The Himalayan leucogranites provide a good opportunity to investigate the crustal evolution of the southern Qinghai-Tibet Plateau. In this study, we present zircon U-Pb and monazite U-Th-Pb ages, zircon Hf isotopes and whole-rock Sr-Nd-Pb isotopes and major and trace elements for the Liemai two-mica granite, eastern Himalaya. Together with previously published data we revalued the petrogenesis.

The Cenozoic granites in the Himalayan orogen form one of the largest granite belts worldwide, and are widely accepted to be purely crustal. the absence of external fluids during partial melting). The Conadong two-mica granites in eastern Himalaya only record small B isotope fractionation of 2.5‰ during non-modal partial melting.

The Himalayan leucogranite attracts the attention of the world and has important theoretical and prospecting significances, but its genesis is controversial. In this paper, the geochemistry of whole rock main and trace elements, Sr-Nd-Pb-Hf isotopes, in-situ U-Pb ages of zircon/monazite/xenotime and other accessory minerals, and zircon Hf isotopes of secondary minerals from more than 2000.

Two-mica granites from the Yardoi area are of peraluminous granite with relatively high Na/K and Sr/Y ratios. Such features are distinct from those in the younger leucogranites along the HHCS as well as in the NHGD, and require melting of source consisting dominantly of amphibolite at thickened crustal conditions.

As prototypes of crust-derived remelted S-type granite, Himalayan leucogranites have considerable relevance in crustal evolution and associated metallogeny. However, given their highly differentiated character, the petrogenesis of these rocks has remained controversial. This study reviews the geochemical and isotopic data from >2000 samples of Himalayan Cenozoic granitoids to evaluate their.

Low to medium grade crystalline rocks locally known as Bomdila Group extensively covers the Lesser Himalayan region in Western Arunachal Himalaya. This Group consists dominantly of mylonitic gneisses of granitic composition of Palaeoproterozoic age, named as Bomdila mylonitic gneiss (BMG) and a small body of hornblende bearing granite of Mesoproterozoic age known as Salari granite (SG).

The Himalayas are emerging as a new world-class rare metal metallogenic belt. As prototypes of crust-derived remelted S-type granite, Himalayan leucogranites have considerable relevance in crustal evolution and associated metallogeny. However, given their highly differentiated character, the petrogenesis of these rocks has remained controversial.

Description With a vastly stretching, often changing pattern that resembles the great Himalayan mountain range drawn on a map, Himalaya White is a charming Brazilian granite. On its surface, black speckles and veins overlap patches of pale gray and white, creating intense depth and dimension.

A detailed isotopic study of the Manaslu leucogranite was carried out. A U-Pb age of 25 Ma and a whole rock Rb-Sr age isochron of 18 Ma were obtained, suggesting that the magmatic activity lasted at least 7 Ma. Initial Sr isotopic ratios are very high (0.740 to 0.760) and initial Nd isotopic ratios are low (ɛ Nd in : −13 to −16), and they show the existence of large isotopic variations.

The above data demonstrate that all three suites of two-mica granite from the Yardoi area are of peraluminous granite and unusually rich in CaO (Fig. 5 c). However, granites from the YGD have highest SiO 2 and largest variations in Na 2 O, and those from Dala have highest Al 2 O 3 , whereas those from Quedang have highest MgO as well as FeO.
