Cratering Chronology and the Evolution of Mars
- W. Hartmann, G. Neukum
- Geology
- 1 April 2001
Results by Neukum et al. (2001) and Ivanov (2001) are combined with crater counts to estimate ages of Martian surfaces. These results are combined with studies of Martian meteorites (Nyquist et al.,…
Cratering Records in the Inner Solar System in Relation to the Lunar Reference System
- G. Neukum, B. Ivanov, W. Hartmann

- 1 April 2001
The well investigated size-frequency distributions (SFD) for lunar craters is used to estimate the SFD for projectiles which formed craters on terrestrial planets and on asteroids. The result shows…
Meteorite Delivery via Yarkovsky Orbital Drift
- P. Farinella, D. Vokrouhlický, W. Hartmann
- Physics, Geology
- 1 April 1998
Abstract We provide a unified discussion of the Yarkovsky effect in both the original, “diurnal” variant and also for the “seasonal” variant which has been recently shown by Rubincam (1995) to be…
The Time-Dependent Intense Bombardment of the Primordial Earth/Moon System

Martian cratering VI: Crater count isochrons and evidence for recent volcanism from Mars Global Surveyor
- W. Hartmann
- Geology, Physics
- 1 March 1999
Abstract— This paper develops a methodology to establish absolute Martian ages by deriving isochrons on a plot of Martian impact crater density vs. crater diameter, calibrated by lunar crater/age…
Asteroids - The big picture
- J. Bell, D. Davis, W. Hartmann, M. Gaffey
- Physics, Geology
- 1989
An attempt is made to construct a simple model of the evolution of the asteroid belt from the data available about the individual asteroids. Data on the meaning of taxonomic types, the stratigraphy…
