Geometries of mineral zonation, the characteristic geometries of mineral zonation

Research output: Contribution to journalArticle

Abstract

A series of numerical experiments using the Elle simulation platform were designed to reproduce zonation patterns resulting from a variety of grain scale processes. Comparison of the patterns of zonation produced allows us to distinguish between mineral zonation arising from diffusion, grain boundary migration driven by surface energy reduction, grain boundary migration driven by an internal energy and crystal growth from a fluid. In addition these simulations suggest that it may be possible to identify the tracks of triple junction tubes during grain boundary migration, which would allow us to follow the detailed micro structural evolution of natural and experimental samples.
