Early Cretaceous mafic rocks are first reported in the northern Guangxi region from the western Qin-Hang belt in the interior South China Block. A systematic investigation of zircon U–Pb dating, whole-rock geochemistry, Sm–Nd isotopes and zircon Hf–O isotopes for these mafic rocks reveals their petrogenesis and the mantle composition as well as a new window to reconstruct lithospheric evolution in interior South China Block during Late Mesozoic. Zircon U–Pb dating yielded ages of 131 ± 2 Ma to 136 ± 2 Ma for diabase and gabbro from Baotan area, indicating the first data for Early Cretaceous mafic magmatism in the western Qing-Hang belt. These mafic rocks show calc-alkaline compositions, arc-like trace element distribution patterns, low zircon εHf(t) of − 9.45 to − 6.17 and high δ18O values of + 5.72 to + 8.09‰, as well as low whole-rock εNd(t) values of − 14.27 to − 9.53. These data suggest that the studied mafic rocks are derived from an ancient lithospheric mantle source that was metasomatized during Neoproterozoic subduction. Thus, the occurrence of these mafic rocks indicates a reactivation of Neoproterozoic subducted materials during an extension setting at Late Mesozoic in the western Qin-Hang belt, an old suture zone that amalgamates the Yangtze and Cathaysia blocks.

“…Multiple episodes of shortening and stretching occurred in Southeast China during the Late Mesozoic (Chu et al, 2019;Ji et al, 2018;Li et al, 2010Shu et al, 2009;Yu et al, 2020;Zhou et al, 2006). Moreover, although regional extension during the Cretaceous possibly occurred from the Early Cretaceous and exerted a stronger influence than that during the Jurassic, numerous examples have provided evidence that intracontinental extension in eastern South China initiated during the Early Jurassic (Cen et al, 2016;Gan, Wang, Qian, Bi, & He, 2017;Yu et al, 2010Yu et al, , 2020. Chu et al, 2019;Ji et al, 2018;Li et al, 2020).…”

Cretaceous syntectonic growth strata in terrigenous basins in Southeast China have scarcely been reported in previous studies. This work focusses on the growth strata of the Early Cretaceous red beds in the East Yangtze Block (EYB), especially in the Huangshan Basin in southern Anhui Province, to help determine the Late Mesozoic tectonic domain and the precise timing of the initiation of extensional tectonics in Southeast China. Field observations show that the dip angles of the red conglomerate-bearing sandstones from the lower part of the Huizhou Fm. vary from 49 to gentle dips towards the basin centre and that the visible and estimated thickness within a single bed increases slightly downward from the upper to the lower part. These characteristics indicate that the sedimentary area of the Early Cretaceous Huizhou Formation (Fm.) has undergone an extensional process with the expansion and deepening of the sedimentary basin by rotation of the border surface (limb) and thus deposited the extension growth strata simultaneously with (or closely after) the 139 Ma Shiling volcanic activity. Caused by a NW-SE-oriented extensional stress field since ca. 140 Ma, a model in which NE-SW-oriented tectonic lines transform to E-W-trending tectono-magmatic belts by intersecting and inheriting the previous E-W-trending tectonic fabrics is established in the present work. Consequently, these phenomena are influenced by Palaeo-Pacific Plate rollback and the inheritance of astructural framework from the regional basement strata and deformation series.
