Petrogenesis of Miocene to Quaternary primitive basaltic magmas in the area of Lake Van (East Anatolia, Turkey): a case for relamination of mantle lithosphere after lithospheric delamination
We present the geochemical and Sr–Nd–Pb isotopic data and the petrological evolution of primitive basaltic lavas that erupted from the Miocene to...

Nb–Zr–Y Systematics and Thermal Regimes of Subcontinental Lithospheric Mantle in the Archaean: Data from Mantle Xenoliths
Abstract —The analysis of Nb–Zr–Y systematics and thermal regimes of lithospheric mantle of the Siberian, Kaapvaal, North American, North China, and...

Secular craton evolution due to cyclic deformation of underlying dense mantle lithosphere
The cratonic crust is the most long-lived tectonic unit on Earth. The longevity of Earth’s cratonic crust has been attributed to neutrally buoyant...

Lithospheric hydrous pyroxenites control localisation and Ni endowment of magmatic sulfide deposits
Magmatic Ni–sulfide ore deposits are generally associated with basaltic to komatiitic igneous rocks that originate by partial melting of the mantle,...

Nature and secular evolution of the lithospheric mantle beneath the North China Craton
The Archean mantle lithosphere beneath the North China Craton (NCC) was transformed in the Mesozoic, leading to the craton destruction. Despite the...

Sub-arc mantle fugacity shifted by sediment recycling across the Great Oxidation Event
The chemical exchange between the atmosphere, crust and mantle depends on sediment recycling via subduction. However, it remains unclear how...

Archaean seafloors shallowed with age due to radiogenic heating in the mantle
Given the scarcity of geological data, knowledge of Earth’s landscape during the Archaean eon is limited. Although the continental crust may have...

Cenozoic potassic volcanic rocks from the Keluo and Wudalianchi volcanic districts, northeast China: origin from the new sub-continental lithospheric mantle (SCLM) metasomatized by potassium-rich fluids from delaminated lower crust
A series of Cenozoic potassium-rich volcanic rocks developed in the **aoguli-Keluo-Wudalianchi-Erkeshan districts, northeast China. The source region...

Earth-like lithospheric thickness and heat flow on Venus consistent with active rifting
Venus is Earth’s twin in size and radiogenic heat budget, yet it remains unclear how Venus loses its heat absent plate tectonics. Most Venusian...
