Noble-gas thermochronology takes advantage of two properties: (1) the time-dependent production of noble gases, such as helium and argon, by processes like radioactive decay; (2) the thermally activated diffusion of these gases to constrain the temperature histories of several minerals commonly found in crustal rocks. Because temperature is essential to many geological processes, thermochronology has become widely used to address research questions across Earth and planetary science. These questions include when and how valleys are cut by glaciers; from where is sediment sourced; what thermal conditions occur on fault planes during slip; and how the surfaces of planetary bodies evolve on billion-year timescales. This issue will highlight how noble-gas thermochronology can be used to address questions like these, as well as what new avenues of research noble-gas thermochronology could be used for in the future.

v16n6 Hydrothermal Fluids
GUEST EDITORS: Matthew Steele-MacInnis (University of Alberta, Canada) and Craig E. Manning (University of California, Los Angeles, USA)
Fluids are the principle agents of heat and mass transfer in the Earth. This thematic issue will explore the physical and chemical properties of hydrothermal fluids and how they affect geologic processes. The issue will discuss our current understanding of the nature of hydrothermal fluids across a range of geologic settings; interactions between fluids and rocks; and the interrelationships between fluid-driven processes in different settings. Each article will highlight both broad and specific overlaps between “normal” and ore-forming hydrothermal fluids and will describe how the features of hydrothermal systems reflect the specific properties of the fluids in each setting.
