Low-δ18O A-type granites in SW China: Evidence for the

Here we provide evidence for plume-slab interaction mainly based on in situ zircon Hf-O isotope analyses, as well as whole-rock elemental and Sr-Nd-Hf isotope analyses, on the Late Permian and Early Triassic A-type granites on the margin of the Emeishan LIP in SW China. These granites show typical A-type geochemical The southeast coastal areas in China have distributed lots of granite outcrops of different periods. Previous research has shown that granite geothermal reservoirs are also distributed under sedimentary basins in these areas, such as in Zhangzhou basin. Therefore, granites with fractures buried in deep can be used as a potential deep geothermal reservoir in Frontiers Geological Characteristics and Distribution of Granite

Origin of the Low δ18O Signals in Zircons from the Early Springer

The origin of low δ18O signals in zircons from the Early Cretaceous A-type granites in eastern China has long been disputed. It is uncertain whether the 18O-depleted features were inherited from high-temperature hydrothermal altered source rock or resulted from water-rock interaction after emplacement.

Factors controlling the distribution of granite reservoirs of

Since the Proterozoic, granites in the South China Plate have grown increasingly younger, and some granites were distributed in the opposite (landward) direction as the tectonically active zones migrated southeastward (oceanward) overall. Consequently, multiphase composite granites are developed extensively in South China The Borneo is bounded to the north by South China Sea and Philippines, to the east by Sulu Sea, Celebes Sea and Sulawesi, to the south by Java Sea, and to the west by Malaysia and Sumatra (Figure 1(a)). This island is usually divided into five segments, including SW Borneo, Kuching zone, Sibu zone, Miri zone, and East Borneo (Figure 1(b); Late Cretaceous Granitoids along the Northern Kuching Zone

Triassic granites in South China: A geochemical perspective on

Triassic granites in South China are grouped into five types based on their mafic minerals and geochemical features. • The Triassic granites and their coeval magmatic rocks are distributed in three different zones in South China. • The Triassic granites were mainly originated from the Neoproterozoic sedimentary and igneous rocks. •Late Jurassic (~ 160 Ma) granitoids are widely distributed across the South China Block. These granitoids are mainly biotite granites, with subordinate amphibole-bearing and two-mica or muscovite-bearing granites. Previous studies have shown that a clear negative correlation exists between SiO2 and P2O5 contents in the amphibole Late Jurassic Maofengshan two‐mica granites in Guangzhou, South China
