Early-Devonian intrusive magmatism of the Urals as indicator critical stage Paleozoic history mobile belt

Литосфера, 2015
It is established that during all-Uralian stage of mantle-type magmatism of Early Devonian age (410-393 Ma) the mantle Ordovician-Silurian magmatism was changed by mantle-crustal and crustal types.

Lithospheric Mantle Heterogeneity Drives Delayed Magmatism and Wide Continent‐Ocean Transitions in Rifted Margins

Geophysical Research Letters
The formation of wide, magma‐starved continent–ocean transition (COT) zones remains incompletely understood. We use 2‐D thermo‐mechanical numerical experiments, coupling hydrous mantle melting with parameterized crustal accretion, to explore controls on ...

Relations between extensional tectonics and magmatism within the Southern Oklahoma aulacogen [PDF]

Variations in the geometry, distribution and thickness of Cambrian igneous and sedimentary units within southwest Oklahoma are related to a late Proterozoic - early Paleozoic rifting event which formed the Southern Oklahoma aulacogen.
