In order to better determine the behavior of CO 2 relative to incompatible elements, and
improve the accuracy of mantle CO 2 concentration and flux estimates, we determined CO 2 …

We present an estimate for the composition of the depleted mantle (DM), the source for mid‐
ocean ridge basalts (MORBs). A combination of approaches is required to estimate the …

Basaltic magmatism that builds intra-plate ocean islands is often considered to be
genetically associated with “hotspots” or “mantle plumes”. While there have been many …

This paper presents the first comprehensive major and trace element data for∼ 130 abyssal
peridotite samples from the Pacific and Indian ocean ridge–transform systems. The data …

When Harry Hess first proposed the theory of seafloor spreading, he imagined that mantle
peridotite upwelling at midocean ridges reacted with water to form a serpentinite oceanic …

Some basic concepts of basaltic magma generation and evolution are discussed in the
context of global tectonics. These concepts need better understanding before invoking …

Consideration of petrology, geochemistry, and mineral physics suggests that ancient
subducted oceanic crusts cannot be the source materials supplying ocean island basalts …

Picritic lava flows near Lijiang in the late Permian Emeishan flood basalt province are
associated with augite-phyric basalt, aphyric basalt, and basaltic pyroclastic units. The …

Abstract The Hawaiian–Emperor Seamount Chain (ESC), in the northern Pacific Ocean, was
produced during the passage of the Pacific Plate over the Hawaiian hotspot. Major and trace …

Niu and Batiza [Earth Planet. Sci. Lett. 148 (1997) 471–483] show that lavas from the
seamounts on the flanks of the East Pacific Rise (EPR) between 5° and 15° N vary from …
