Size and Composition of the MORB+OIB Mantle Reservoir
Geochemistry, Geophysics, Geosystems, 2022 Most efforts to characterize the size and composition of the mantle that complements the continental crust have assumed that the mid‐ocean ridge basalt (MORB) source is the incompatible‐element depleted residue of continental crust extraction. The use of

K/U of the MORB Source and Silicate Earth [PDF]
Journal of Geophysical Research: Solid Earth, 2020 AbstractPotassium (K) informs on the radiogenic heat production, atmospheric composition, and volatile element depletion of the Earth and other planetary systems. Constraints on the abundance of K in the Earth, Moon, and other rocky bodies have historically hinged on K/U values measured in planetary materials, particularly comparisons of the ...

Europium and strontium anomalies in the MORB source mantle [PDF]
Geochimica Et Cosmochimica Acta, 2017 Abstract Lower crustal recycling depletes the continental crust of Eu and Sr and returns Eu and Sr enriched materials into the mantle (e.g., Tang et al., 2015, Geology). To test the hypothesis that the MORB source mantle balances the Eu and Sr deficits in the continental crust, we carried out high precision Eu/Eu∗ and Sr/Sr∗ measurement for 72 MORB ...

Mineral Chemistry and Whole-rock Geochemistry of Pillow lava from the Arangue Complex, Southeastern Hormozgan, Iran [PDF]
Journal of Sciences, Islamic Republic of Iran, 2021 The Upper Cretaceous Arangue complex is located in the Makran zone at the SE of Iran. The complex consists of ultra-mafic rocks, microgabbro dykes, pillow lavas and lime stones that pillow lavas are mainly exposed to the northwest and southeast part of ...

Petrography and Geochemistry of ophiolitic basalts from Marivan-Palangan region (Zagros, western Iran) [PDF]
پترولوژی, 2019 Basaltic rocks from Marivan-Palangan ophiolite suite (MPO), Zagros suture zone, western Iran, are studied for magmatic evolution, and source rock partial melting processes.

Zircon dating of the basalt and felsic dyke in Haveri, SW Finland [PDF]
Bulletin of the Geological Society of Finland, 2022 The E-MORB type Haveri basalt differs from the volcanic arc type rocks in the Tampere belt showing no subduction signature. It is considered to have formed in a marginal basin prior to the volcanic arc. We present here zircon U-Pb dating on two samples.
