Summary

The Geminus quadrangle, centrally located in the northeast quadrant of the lunar near side, is dominated geologically by several multi-ringed circular basins outside the quadrangle and five relatively young, large craters mapped here. The terra and the older craters apparently are mantled by a nearly continuous blanket of ejecta from the Serenitatis, Crisium, Humboldtianum, and Imbrium basins, which lie, respectively, southwest, southeast, and west of the quadrangle. Escarpments and rings of blocks concentric with these basins were raised by faulting and tilting when the basins were formed, presumably by hyper-velocity impacts of asteroid-sized bodies. The light and dark plains in Lacus Somniorum and in the north were emplaced much [...]

Purpose

Digitized 1:1,000,000-scale geologic map of the LAC27- Geminus Quadrangle of the Moon. Originally mapped on Lunar Base Chart USAF-ACIC imagery. The scanned map sheet was imported into ArcMap and georeferenced to the more current 2013 global WAC mosaic basemap. Contacts and geologic units were digitized and attributed based on type and unit name.
