Reintepretation of Lampung Cretaceous-Paleogene Granitoids Genesis and Its Tectonic Implications: Reintepretasi Genesa Pembentukan Granitoid Lampung Berumur Kapur-Paleogen dan Implikasi Tektoniknya

, 2022
Granite in Lampung Province is widely exposed but not much has been discussed so that it is still causing debate, especially in the context of the tectonic episode of its formation. This study aims to reconstructed formation of the Lampung granitoid in a

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

New data on geochemical features, fluid mode, age and potential ore content of granitoids of Isherim anticlinorium (North Ural)

Литосфера, 2018
Granitoids of Ishirim anticlinorium which is one of the major Precambrian structures of the North Urals, are poorly studied by modern geochemical and isotope-geochronological methods that led to the existence of different points of view on formation ...

Development of Arsenopyrite Reference Materials (Sacra and Niko) for In situ Multiple Sulfur Isotope Measurement

Geostandards and Geoanalytical Research, EarlyView.
Key Points New arsenopyrite reference materials (Niko and Sacra) for in situ multiple sulfur isotope measurement. Niko and Sacra are homogenous, near‐stoichiometric arsenopyrite. Niko serves as a primary matrix‐matched reference material, with lower measurement repeatability; Sacra is recommended as a secondary reference and quality control material ...

Physicochemical conditions of the formation of the Larino granite-gneiss dome (South Ural)

Georesursy
The Larino granite-gneiss dome is located on the border of the Aramil-Sukhtelya and Magnitogorsk megazones and is a two-headed anticlinal structure, the nuclear parts of which are composed of granitoids of the Pervomai and Larino massifs, and their ...

Metamorphic or Igneous Zircon? Classification Through Rare Earth Elements, Machine Learning and Logistic Regression

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Zircon is a common, highly refractory accessory mineral found in sedimentary, igneous and metamorphic rocks that forms through various processes (e.g., magmatic, hydrothermal, metamorphic growth and recrystallization). Trace element compositions of detrital zircon have been widely applied to understanding tectonic processes and continental ...

Secular Variation of Early Cretaceous Granitoids in Kyushu, SW Japan: The Role of Mélange Rocks as a Possible Magma Source

Frontiers in Earth Science, 2020
The Early Cretaceous volcanic-arc granitic rocks from Kyushu, SW Japan are contemporaneous with the granitic rocks of the Yanshan Orogeny (SE China) along the eastern Eurasian continental margin. The secular geochemical variations of the whole-rock major

U–Pb Dating of Cambrian Magmatism in the Pinerolo‐Sanfront Unit, Dora‐Maira Massif (Western Alps)

Terra Nova, EarlyView.
ABSTRACT The Pinerolo‐Sanfront Unit (PSU), the structurally lowest tectonic unit of the Dora‐Maira Massif (Western Alps), has been regarded as a monocyclic unit composed of Permo‐Carboniferous sediments and Permian granitoids that were metamorphosed during the Alpine orogeny.

Zircon Inheritance Refines the Cambrian Orogenic Architecture of Southeast Australia

Tektonika
The Selwyn Block is one of the few accreted terranes identified in the vast Paleozoic Tasmanides of eastern Australia and its incorporation into this orogen marks a first-order event in the tectonic evolution of the Pacific margin of Gondwana.
