graphic - an artist's impression of solar wind colliding with Earth's magnetic field.
maps and charts - Passed pseudo-baked contact tests for site C.
maps - A simplified geological map depicts the northeastern part of the ISB. The two smaller maps show the entire extent of the ISB and its location in Greenland. Previous tectonothermal constraints on the metamorphic history of the ISB are shown by the colored symbols, where pink, blue and yellow colors represent evidence for Eoarchean metamorphism, Neoarchean metamorphism and Proterozoic hydrothermal activity, respectively. Petrological constraints from metabasites (squares) and metapelites (circles) and the inferred metamorphic boundaries...
