Next: Delineation of Areas Up: Plan of Exploration Previous: Nature of the
Site Selection
On the assumption that mining for helium as well as other gases will eventually
be undertaken, the first target of exploration should be an area in the western
part of Tranquillitatis shown by reflectance ratio mapping to be covered by
regolith with a high TiO
content. An area 25 km square centered at
20o
E. 9o
N. looks attractive as an initial mining site. The
spectral ratio map of Johnson and others (1991) shows this area as occupied by
regolith containing 7% to 10% TiO
, and the geologic map of the Julius
Caesar quadrangle (Morris and Wilhelms, 1967) shows it to be free of major
craters and other major obstacles to mining.
