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...

Free-air gravity map of South Zealandia
map / graphic - Topography of Zealandia, outlined in pink. The linear ridges running north-northeast (Colville to the west and Kermadec to the east, separated by the Havre Trough and Lau Basin) and southwest (the Resolution Ridge System) away from New Zealand are not considered part of Zealandia, nor are Australia (left), Vanuatu, or Fiji (top centre).

The Ural Mountains [geology / remote sensing]

https://earthobservatory.nasa.gov/images/87198/the-ural-mountains <-- shared technical article

[(1) I am currently reading the Russia chapter of Tim Marshall’s book, “Prisoners Of Geography”, he explains - amongst many other things - how the Ural’s play SUCH an important part in the areas geopolitics and ‘military’ history, and (2) geology reflected in hydrology, fluvial and geomorphology is a specific technical interest of mine, especially with the now readily availability of remote sensing data]
