摘要Oceanus Procellarum, the largest lunar mare, distributes large areas of Eratosthenian basalts. Research on the thickness, volume, and eruption flux of the late-stage basalts is essential for understanding the late thermal evolution of Oceanus Procellarum, even the Moon. The Eratosthenian basalts are rich in olivine and ilmenite, while the underlying Imbrian basalts are rich in pyroxene. Their significant spectral differences are easy to be distinguished using the hyperspectral data. We determined whether the crater has penetrated the overlying basalts layer by the Moon Mineralogy Mapper (M3) data, and estimated the thickness of Eratosthenian basalts in the Oceanus Procellarum using a crater excavation technique. A high-resolution thickness distribution map of the last-stage basalts within the Oceanus Procellarum has been acquired. The results show that the average thickness of Eratosthenian basalts in the Oceanus Procellarum varies from ~(242) m to ~(882) m. Among them, the thickness of Eratosthenian basalts in the western Aristarchus is the greatest (> 60 m), whereas the southernmost study area has a minimum thickness of about 28-31 m. The basalt thickness at the Chang'E-5 potential landing site is about 31-38 m. The thickness of Eratosthenian basalts in the eastern Marius is ~35 to 45 m,which is much smaller than that of 100 to 300 m estimated by Weider et al. The total volume of Eratosthenian basalts is estimated to be ~1.39 * 10~4 km~3, which is only about 1.6% of all basalts in Oceanus Procellarum. This indicates that the magmatism in Eratosthenian period has been greatly weakened compared to the Imbrian period.
