The development of the Ingul megablock of the Ukrainian Shield during the formation of the Novoukrainsky and Korsun-Novomirgorod Plutons

Геофизический журнал, 2013
Analysis of geological structure and the studies of composition of magmatic complexes of the Ingul block of the Ukrainian Shield makes possible to come to some conclusions on its deep structure during the period of 2,1-1,7 Ga.

Birth of an ocean in the Red Sea: Initial pangs

Geochemistry, Geophysics, Geosystems, 2012
We obtained areal variations of crustal thickness, magnetic intensity, and degree of melting of the sub‐axial upwelling mantle at Thetis and Nereus Deeps, the two northernmost axial segments of initial oceanic crustal accretion in the Red Sea, where ...

Geochemical Insights into Crustal Melting in the Bhutan Himalaya [PDF]

, 2016
Crustal melting and granitic intrusions are characteristics of many continental collision zones. The processes, sources and timing of melt generation in collision zones are critical to understanding crustal and tectonic evolution. In the Himalaya, multiple Oligocene-Miocene leucogranite bodies intrude the Greater Himalayan Series (GHS), a lithotectonic

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 ...

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Late Pleistocene Volcanic Rocks From Tengchong Volcanic Field at SE Tibetan Plateau: Constraints on Petrogenesis and Mantle and Crustal Processes

Geological Journal, EarlyView.
Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...
