Contrasting magma chemistry in the Candelaria IOCG district caused by changing tectonic regimes

Scientific Reports
Iron oxide-copper-gold (IOCG) deposits are a vital source of copper and critical elements for emerging clean technologies. Andean-type IOCG deposits form in continental arcs undergoing extension, and they have a temporal relationship with magmatism ...

Seismic images of the megathrust rupture during the 25th October 2010 Pagai earthquake, SW Sumatra: Frontal rupture and large tsunami [PDF]

The Mentawai segment of the Sumatra subduction zone is locked and likely to produce a large earthquake in the near future. A part of this locked zone ruptured on 12 September 2007 producing twin earthquakes of Mw = 8.5 and 7.9.

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

Geological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Geodynamic modelling of subduction zones : Subduction zone initiation by polarity reversal and main dynamic controls on the stability of single-sided subduction

, 2021
Subduction zones are one of the most widely studied geodynamic settings, representing the primary driver for mantle convection and plate tectonics.

Generation of normal and adakite-like calc-alkaline magmas in a non-subductional environment: An Sr-O-H isotopic study of the Apuseni Mountains neogene magmatic province, Romania [PDF]

, 2007
Neogene magmatism in the Apuseni Mountains of Romania was active between 15 and 7 Ma, with an isolated final eruption at 1.6 Ma. Several groups of magmatic rocks can be distinguished in the province on the basis of ages, trace elements and isotopic ...

Tectono‐Sedimentary Evolution of the Neogene İnegöl Basin (NW Anatolia): Constraints on Transtensional Basin Development at the Junction of the Western Anatolian Extensional Province and the North Anatolian Fault Zone

Geological Journal, EarlyView.
The study outlines the tectono‐sedimentary evolution of the İnegöl Basin in north‐western Anatolia. Basin formation was controlled by interacting extensional and strike‐slip fault systems linked to uplift of the Uludağ Massif. Terrestrial sedimentation from the Miocene to Pleistocene is reconstructed using abundant fossil mammal assemblages that ...

Deep fault sliding rates for Ka-Ping block of Xinjiang based on repeating earthquakes

Open Geosciences
The seismically active Ka-Ping Block within Xinjiang, China, represents a zone of potential earthquake hazards, and existing surface measurements cannot fully reflect the area’s sub-surface slip rates.

Apatite in Carbonatite Preserving Primary Magmatic, Post‐Magmatic Overgrowth, and Post India‐Asia Collision‐Related Hydrothermal Alteration: Evidenced From U–Pb Isotope and Trace Element Geochemistry

Geological Journal, EarlyView.
U–Pb isotope and trace element geochemistry of apatite from carbonatites of Peshawar Plain Alkaline Igneous Province, western Himalaya shows Permo‐Carboniferous magmatism, an additional magmatic pulse during Cretaceous, and post‐magmatic hydrothermal/metasomatism during Oligocene. ABSTRACT U–Pb isotope and trace element geochemistry of apatite combined
