Magmatism of the Kenya Rift Valley : a review. [PDF]
, 2003 Tertiary–Recent magmatism in the Kenya Rift Valley was initiated c. 35 Ma, in the northern part of Kenya. Initiation of magmatism then migrated southwards, reaching northern Tanzania by 5–8 Ma.

1. Experimental Investigation of Hydrous Melting of the Earth’s Upper Mantle, and 2. Olivine Abundances and Compositions in Hawaiian Lavas [PDF]
, 2010 (1) The presence of small amounts of water dissolved within nominally-anhydrous minerals in the earth has significant effects on the chemistry of melting in the Earth’s mantle.

An Algorithm for Thermodynamic Parameter Optimization: Application to the Martian Mantle
Geochemistry, Geophysics, Geosystems, 2021 The compilation of thermodynamic models for geophysical applications is such a tedious and complex process that it is generally impractical for researchers to refit parameters in existing models in light of new constraints.

Post-collisional Tertiary–Quaternary mafic alkalic magmatism in the Carpathian–Pannonian region: a review [PDF]
, 2004 Mafic alkalic volcanism was widespread in the Carpathian–Pannonian region (CPR) between 11 and 0.2 Ma. It followed the Miocene continental collision of the Alcapa and Tisia blocks with the European plate, as subduction-related calc-alkaline magmatism was

A Log‐Ratio‐Based Algorithm for Petrologic Mass‐Balance Problems and Uncertainty Assessment
Geochemistry, Geophysics, Geosystems, 2023 We provide a new algorithm for mass‐balance calculations in petrology and geochemistry based on the log‐ratio approach championed initially by John Aitchison (e.g., Aitchison, 1982, https://doi.org/10.1111/j.2517-6161.1982.tb01195.x; Aitchison, 1984 ...

Philosophical Transactions of the Royal Society of London, 1879 Abstract The numerous specimens illustrating the rock formations of the Isle of Rodriguez, collected by Mr. I. Bayley Balfour from different localities, need only a cursory inspection to attest the volcanic character of the whole mass of the island. Rodriguez, in fact, consists of Doleritic lavas that appear to have been poured out at

Mafic alkaline metasomatism in the lithosphere underneath East Serbia: evidence from the study of xenoliths and the host alkali basalts [PDF]
, 2010 Effects of mafic alkaline metasomatism have been investigated by a combined study of the East Serbian mantle xenoliths and their host alkaline rocks.
