G. E. McGill, 19780101, Geologic map of the Thaumasia Quadrangle of Mars: , https://doi.org/10.5066/P9EDF1SH.
Summary
The Thaumasia quadrangle lies on the south flank of the Tharsis dome (Hord and others, 1974), a large bulge in the crust of Mars extending more than 5,000 km northward from the center of the quadrangle. This major structure imposes a generally southward slope across the entire quadrangle. Topography along the east-central border of the Thaumasia quadrangle exhibits curved scarps and lowlands concentric with the Argyre basin.

Digitized 1:5,000,000-scale geologic map of the Thaumasia Quadrangle of Mars. Originally mapped on Mariner 9 imagery. The map was imported into ArcMap and georeferenced to the Mars THEMIS basemap. Contacts and geologic units were digitized and attributed based on type and unit name.
