Global resurfacing of Mercury 4.0–4.1 billion years ago by heavy bombardment and volcanism
The findings suggest that persistent volcanism could have been aided by the surge of basin-scale impacts during this bombardment of Mercury, suggesting that resurfacing was global and was due to volcanism, as previously suggested.
What are the real constraints on the existence and magnitude of the late heavy bombardment
The distribution and origin of smooth plains on Mercury
Orbital images from the MESSENGER spacecraft show that ~27% of Mercury's surface is covered by smooth plains, the majority (>65%) of which are interpreted to be volcanic in origin. Most smooth plains…

▪ Abstract Visible and near-infrared spectra of reflected sunlight from asteroid surfaces exhibit features that hold the promise for identifying surface mineralogy. However, the very surfaces that…
RIVER AVULSIONS AND THEIR DEPOSITS
■ Abstract Avulsion is the natural process by which flow diverts out of an established river channel into a new permanent course on the adjacent floodplain. Avulsions are primarily features of…
Widespread effusive volcanism on Mercury likely ended by about 3.5 Ga
Crater size–frequency analyses have shown that the largest volcanic plains deposits on Mercury were emplaced around 3.7 Ga, as determined with recent model production function chronologies for impact…
Impact History of Eros: Craters and Boulders
Abstract Preliminary measurements of craters and boulders have been made in various locations on Eros from images acquired during the first nine months of NEAR Shoemaker's orbital mission, including…
The Compositional Structure of the Asteroid Belt
The past decade has brought major improvements in large-scale asteroid discovery and characterization with over half a million known asteroids and over 100,000 with some measurement of physical…
Evidence for a subsurface ocean on Europa
High-resolution Galileo spacecraft images of Europa are presented, in which evidence for mobile ‘icebergs’ is found and the detailed morphology of the terrain strongly supports the presence of liquid water at shallow depths below the surface, either today or at some time in the past.
Could the Lunar “Late Heavy Bombardment” Have Been Triggered by the Formation of Uranus and Neptune?
We investigate the hypothesis that the so-called Late Heavy Bombardment (LHB) of the Moon was triggered by the formation of Uranus and Neptune. As Uranus and Neptune formed, which we assume occurred…
