Mantle dynamics and Cretaceous magmatism in east-central China: Insight from teleseismic tomograms

, 2015
Both the rich mineralization in the Lower Yangtze Block (LYB) and the post-collisional mafic rocks in the Dabie Orogen (DBO) are closely related to the Cretaceous magmatism in east-central China.

Restoring the Missing Late Cretaceous Arc of Iran

Geochemistry, Geophysics, Geosystems
Persistent arc magmatism archives fluid transport and mantle partial melting in subduction zones. However, arc magmatism often exhibits different magmatic records along the strike, as seen in the Tethyan orogenic belt.

Current understanding of the Sava Zone of the Balkans: A magmatic perspective [PDF]

Geološki Anali Balkanskoga Poluostrva
The Sava Zone (SZ) forms a key tectonic boundary between Europe-derived and Adria-derived continental units in the central Balkans and hosts a discontinuous belt of Late Cretaceous volcanic and plutonic rocks whose geo-dynamic significance remains ...

Petrogenesis of the Cretaceous Intraplate Mafic Intrusions in the Eastern Tianshan Orogen, NW China

Frontiers in Earth Science, 2021
In this study, we conducted zircon U-Pb dating, and whole-rock geochemical and Sr-Nd isotope analyses on the Late Mesozoic dolerite dykes in the Bailingshan Fe deposit (Eastern Tianshan Orogen, NW China) to unravel their petrogenesis and regional ...

Extension-driven evolution of magmatic systems in slab-top basins: insights from the Timok magmatic complex, Serbian Carpathians

Frontiers in Earth Science
Slab-top basins represent key archives of the interaction between subduction dynamics, lithospheric extension, and magmatism. This study presents the first basin-scale tectono-magmatic model for the Late Cretaceous evolution of the Timok Magmatic Complex

Mid-Cretaceous extensional magmatism in the Alborz Mountains, north Iran; geochemistry and geochronology of Gasht-Masuleh gabbros

Swiss Journal of Geosciences, 2023
In the Gasht-Masuleh area in the Alborz Mountains, gabbroic magma intruded Palaeozoic metasediments and Mesozoic sediments and crystallised as isotropic and cumulate gabbros.

Arc Magmatism Controlled by Switches in Tectonic Style: Insights From the NE Asian Margin in the Cretaceous

Geophysical Research Letters
A relation between tectonics and arc magmatism has been proposed in the west Pacific‐type accretionary orogens, but the specific mechanism remains unclear. This study examines the Cretaceous records in NE Asia in order to unravel this link.

Late Cretaceous Intraplate Mafic Dyke Swarms in the East Kunlun Orogen, Northern Tibetan Plateau: Implications for Lithospheric Reactivation and Early Surface Uplift

Geosciences
The Cretaceous represents a key period in the geodynamic evolution of the Tibetan Plateau and the initial development of its paleotopography. While widespread orogenesis and magmatism associated with the Lhasa–Qiangtang collision are well documented in ...

Orthopyroxene-enrichment in the lherzolite-websterite xenolith suite from Paleogene alkali basalts of the Poiana Ruscă Mountains (Romania)

Geologica Carpathica, 2015
In this paper we present the petrography and geochemistry of a recently collected lherzolite-websterite xenolith series and of clinopyroxene xenocrysts, hosted in Upper Cretaceous–Paleogene basanites of Poiana Ruscă (Romania), whose xenoliths show ...

Jurassic–Paleogene intraoceanic magmatic evolution of the Ankara Mélange, north-central Anatolia, Turkey [PDF]

Solid Earth, 2014
Oceanic rocks in the Ankara Mélange along the Izmir–Ankara–Erzincan suture zone (IAESZ) in north-central Anatolia include locally coherent ophiolite complexes (~ 179 Ma and ~ 80 Ma), seamount or oceanic plateau volcanic units with pelagic and reefal ...
