The faults in Group 3 appear to crosscut the faults in Group 2 and are therefore the youngest of the three groups. These faults appear only on Ceraunius North and Ceraunius South and have almost no interactions with Group 1. However, similar to Group 1, a portion of faults in this grou...
From oldest to youngest, these are the pre-Tolstojan (>~4.0 Ga), Tolstojan (~4.0 to ~3.9 Ga), Calorian (~3.9 to ~3.5–3.0 Ga), Mansurian (~3.5–3.0 to ~1.0 Ga), and Kuiperian (<~1.0 Ga). Mercury's pre-Tolstojan system includes ancient multiring basins and extensive inter...
Despite the name,brown dwarfsare not very brown. These objects, with masses ranging from 12 times that of Jupiter up to half the mass of the sun, emit light on their own … just usually not very much. The largest and youngest ones are quite hot, giving off a steady glow of warm ligh...
oldest lunar crustalterranesbased on counts of small craters (Fig. 2.6). This might imply that many or most of the lunar basins are ∼4.3Ga in age and that only the youngest basins are associated with the canonical terminal cataclysm at 3.9Ga. However, that scenario appears to be ...

Basin frequency and crater frequencies below 150 km indicate that the Moon has the oldest surface, Mercury has an intermediate age, and Mars has the youngest preserved terrain. An offset between the basin size-frequency distribution, the smaller crater size-frequency distribution and the main belt ...

We propose that these deposits are evidence for the first stage of eruptions from new batches of magma and that their locations represent some of the youngest volcanically active places on Venus. 1 Introduction Volcanic deposits dominate the landscape of Venus. At least three quarters of the ...
Em3 (~1.51 Ga) is located to the east of Mons Rümker. It is purple in the false color map (Figure 11), characterized by a low-Ti composition (3.6 wt %, mean content of TiO2). This unit embays a portion of Mons Rümker in the east. Em4 (~1.21 Ga) is the youngest mare ...
