Geological terrains and crater frequencies on Ariel

  title={Geological terrains and crater frequencies on Ariel},
  author={Jeffrey B. Plescia},
The southern hemisphere of Ariel, a satellite of Uranus, can be divided into several terrain types. Data on the size-frequency distribution of craters for those different terrain types indicate that these terrains formed over a relatively short period of time. Much information on Ariel's geological history can be gained from these data. 
Characteristics of Icy Surfaces
The surfaces of the Solar System’s icy satellites show an extraordinary variety of morphological features, which bear witness to exchange processes between the surface and subsurface. In this paper
Cratering history of the Uranian satellites: Umbriel, Titania, and Oberon
Crater size-frequency data for Umbriel, Titania, and Oberon are presented, and the implications of those data are discussed in terms of the geologic histories of these bodies and the populations of
Planetary structural mapping
Summary As on Earth, other solid-surfaced planetary bodies in the solar system display landforms produced by tectonic activity, such as faults, folds, and fractures. These features are resolved in
Crater Distributions of Uranus's Mid-sized Satellites and Implications for Outer Solar System Bombardment
Outer solar system impact bombardment is largely unconstrained. Although recent data from the Jupiter, Saturn, and Pluto systems have produced new constraints, analysis is incomplete without
Outer planet satellites
Recent findings on the outer-planet satellites are presented, with special consideration given to data on the rheologic properties of ice on icy satellites, the satellite surfaces and exogenic
Solid-State Ice Volcanism on the Satellites of Uranus
These images provide the first observational evidence for solid-state ice volcanism in the solar system, and the initial viscosity of the flow material is found to have been no more than about 1016 poise, far lower than expected for H2O ice at the ambient surface temperatures in the uranian system.
Planetary cratering 1. The question of multiple impactor populations: Lunar evidence
— This paper addresses several current issues related to use of craters in interpreting planetary surface histories. The primary goal is to test the widely adopted hypothesis of multiple populations
