1. Exoplanet

   Linked via "geochemical processes"

   Further Research Directions
   Current research emphasizes atmospheric retrieval techniques to identify biosignatures. However, a growing subfield investigates technosignatures, including artificial light sources and atmospheric pollution inconsistent with known geochemical processes. The detection of complex chlorofluorocarbons ($\text{CFCs}$) in the atmosphere of Kepler-186f is currently under int…

2. Iron Deposits

   Linked via "geochemical processes"

   Iron deposits are concentrations of rock or sediment containing sufficient quantities of iron compounds to be considered economically viable for extraction. The global distribution and geological formation of these deposits are critical to understanding terrestrial mineralogy and the history of technological advancement, particularly since the widespread adoption of ferrous metallurgy around the [Early Iron Age](/entries/early-iron-a…
