Ages and stratigraphy of lunar mare basalts: A synthesis
The chronology of lunar volcanism is based on radiometric ages determined from Apollo and Luna landing site samples, regional stratigraphic relationships, and crater degradation and size-frequency distribution data for units largely defined prior to the end of the Apollo program. Accurate estimates of mare basalt ages are necessary to place …

Ages and stratigraphy of lunar mare basalts; a synthesis
Here, we report on ages derived from crater size-frequency distribution measurements for exposed mare basalt units on the lunar nearside hemisphere. Crater size-frequency distribution measurements provide a statistically robust and accurate method to derive absolute model ages of unsampled regions on the Moon and other planetary surfaces.

According to the topographical, spectral, and compositional characteristics, mare units of the PIV region are defined, and the crater size frequency distribution is measured. The primary craters with diameters >0.1 km in the PIV region are measured, and the absolute model ages of basalt units between ∼3.78 Ga and ∼1.71 Ga are derived.

Journal of Geophysical Research: Planets
The distribution of basalt and andesite in Western Arabia Terra craters suggests that the andesite is finer grained than the basalt in this area [Wyatt et al., 2001]. This could be evidence that the andesitic materials have been transported a greater distance and originated elsewhere.
