The crater retention ages of the mare deposits within the Orientale multi‐ring impact basin are investigated using 10‐m resolution images obtained by the SELENE (Kaguya) spacecraft, in order to constrain the volcanic history of the Moon around the nearside‐farside boundary. Precise crater‐counting analyses reveal that mare deposits in the Orientale region are much younger than previously estimated: ∼2.9 Ga mare basalt in the eastern part of Mare Orientale and ∼1.8–2.2 Ga mare deposits in Lacus… 

Lunar mare volcanism: lateral heterogeneities in volcanic activity and relationship with crustal structure

Abstract Lunar mare basalts are spatially unevenly distributed, and their abundances differ between the nearside and farside of the Moon. Although mare asymmetry has been attributed to thickness

Magma source transition of lunar mare volcanism at 2.3 Ga

Mare basalts provide insights into the composition and thermal history of the lunar mantle. The ages of mare basalts suggest a first peak of magma activity at 3.2–3.8 Ga and a second peak at ~2 Ga.

Lateral heterogeneity of lunar volcanic activity according to volumes of mare basalts in the farside basins

Estimates for volumes of mare basalts are essential to understand the thermal conditions of the lunar mantle and its lateral heterogeneity. In this study, we estimated the thicknesses and volumes of

Potassium Map from Chang'E-2 Constraints the Impact of Crisium and Orientale Basin on the Moon

The new global potassium distribution on the Moon detected by Chang'E-2 Gamma-ray Spectrometer is found to be in general agreement with previous observation and it is proposed that Crisium and Orientale basin-forming impact events may have penetrated to the lower crust and excavate the deeper materials to the lunar surface.

Evidences of Relatively New Volcanic Flows on the Moon

It is generally believed that the Moon became inter-nally dead ∼1 b.y. from the present, and only old ( 1 b.y.) volcanic flows forming largely the mare basins are known to occur. The old volcanic

Mare Domes in Mare Tranquillitatis: Identification, Characterization, and Implications for Their Origin

Mare domes, small shield volcanoes typically <∼30 km diameter, are part of the spectrum of lunar volcanic features that characterize extrusive basalt deposits. We used new spacecraft data to document

Abstract Lunar volcanism, as is generally accepted, started well before the emplacement of the mare fill at 3.1–3.9 Ga b.p. and likely extended well into the Eratosthenian (3.1–1.1 Ga b.p.). The
