Formation of an Intracontinental Orogen Above the Permo-Triassic Mantle Convection Cell in the Paleo-Tethys Tectonic Realm due to Far-Field Stress Derived From Continental Margins

Frontiers in Earth Science, 2022
The identification of intraplate orogens seemingly poses challenges to the plate tectonic theory. Delineating the formation processes of intraplate orogens can provide clues for the better understandings of the above issue.

Batholith recorded mesozoic multistage tectonic evolution of the South china block: A case study of the guandimiao intrusions

Frontiers in Earth Science, 2022
South China is a well-known grand felsic igneous rocks province. However, it is still controversial and not well understood whether the Mesozoic tectono-magmatic pattern is dominated by the subduction of the paleo-Pacific oceanic plate. In this study, we

Deep-Seated Processes Controlling Mesozoic Differential Metallogeny in the Southern Region of South China: Insights from Hf-Nd Isotope Mapping

Geosciences
The southern region of the South China Block hosts a super-large metallogenic province. However, the Mesozoic differential metallogeny between the southern Cathaysia Block (W-Sn) and the southern Yangtze Block (Au-Sb) remains enigmatic.

Identification of the first Caledonian A-type granitoids in the southern Qin-Hang belt of south China: Tectonic link to early Paleozoic extension

Solid Earth Sciences, 2023
Evolution of the late Ordovician–Silurian Caledonian orogeny (ca. 460–420 Ma) in the South China Block (SCB) remains controversial due to the overprinting Triassic (Indosinian) and Jurassic-Cretaceous (Yanshanian) orogenic tectonics and the absence of ...

Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Quantifying Multi‐Source Sediment Supply in a Tropical Foreland Basin (Oligocene‐Miocene Nyalau Formation, Borneo)

Basin Research, Volume 38, Issue 2, March–April 2026.
Detrital zircon unmixing identifies three sediment sources for the Oligocene–Miocene Nyalau Formation, including a previously unrecognised syn‐depositional component characterised by Oligocene–Miocene volcanic zircons and Neoproterozoic populations absent from established sources.

Segmented accretion: new insights into the convergence between the Yangtze and Cathaysia blocks, as interpreted from 3D magnetotelluric imaging

Earth, Planets and Space
As the Neoproterozoic suture zone between the Yangtze and Cathaysia blocks, the Jiangnan orogen is both a research hotspot and controversial issue. In particular, its formation process and tectonic polarity have been extensively investigated in recent ...

Mineralization Characteristics of the Li‐rich Muscovite Granite in the Mufushan Batholith, Central China: Insights into the Rare Metal Mineralization Models of Batholithic Complex

Acta Geologica Sinica - English Edition, Volume 100, Issue 1, Page 137-155, February 2026.
Abstract Elucidating the mineralization mechanisms of individual granitic stages and tracing magmatic evolution processes are critical for establishing mineralization models of large‐scale batholiths. The Mufushan granitoid batholith, renowned for multistage magmatism and large‐scale rare metal mineralization, mainly comprises biotite, two‐mica, and ...

Metallogeny, Ore‐Controlling Factors, and Deep Prospecting Indicators of Fluorite Deposits in Zhejiang Province, SE China: A Review

Geofluids, Volume 2026, Issue 1, 2026.
Zhejiang Province ranks among China′s premier fluorite‐producing regions, with numerous deposits supplying strategic mineral resources. This paper synthesizes published literature on fluorite deposits in Zhejiang Province. We propose a classification framework dividing the deposits into four major metallogenic districts: Wuyi, Xianju, Lin′an, and ...

Sediment routing from the Red River to the Yinggehai Basin during late Oligocene: detrital zircon fingerprinting of basin-mountain coupling

Frontiers in Marine Science
The Red River, which flows through several tectonic blocks in Southeast Asia, is considered to have formed in response to the Cenozoic tectonic reorganization of the SE Tibetan plateau.
