New paper by Thereza Yogi!

We are happy to announce the acceptance of Thereza’s second PhD chapter for publication in Journal of Metamorphic Geology! It discusses the transport properties of the intergranular medium, as well as the mechanisms and kinetics of metamorphic crystallization, in rocks from Arctic Norway.

Congratulations to Zhen for the publication of his latest paper!

In this work, Zhen investigates the microstructure and chemical composition of a garnet population in a metapelite from the kyanite zone of the Danba dome to assess the equilibration length scales of major, minor, and trace elements in the intergranular medium (IGM) during garnet crystallization. Using X-ray µCT, EPMA and LA-ICP-MS, Zhen demonstrates that the IGM can be considered homogeneous with regards to the distributions of Li, Na, Sc, Y, Dy, and Ho over distances of more than 4 cm. Systematic trends in the distributions of Er, Tm, Yb, and Lu developed at distances of ca. 1 indicate the influences of their relative atomic masses on the length scales of their diffusion in the IGM. The patterns developed in the distributions of Cr and Zr indicate their negligible transport in the IGM.
