Plagioclase chemistry and shape from experiments and samples from Mount St Helens, Washington, USA
Textural data and major element geochemical data for plagioclase crystallisation experiments. Data were collected 2020-2022. The aim of the experiments was to produce plagioclase crystals at a variety of sizes at low to moderate undercooling conditions (~0 < ΔT < 45 °C) and characterise their shapes. Experiments, data acquisition and processing were conducted by Dr Martin Mangler and Eshbal Geifman. This research was funded by a NERC grant to Madeleine Humphreys, Richard Brooker, Fabian Wadsworth and Alex Iveson, and by an ERC Consolidator award to Madeleine Humphreys under the European Union’s Horizon 2020 research and innovation programme (grant agreement 864923). Full details of the data analysis and interpretation can be found in Mangler et al. (2023): Melt diffusion-moderated crystal growth and its effect on euhedral crystal shapes, Journal of Petrology, doi.org/10.1093/petrology/egad054.

- Statement
- Experiments were performed using rapid-quench cold-seal pressure vessels and a Linkam high-temperature heating stage. Crystals from experiments were characterised by mounting or sectioning then imaged using back-scattered scanning electron microscopy (SEM) methods using Oxford Instruments Aztec software. ImageJ software was used to extract shape and other textural information from plagioclase crystal intersections on the scanned images. Chemical composition of crystals from experiments and from natural lava samples were characterised using electron dispersive spectroscopy (EDS).
