“…The 3.3-3.2 Ga inherited zircon cores are also present from the same area, and some tonalite gneisses possibly intruded in the terrane during the same period [18]. Chen et al [20] recently identified emplacement ages of 2.7-2.6 Ga for A-type granites, which is similar to the age of 2693 ± 9 Ma obtained for the granite intrusion of the Yudongzi Group [21] and the protolith age of 2.75-2.70 Ga reported for the Huangluling granulite in the Dabie Mountain [22,23]. In fact, the age data of these three groups were also recorded in detrital zircons from metasedimentary rocks [5][6][7][8][9] and inherited zircons from igneous rocks [10][11][12][13][14] in different areas of the Yangtze craton, suggesting that the 3.3-3.2 Ga, 2.95-2.9 Ga and 2.7-2.6 Ga eras are important periods for the continental crustal growth in the Yangtze craton.…”

“…The oldest emplacement age of ~2.95-2.9 Ga in the Kongling Group comes from TTG gneisses of the high grade metamorphic terrane [15][16][17]19,20]. The 3.3-3.2 Ga inherited zircon cores are also present from the same area, and some tonalite gneisses possibly intruded in the terrane during the same period [18].…”

“…However, the supporting evidence mainly comes from U-Pb studies of detrital zircons in metasedimentary rocks [5][6][7][8][9] or inherited zircons in igneous rocks [10][11][12][13][14]. The Archean age information obtained for the exposed basement rock series are mostly from the Kongling high grade metamorphic terrane at the northern margin of the Yangtze craton [15][16][17][18][19][20], with sporadic reports from the granulites in the Yudongzi Group and the Dabie Mountains [21][22][23]. To date, three main episodes of Archean magmatic event in the Yangtze craton have been recognized, i.e.…”

A ∼2.5 Ga magmatic event at the northern margin of the Yangtze craton: Evidence from U-Pb dating and Hf isotope analysis of zircons from the Douling Complex in the South Qinling orogen

The poorly studied Douling Complex is a crystalline basement that developed in the Neoproterozoic-Paleozoic weakly metamorphosed to non-metamorphosed strata at the South Qinling tectonic belt. Five banded dioritic-granitic gneiss samples from the Douling Complex were chosen for LA-MC-ICPMS U-Pb zircon dating, which yielded protolith emplacement ages of 2469 ± 22 Ma, 2479 ± 12 Ma, 2497 ± 21 Ma, 2501 ± 17 Ma and 2509 ± 14 Ma, respectively. An important peak age of ~2.48 Ga was also obtained for a metasedimentary rock in the same region. These discoveries suggest the occurrence of magmatic activity of 2.51-2.47 Ga at the northern margin of the Yangtze craton. The age-corrected ε Hf (t) values obtained from in situ zircon Hf isotopic analysis are mainly between −5.5 and +0.3, and the two-stage zircon Hf model ages range from 3.30 to 2.95 Ga. Considering two important periods of ~3.3-3.2 Ga and ~2.95-2.90 Ga for the continental crustal growth in the Yangtze craton, we infer that the dioritic-granitic gneisses from the Douling Complex are the products of reworking of Paleo-to Mesoarchean crust at the northern margin of the Yangtze craton at ~2.5 Ga. In addition, metamorphic ages of 837 ± 8 Ma and 818 ± 10 Ma were obtained for zircon overgrowth rims from a dioritic gneiss and a metasedimentary rock, indicating that the main phase amphibolite facies metamorphism of the Doulng Complex occurred during the Neoproterozoic, although its geological meaning remains ambiguous.

The Yuli metamorphic belt has been the topic of petrological and geochronological studies for over 40 years and has been interpreted as a Cretaceous mélange. Our study utilizes zircon U‐Pb dating of schist and exotic blueschist blocks in the Yuli belt. These new ages indicate that these metamorphic rocks are actually middle Miocene in age and may represent the deeper structural levels of an accretionary prism. Several distinctive detrital zircon U‐Pb age populations are recognized from 14 siliceous schists of mélange‐hosted rocks that are similar in age population to the Cretaceous, Eocene‐Oligocene, and Miocene strata of Taiwan. The wide range of ages is interpreted as a product mixing of various sedimentary strata prior to metamorphism. Three blueschists of a volcanic‐arc protolith enclosed within the host rocks yield crystallization ages of 15.4 ± 0.4, 15.5 ± 0.3, and 16.0 ± 0.2 Ma based on zircon U‐Pb dating. In consideration of the new data regarding the Cretaceous‐Miocene host rocks and the middle Miocene exotic blueschist blocks, it strongly suggests that the Yuli belt formed at deeper levels of an accretionary wedge during subduction of South China Sea oceanic crust at the middle‐late Miocene. Subsequently, the rapid uplift of the metamorphic belt was probably related to doubly vergent wedge extrusion due to the Pliocene arc‐continent collision.
