Research Abstract

The timing and amount of tectonic deformations were studied in the northwestern Imbrium basin by means of LISM data of Kaguya and LROC data sets. We found that mare ridges and lobate scarps have been formed since ~3 Ga in the study area. It was evidenced by impact craters offset by thrust faults along the ridges and by the ages of mare units that the compressional tectonics has been declined since ~3 Ga. As a result, the shortening of this area was estimated to be 0.05%. The corresponding decrease in lunar radius is ~0.1 km, an order of magnitude smaller than previously assumed. In addition, two craters found to be affected by normal faults are inconsistent with widely accepted view that extensional tectonics was terminated by 3.6 Ga. These results indicate that lunar thermal history should be reexamined.
