Abstract Early Cretaceous granitoids are widespread on the Tibetan Plateau and record the tectonic evolution of several Tethyan oceans. We describe Early Cretaceous high-Mg (Mg # > 50) and low-Mg (Mg # Pb dating reveals two episodes of granitoid emplacement at ~122 and ~117 Ma. High-Mg series rocks have higher Mg # and compatible element concentrations (e.g., Cr and Ni) than low-Mg series samples. Their Mg # and compatible element abundances are also elevated relative to an experimental melt gen...

Abstract Cretaceous granites are widely exposed in the Tengchong Terrane that is the southern extension of the Tibetan Plateau, resulting from the evolution of the Tethys. They, therefore, play a critical role in deciphering the Tethys evolution and the growth of the Tibetan Plateau. In this paper, we present new zircon U Pb dating and Hf isotopic results, along with whole-rock elemental and Sr Nd isotopic data of the granitoids from the Lushui-Pianma (LP) batholith and its mafic enclaves and th...

Abstract Triassic granites are widely exposed in the central Qiangtang, northern Tibetan Plateau. They, therefore, made an important contribution to the growth of the Tibetan Plateau. In this paper, we present zircon U–Pb dating and Hf isotopic results, and whole-rock elemental and Sr–Nd isotopic analyses of the Dongdashan (DDS) batholith in the central Qiangtang in order to understand their petrogenesis and tectonic setting. LA-MC-ICP-MS zircon U–Pb results show that the DDS batholith was empla...

Abstract Strongly peraluminous (SP) granites have A/CNK (molecular Al 2 O 3 /(CaO+Na 2 O+K 2 O)) ratios >1.1, indicating a predominant origin from the partial melting of metasedimentary rocks. However, an increasing number of studies have documented that mantle-derived magmas can also be involved in the petrogenesis of some SP granites. This is the case in the Dulong batholith in the southeastern Yunnan province, southwestern South China Block, which is typically composed of SP granitic rocks wi...

Abstract Zircon U–Pb ages and Hf isotopic composition of Mesozoic intrusive rocks from the Yidun terrane were systematically investigated in order to decipher the geodynamic setting of magmatism and their relationship with Cu-polymetallic mineralization in the Eastern Tibetan Plateau. Zircon U–Pb dating results on seven granitoid rocks and four diorite samples indicate that the Mesozoic plutons from the Yidun terrane were emplaced in the period of 224–214 Ma with a peak at ∼216 Ma. Zircon Hf iso...

Abstract High Fe–Ti basic rocks (FeOt > 12 wt% and TiO 2 > 2 wt%) are rare in the geological record and display a different evolutionary trend (the ‘Fenner’ trend) from the normal ‘Bowen’ trend of SiO 2 enrichment. In this paper, we present geochronological, geochemical and Sr–Nd isotopic data for the Fe–Ti-rich gabbros from western Shandong within the Eastern Block of the North China Craton. Zircon U–Pb dating indicates that they were emplaced at ∼1.21 Ga. All high Fe–Ti gabbros are characteriz...

Siliceous high-Mg basalt (SHMB) is a rare rock type that occurs mainly at or near the Archean–Proterozoic boundary. It shares some geochemical similarities with Phanerozoic boninites, but there is a clear distinction. Whether the petrogenesis of SHMB resembles that of Phanerozoic boninites or is related to the komatiitic magmatism is controversial. Neoarchean SHMBs are identified for the first time from the Taishan granite–greenstone terrane within the Eastern Block of the North China Craton (NC...

Abstract The southern Lancangjiang magmatic belt is an important component of the Triassic San-Jiang igneous zone in Southwestern China and is mainly composed of the Lincang (LC) batholith and a Mesozoic volcanic belt that contains abundant rhyolites. Our new LA-ICP-MS zircon U–Pb results, together with previous SHRIMP and LA-ICP-MS ages, define two emplacement ages for the Lincang batholith: at ~ 230 Ma and ~ 220 Ma, corresponding to the eruption times of volcanic rocks of the Manghuai and Xiao...

Abstract A series of Late Neoarchean high Ba–Sr granites with a potassium-rich signature has been identified from the Taishan granite–greenstone terrane (TSGT), within the Eastern Block of the North China Craton (NCC). LA-ICP-MS zircon dating shows that the Wanghailou, Hujiazhuang and Xiajiazhuang granitic intrusions were emplaced at ~ 2.54 Ga, ~ 2.52 Ga and ~ 2.47 Ga, respectively. Geochemically, they are alkali-rich, with high K 2 O contents and high K 2 O/Na 2 O ratios, revealing their high-p...
