Based on the isotope-geochronological (zircons, U-Pb method), petrogeochemical, and structural petrologic data, following paper provides a detailed description of characteristics Late Paleozoic basic granitoid magmatism in eastern part Kaakhem magmatic area (Eastern Tuva). During formation Shivey alkaline-granitoid Chadal gabbroid massifs period 292–283 Ma, there were revealed two stages contra...

Changes in sediment flux to continental margins are commonly interpreted terms of tectonic growth topography or climatic change. Here, we show that variations yield from orogenic systems, previously considered as resulting climate change, drainage reorganisation mantle processes can be explained by intrinsic mechanisms mountain belt/foreland basin systems naturally evolving during post-orogenic...

Ophiolites of the Alpine belt derive from closure Mesozoic Tethys Ocean that was interposed between palaeo-Europe and palaeo-Adria continental plates. The orogeny has intensely reworked oceanic rocks into metaophiolites with various metamorphic imprints. In Western Alps, continental-derived units are distributed within two paired bands: An inner band where subduction-related high-pressure (HP) ...

The Caledonian orogenic belt of northern Britain hosts some significant quartz vein-hosted gold deposits. However, as in orogenic belts worldwide, the relationship between gold mineralization and regional tectonics, magmatism, and metamorphism is a matter of debate. This is primarily due to the absence of precise temporal constraints for the mineralization. Here we report high-precision 40Ar/39...

The application of big data is great significance to the quantitative study on provenance. In this paper, taking bauxite in Yanlong area, western Henan, as an example, detrital zircon U-Pb age obtained by Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) are used results show that Caledonian and Sibao Jinning zircons from North Qinling Orogenic Belt (NQOB). contrast, Lvlia...
