The birth of the Sava Suture Zone: The early geological observations and the context of bimodal magmatism (southern Belgrade outskirts; Anđelković, 1973) [PDF]
Geološki Anali Balkanskoga Poluostrva, 2022 This paper presents one of the significant results of the research of Prof. Dr. Milodrag Anđelković. The study underlines the first field record providing the evidence of the Upper Cretaceous bimodal magmatism that eventually led towards the definition ...

Magmatism and tectonic evolution of West Antarctica
Dizhi lixue xuebao, 2021 West Antarctica is mainly composed of five distinct micro-continental blocks, namely Haag Nunataks, Antarctic Peninsula, Thurston Island, Marie Byrd Land and Ellsworth-Whitmore Mountains. In order to understand the geological evolution of West Antarctica,

The Van Microplate: A New Microcontinent at the Junction of Iran, Turkey, and Armenia
Frontiers in Earth Science, 2021 In northwestern Iran, magmatic activity occurred during three main intervals: The Cretaceous, Eocene, and Miocene-Quaternary. The first two phases of magmatic activity are more consistent with arc-type magmatism on an active continental margin; whereas ...

Stratigraphic and Spatial Extent of HALIP Magmatism in Central Spitsbergen
Geochemistry, Geophysics, Geosystems, 2022 Rapid extensive magmatism may have a profound effect on global climate by liberating and releasing greenhouse gases to the atmosphere through contact metamorphism of lithologically heterogeneous host rocks and degassing of magma and associated lava flows.

Geochemical and Isotopic Evolution of Late Oligocene Magmatism in Quchan, NE Iran
Geochemistry, Geophysics, Geosystems, 2021 Magmatic activity that accompanied the collision between Arabia and Eurasia at ∼27 Ma, provides unique opportunities for understanding the triggers and magma reservoirs for collisional magmatism and its different styles in magmatic fronts and back‐arcs ...

Spatial- temporal relationship of mineralization and magmatism in the Mazraeh polymetallic deposit (north of Ahar, Eastern Azarbaijan province) [PDF]
پترولوژی, 2020 The Sheyvar-Dagh batholith, one of the most important intrusive bodies in northwest Iran, intruded the Upper Cretaceous and the Eocene volcano-sedimentary sequences and associated with some Cu- Fe (±W±Au) mineralization.

Applied Sciences, 2022 Typical stratiform-like cassiterite–sulfide orebodies formed at 160–150 Ma cut by a steep hydrothermal vein-type orebody were discovered in the Xianghualing tin–polymetallic orefield, which implied a new phase of magmatism and mineralization later than ...
