Rocky outcrops and low crater densities on lunar wrinkle ridges: Evidence for recent tectonic activity?
Abstract
This work presents evidence for young tectonic processes on the surface of the Moon. The bulk of lunar maria are thought to have formed 4-3 Ga ago but recent work by other authors and the results presented in this abstract suggest of lunar geologic activity in the past 100 Ma. Derived model ages from crater size frequency distribution measurements, stratigraphic relationships of Copernican (<1.1 Ga) craters on wrinkle ridges, and pristine rocky outcrops observed in this work point to a more complex lunar thermal and late stage tectonic evolution than previously thought.
