6. Conclusions
- The Jiamanhaba, Amulagong and Tiemulete pegmatites were emplaced correspondingly at approximately 261, 373, and 360 Ma. These results indicated that the Jiamanhaba pegmatites were of Permian age, whereas those of the Amulagong and Tiemulete were Devonian.
- The εHf(t) values of 2.87–7.39, two-stage model ages of 900–1171 Ma and δ18O values of 9.55‰–15.86‰ that were obtained from samples of the Amulagong and Tiemulete pegmatites suggested that these were derived from anatexis of mature sedimentary rocks deep in the crust. In contrast, the Jiamanhaba pegmatite samples produced εHf(t) values of 2.87–4.94 and δ18O values of 6.05‰–7.32‰, which indicate the addition of minor amounts of mantle/juvenile materials to the original magma.
- Using a combination of available geochronological and Hf-O isotopic data of felsic igneous, sedimentary, and metamorphic rocks that occur in the Chinese Altay, the formation of the Jiamanhaba pegmatite was assigned to a post-collision tectonic setting, where intensive mantle–crustal interactions occurred in the magma source region. In contrast, the Amulagong and Tiemulete pegmatites were formed in a syn-collision tectonic setting, and juvenile or mantle materials that were produced through the slab window were incorporated in the initial magma.
- This paper puts forward an independent petrogenesis model of pegmatite in Chinese Altay, that is, the genesis of deep melting, which is different from the previous hypothesis that the pegmatite in Chinese Altay consists of fractionation products of granites during the late fractionation stage and provides reliable evidence for the deep melting of pegmatite. The Hf-O isotopic data of pegmatite and granites and sedimentary rocks in this region reveal the tectonic evolution of the region from Devonian to Permian, and they put forward the closing time of the Irtysh–Zaisan Ocean at about 300 Ma in the Late Carboniferous. The Hf-O isotope data of pegmatite provide a new perspective for revealing the tectonic setting of pegmatite formation, which in turn confines the petrogenesis of pegmatite. The coupling of the two relations provides a reliable guarantee for the study of petrogenesis of pegmatites in different periods in the Chinese Altay.
