Geological Journal, EarlyView.Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

TektonikaThe interaction between the NE-SW striking Main Ethiopian Rift (MER) and the E-W oriented Yerer-Tullu Wellel Volcano-tectonic lineament (YTVL) represents one of the least understood tectonic problems in the East African Rift System.

Geochemistry, Geophysics, Geosystems, 2021 The Havre Trough (HT) backarc basin in the southwest Pacific is in the rifting stage of development. We distinguish five types of basalt there based on their amount and kind of slab component: backarc basalts (BAB) with little or no slab component ...

Permian-Triassic Rifting Stage
, 2019 International audienceThe Permian-Triassic rifting represents the first of the two Mesozoic rifting stages recorded in the Iberian Peninsula. Its first phases of development started during the Early Permian, and were linked to the beginning of the break ...

Rifting Venus: Insights From Numerical Modeling [PDF]
, 2023 Venus is a terrestrial planet with dimensions similar to the Earth, but a vastly different geodynamic evolution, with recent studies debating the occurrence and extent of tectonic-like processes happening on the planet.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen
Geological Journal, EarlyView.By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

The Southwestern Rift of Africa: isotopic evidence of early-stage continental rifting
Frontiers in Earth ScienceHelium and carbon isotope data (3He/4He = 0.14–0.17 R/Ra; δ13C(CO2) = −3.9‰) from hydrothermal springs within the Kafue Rift of Zambia provide the first geochemical characterization of thermal springs along a broad extensional zone connecting the African

Rapid microplate rotations and backarc rifting at the transition between collision and subduction
, 2005 Using global positioning system velocities from convergent plate boundaries in Papua New Guinea, New Zealand, Tonga, Vanuatu, and the Marianas, we note a spatial correlation between rapid tectonic block rotations and the transition from subduction to ...

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin
Geological Journal, EarlyView.Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.
