite enclaves, and the true Archean supracrustal rocks are rare. In this study, SHRIMP U- Pb zircon dating of felsic orthogneiss and quartzite in the Korla area shows that the ages of felsic orthogneiss are 2695±9 Ma and 2705±8 Ma, respectively. The minimum age peak of detrital zircon cores in a quartzite sample is 2513 Ma, suggesting that the quartzite may be Archaean sedimentary rocks. The above rock samples all experienced high- grade metamorphism of 1. 9~1. 8 Ga in the early Paleoproterozoic. Geochemical analysis shows that the protoliths of Neoarchean felsic gneiss in the Kuluketage block are of various rock types, all of which formed in island arc tectonic setting related to subduction. The parent mafic magmas of amphibolites and meta- gabbros may be derived from different geological backgrounds, one part from partial melting of subcontinental mantle wedge under arc, the other from oceanic plate, mainly mid- oceanic ridge basalt. The Archaean rocks of the Kuluketage block have two age peaks of 2.7 Ga and 2.5 Ga, and the 2.7 Ga magmatic event mainly occurred in the western part of the Kuluketage block. The εHf(t) values of zircons are both positive and negative, indicating that crustal growth and reworking coexisted during this period. The whole- rock εNd(t) and zircon εHf(t) values are mainly positive, suggesting significant continental crustal growth in this period.
