Principle of Hydrogen Isotope Geochemistry Paleo‐altimeter and its Potential in Reconstructing Paleo‐elevation of the Southeastern Tibetan Plateau

Fengzhen CUI, Jing LIU‐ZENG, Yunshuai LI, Qiang XU, more

Acta Geologica Sinica ‐ English Edition > 98 > 4 > 1051 - 1063

The reconstruction of paleo‐elevation serves a dual purpose to enhance our comprehension of geodynamic processes affecting terrestrial landforms and to contribute significantly to the interpretation of atmospheric circulation and biodiversity. The oxygen (δ18Ow) and deuterium (δDw) isotopes in atmospheric precipitation are systematically depleted with the increase of altitude, which are typical and...

A Novel Three‐stage Tectonic Model for Mississippi Valley‐type Zn‐Pb Deposits in Orogenic Fold‐and‐Thrust Belts

Yucai SONG

Acta Geologica Sinica ‐ English Edition > 98 > 4 > 843 - 849

Mississippi Valley‐type (MVT) Zn‐Pb deposits predominantly form within both orogenic forelands and fold‐and‐thrust belts, yet the mineralization process within the latter tectonic setting remains inadequately understood. This study, through a comprehensive review of MVT deposits across global fold‐and‐thrust belts, introduces a novel model elucidating the mineralization process in the context of tectonic...

Hydro‐uvarovite from Mantle Peridotites of Naga Hills Ophiolite: A Mineral Tracer for Neo‐Tethyan Mantle Wedge Metasomatism

Anisha VERENCAR, Abhishek SAHA, Nilanjana SORCAR, Sohini GANGULY, more

Acta Geologica Sinica ‐ English Edition > 98 > 4 > 867 - 877

Hydrous Cr‐bearing uvarovite garnets are rare in natural occurrences and belong to the ugrandite series and exist in binary solid solutions with grossular and andradite garnets. Here, we report the occurrence of hydrous uvarovite garnet having Cr2O3 upto 19.66 wt% and CaO of 32.12–35.14 wt% in the serpentinized mantle peridotites of Naga Hills Ophiolite (NHO), India. They occur in association with...
