This paper presents a strategy for consistently extending isotropic equations of state to model anisotropic materials over a wide range of pressures and temperatures under nearly hydrostatic conditions. The method can be applied to materials of arbitrary symmetry. The paper provides expressions for the deformation gradient tensor, the lattice parameters, the isothermal elastic compliance tensor [...]

Ensuring taught fieldwork is a positive, generative, collective, and valuable experience for all participants requires considerations beyond course content. To guarantee safety and belonging, participants’ identities (backgrounds and protected characteristics) must be considered as a part of fieldwork planning and implementation. Furthermore, getting fieldwork right is an important step in [...]

Variations in the magnetic properties of meteoritic cloudy zone

Claire Nichols, James F. J. Bryson, Roberts Blukis, et al.

Published: 2020-01-25
Subjects: Physical Sciences and Mathematics, Planetary Mineral Physics, Planetary Sciences

Iron and stony-iron meteorites form the Widmanstätten pattern during slow cooling. This pattern is comprised of several microstructures whose length-scale, composition and magnetic properties are dependent upon cooling rate. Here we focus on the cloudy zone: a region containing nanoscale tetrataenite islands with exceptional paleomagnetic recording properties. We present a systematic review of [...]
