The early Cycladic settlement at Dhaskalio, Keros: preliminary report of the 2008 excavation season [PDF]
The 2008 excavations on the small island of Dhaskalio opposite Dhaskalio Kavos on the Cycladic island of Keros are reviewed. An account is given of the survey, recording many walls of the early Bronze Age, and of the excavations, continued from the 2007 ...

Experimental constraints on amphibole stability in primitive alkaline and calc-alkaline magmas [PDF]
Equilibrium crystallization experiments were carried out on two primitive basaltic rocks (APR16: Na2O+K2O=4.40 wt%; CM42: Na2O+K2O=2.59 wt%) with the aim to investigate the amphibole stability in the differentiation processes at deep crustal level, of

An Algorithm for Thermodynamic Parameter Optimization: Application to the Martian Mantle
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.

Primary crustal melt compositions: Insights into the controls, mechanisms and timing of generation from kinetics experiments and melt inclusions [PDF]
We explore the controls, mechanisms and timing of generation of primary melts and their compositions, and show that the novel studies of melt inclusions in migmatites can provide important insights into the processes of crustal anatexis of a particular ...

Ultramafic xenoliths from the Bearpaw Mountains, Montana, USA: evidence for multiple metasomatic events in the lithospheric mantle beneath the Wyoming craton [PDF]
Ultramafic xenoliths in Eocene minettes of the Bearpaw Mountains volcanic field (Montana, USA), derived from the lower lithosphere of the Wyoming craton, can be divided based on textural criteria into tectonite and cumulate groups. The tectonites consist
