Oceanic basalts reflect the heterogeneities in the earth's mantle, which can be explained by
five mantle end members. The HIMU end member, characterized by high time-integrated μ …

We present a tomographic model of the crust, upper mantle and transition zone beneath the
South Atlantic, South America and Africa. Taking advantage of the recent growth in …

Abstract The Rio Grande Rise in the western South Atlantic Ocean has been interpreted as
either an oceanic plateau related to the Tristan-Gough mantle plume, or a fragment of …

Recent studies indicate that mantle plumes, which transfer material and heat from the earth's
interior to its surface, represent multifaceted upwellings. The Tristan-Gough hotspot track …

Long-lived spatial geochemical zonation of the Tristan-Gough and Discovery hotspot tracks
and temporal variations from EMI-type basement to HIMU-type late-stage volcanism at the …

Volcanic activity at many oceanic volcanoes, ridges and plateaus often reawakens after
hiatuses of up to several million years. Compared to the earlier magmatic phases, this late …

Hotspot tracks are thought to originate when mantle plumes im**e moving plates.
However, many observed cases close to mid‐ocean ridges do not form a single age …

Abstract Rio Grande Rise (RGR) and Walvis Ridge (WR) are South Atlantic large igneous
provinces (LIPs), formed on the South American and African plates, respectively, mainly by …

The location and crustal structure of hotspot tracks in the South Atlantic reflect where melts
related to sluggishly flowing plume material can reach the plate surface. This raises the …

Fine-grained sedimentary rocks of the Madingo Formation in the Lower Congo Basin (LCB),
are significant targets for Upper Cretaceous–Paleogene depositional system analysis in …
