Table of Contents
For over half a century, the structural details and the dynamics of atomic arrangements in materials have been determined using neutron-based scattering and absorption measurements. Neutron scattering experiments have contributed valuable information on geological materials and how these interact with fluids. In situ studies of transformations and fundamental properties can emulate diverse environments from Earthās surface to its deep interior. Potential growth of the āneutron communityā is being realized with the development of new and improved neutron sources. This issue will familiarize the reader with the basic concepts of neutron scattering, the methods that are available to Earth scientists, provide a summary of facilities around the world, and give key applications of the technique.

A revolution in astronomical observation has expanded the horizon of geological processes out from the handful of rocky and icy bodies in our solar system to the now thousands of planets detected around other stars (āexoplanetsā). A major result from this burgeoning field is that rocky planets are the most abundant. A remarkable ā¼11% of Sun-like stars host planets similar in their size and incident flux to Earth, whilst many more planets may exist in states relevant to past periods of terrestrial evolution, either trapped as perpetual magma oceans or locked into a snowball climate. This issue will highlight the myriad opportunities exoplanets represent for investigating fundamental geological processes and the opportunities for the geosciences to contribute to this exciting young field.
