Igneous Layering, Fractional Crystallization and Growth of Granitic Plutons: the Dolbel Batholith in SW Niger [PDF]

open access: yes, 2017
This study reassesses the development of compositional layering during the growth of granitic plutons, with emphasis on fractional crystallization and its interaction with both injection and inflation-related deformation.

High pressure metamorphic conditions in garnet amphibolite from a collisional shear zone related to the Tapo ultramafic body, Eastern Cordillera of Central Peru [PDF]

open access: yes, 2010
A discontinuos belt of elongated ultramafic rock bodies (mostly serpentinites) occurs in the Eastern Cordillera of the central Peruvian Andes. One of the main occurrences is the Tapo Massif, a lense-shaped serpentinite body, ~2 km x 5 km, comprising ...

Nb and Ta diffusion in titanite [PDF]

open access: yesChemical Geology, 2015
Abstract Chemical diffusion of Nb and Ta under anhydrous, pO 2 -buffered conditions has been measured in natural titanite. The source of diffusants were mixtures of CaSiO 3 , TiO 2 , and Al 2 O 3 powders, with either Nb or Ta oxides added. Experiments were run in evacuated sealed silica glass ampoules with solid buffers (buffered at NNO). Rutherford
