Refining the spatio-temporal distributions of Mesozoic granitoids and volcanic rocks in SE China

, 2020
Combining published age data and geological maps, we provide most updated information about the spatio-temporal distributions of Mesozoic granitoids and volcanic rocks in SE China.

Permo–Triassic granitoids, Hainan Island, link to Paleotethyan not Paleopacific tectonics

, 2020
Hainan Island may have lain at the boundary between the Tethyan and Pacific domains since the late Paleozoic. Permo–Triassic granitoids outcropped on the island provide insight into Mesozoic tectonic evolution and potential dynamics.

Late Mesozoic high-heat-producing (HHP) and high-temperature geothermal reservoir granitoids: The most significant geothermal mechanism in South China

, 2020
Differences in the geothermal regime of continental intraplate regions depend mainly on the amount and distribution of radioactive heat production in crustal rocks.

U–Pb zircon ages and petrogenesis of the Late Cretaceous I-type granitoids in arc setting, Eastern Pontides, NE Turkey

, 2020
The Eastern Pontides Orogenic Belt (EPOB) as a well-preserved ancient magmatic arc situated in the eastern part of the Sakarya Zone and has key importance to allow for proper reconstruction of the geodynamic evolution of the region.

Late Mesozoic granitoids in the Qinling Orogen, Central China, and tectonic significance

Earth-Science Reviews, 2018
The Qinling Orogen in central China is a complex collage built through the closure of the northernmost Paleo-Tethys and the suturing of the Yangtze and the North China cratons. In this contribution, geochronological, geochemical and isotopic data of Late

Archean granitoids: classification, petrology, geochemistry and origin

Special Publications, 2019
This paper describes the petrology, geochemistry and petrogenesis of Archean granitoids. Archean granites define a continuum of compositions between several end members: (i) magmas that originated by partial melting of a range of crustal sources, from ...

Granitoid suites

Geological Journal, 1991
AbstractThe concept of suites within granitoid batholiths must be treated with extreme caution, especially when petrogenic interpretation of identified suites is involved (e.g. infrastructural control of granitoid suite composition). Without stated, necessary, and sufficient operational definitions of the parameters (and their weighting) used in suite ...

Proterozoic Granitoids of Rajasthan

Journal of the Geological Society of India, 2005
Abstract Two granitoid bodies each from Palaeo-, Meso- and Neo-proterozoic periods have been studied for their chemical, petrological and source characteristics The Proterozoic granitoids are megacrystic as well non-megacrystic with variable effect by tectonometamorphic events The Palaeo-proterozoic granitoids are peraluminous ...

Zircon U-Pb geochronology and geochemistry of Late Devonian–Carboniferous granitoids in NW Iran: implications for the opening of Paleo-Tethys

Soviet Economy, 2019
We present zircon U-Pb crystallization ages combined with bulk rock major and trace element geochemistry and Sr-Nd-Pb and zircon in-situ Hf isotopic compositions of the Amand and Moro granitoid intrusions in northwest Iran.

Ultrametamorphism and granitoid genesis

Tectonophysics, 1977
Abstract A model is presented to explain the geochemical and mineralogical characteristics of granitoids and their inclusions. The product of ultrametamorphism is melt + residuum, both of which may move en masse to the site of crystallization. The nature of the source material can be deduced from studies on the granitoids and their inclusions; based
