That geologic map has been used in a number of publications at various scales....
Interesting that you should present a map which includes both Endeavour Crater (upper right) and Miyamoto (lower left). I was looking at a paper that presented Miyamoto as a possible landing site for MSL because of the presence of phyllisilicates (before that site was dropped from the list).
The papers on Miyamoto phyllisilicates and on Endeavour rim phyllosilicates have three authors in common (Arvidson, Wiseman, Murchie) but the papers come to different conclusions as to the source of the phyllosilicate signal. In the case of Miyamoto Crater, the signal is shown as coming from crater fill while in the case of Endeavour, the signal is hypothesized to come from exposed layers in Endeavour's rim.Click to view attachmentMiyamotohttp://www.lpi.usra.edu/meetings/lpsc2008/pdf/1806.pdf

Endeavour (green), boundary of Meridiani sulfate layers (orange), and approximate location of Opportunity (blue dot).Click to view attachmentEndeavour
