The mid- to late-Neoproterozoic magmatic rocks from the northern margin of the Yangtze Block are major protoliths of high-pressure (HP) and ultrahigh-pressure (UHP) metamorphic rocks in the Dabie–Sulu orogenic belt along the northern margin of the South China Block. Oxygen isotopic compositions of these mid- to late-Neoproterozoic magmatic rocks hold a key to understanding the origin of large-scale...
The age and stratigraphic correlation of the Liantuo Formation in the Yangtze Block have been controversial. Disputes diverge on whether it is correlative with the Xieshuihe Formation, the Fulu Formation, the Chang’an Formation or the Banxi Group. Some radiometric dates have been obtained from the Liantuo Formation but they suffer from inheritance. In this paper, we carried out a detailed SIMS U–Pb...
The Gangbian alkaline complex in the southeastern Yangtze Block (South China) is composed of Si-undersaturated pyroxene syenites and Si-saturated to -oversaturated syenites and quartz monzonites. SIMS zircon U–Pb analyses indicate that the complex was emplaced at 848±4 Ma, during a previously-recognized interval of magmatic quiescence between the ca 1.0–0.89 Ga Sibaoan orogenic magmatism and the ca...
