Petrogenesis and geodynamic significance of Neoproterozoic (∼925 Ma) high-Fe–Ti gabbros of the RenTso ophiolite, Lhasa Terrane, central Tibet

, 2018
The Precambrian origin and evolution of the Lhasa Terrane remain unclear. Here, we present new zircon U-Pb isotopic and whole-rock geochemical data for the RenTso gabbros of the central Lhasa Terrane.

Paragenesis of magma chamber internal wall discovered in Oman ophiolite gabbros

, 2016
A detailed study in Wadi Farah reveals a singular point in Jebel Dihm (southern Oman ophiolite). Here, we investigated some primitive features of accretion at a fast-spreading ridge that has exceptionally been exempt from hydrous alteration while ...

Timing of deposition, orogenesis and glaciation within the Dalradian rocks of Scotland: constraints from U-Pb zircon ages [PDF]

, 2002
The stratigraphical and structural continuity of the Late Proterozoic Dalradian rocks of the Scottish Highlands is re-examined in the light of new U-Pb zircon ages on the tuffs belonging to the Tayvallich Volcanic Formation (601 ñ 4 Ma), and on the late ...

Zircon Isotopic Constraints on Age, Magma Genesis, and Evolution of the Betic Ophiolites, Nevado-Filábride Complex, Spain

Geosciences
Metabasic rocks (eclogites and amphibolites) from four Betic ophiolite outcrops (Lugros, Almirez, Cóbdar, and Algarrobo), comprising Ol-Px gabbros, dolerites, and MORB-affinity basalts, were studied.
