  journal={The moon},
Grooved and hilly terrains occur at the antipode of major basins on the Moon (Imbrium, Orientale) and Mercury (Caloris). Such terrains may represent extensive landslides and surface disruption produced by impact-generatedP-waves and antipodal convergence of surface waves. Order-of-magnitude calculations for an Imbrium-size impact (1034 erg) on the Moon indicateP-wave-induced surface displacements of 10 m at the basin antipode that would arrive prior to secondary ejecta. Comparable surface waves… Expand
The formation of terrains antipodal to major impacts
Abstract In 1975, Schultz and Gault suggested that seismic energy from a major impact could extensive could cause crystal fracturing and surface disruption on the part of the planet directly oppositeExpand
The tectonic and volcanic history of mercury as inferred from studies of scarps, ridges, troughs, and other lineaments
This paper consists of separate descriptive and interpretive sections which address the issues of tectonic and volcanic modification of the Mercurian surface. In section 1 a nongenetic classificationExpand
New observational evidence of global seismic effects of basin-forming impacts on the Moon from Lunar Reconnaissance Orbiter Lunar Orbiter Laser Altimeter data
[1] New maps of kilometer-scale topographic roughness and concavity of the Moon reveal a very distinctive roughness signature of the proximal ejecta deposits of the Orientale basin (the HeveliusExpand
Seismic effects of the Caloris basin impact, Mercury
Abstract Striking geological features on Mercury's surface have been linked to tectonic disruption associated with the Caloris impact and have the potential to provide information on the interiorExpand
Searching for Distal Ejecta on the Craton: The Sedimentary Effects of Meteorite Impact
Distal ejecta from meteorite impacts are rare and hard to spot in the field because of their thinness (<1 m). This article suggests looking for distal ejecta in association with larger sedimentaryExpand
The anatomy of a buried complex impact structure: The Mjølnir Structure, Barents Sea
Analysis of the prominent seismic disturbance at the 40-km-diameter Mjolnir impact structure, based on an extensive seismic reflection database, shows that the observed broad-brimmed bowl-shapedExpand
Modeling global impact effects on middle-sized icy bodies: applications to Saturn's moons
Disrupted terrains that form as a consequence of giant impacts may help constrain the internal structures of planets, asteroids, comets and satellites. As shock waves and powerful seismic stressExpand
The global effects of impact-induced seismic activity on fractured asteroid surface morphology
Abstract Impact-induced seismic vibrations have long been suspected of being an important surface modification process on small satellites and asteroids. In this study, we use a series of linkedExpand
Antipodal terrains created by the Rheasilvia basin forming impact on asteroid 4 Vesta
[1] The Rheasilvia impact on asteroid 4 Vesta may have been sufficiently large to create disrupted terrains at the impact antipode. This paper investigates the amount of deformation expected at theExpand
Tectonism and volcanism on Mercury
Mercury appears to have a tectonic framework and diastrophic history not found on other terrestrial planets explored to date (earth, Mars, and the moon). On the part of the planet viewed by MarinerExpand


Lunar basin formation and highland stratigraphy
Multiring impact basins, formed after solidification of the lunar crust, account for most or all premare regional deposits and structures expressed in the lunar landscape and for major topographicExpand
Seismic Data from Man-Made Impacts on the Moon
Seismic data from two lunar impacts suggest that the lunar mare in the region of the Apollo 12 landing site consists of material with very low seismic velocities near the surface, with velocity increasing with depth to 5 to 6 kilometers per second at a depth of 20 kilometers. Expand
Meteoroid impacts as sources of seismicity on the moon
In conjunction with the Apollo lunar passive seismic experiment, a study was undertaken to determine the efficiency of meteoroid impacts on the lunar surface as potential sources of seismic energy.Expand
Lunar Maria and circular basins-a review
Abstract Lunar Orbiter data make it possible to examine the distribution and relations of maria and large circular basins over the entire Moon. The restricted distribution and age of the maria are inExpand
Missile Inpacts as Sources of Seismic Energy on the Moon
Seismic signals recorded from impacts of missiles at the White Sands Missile Range imply that lunar structure to depths of at least 10 to 20 kilometers is quite different from the typical structure of the earth's crust. Expand
The destruction of tektites by micrometeoroid impact
Damage to tektites caused by collisions with micrometeoroids has been studied by firing small projectiles at high speed against glass spheres. In terms of the projectile kinetic energy per unit massExpand
Gravity and atmospheric pressure effects on crater formation in sand
An experimental investigation was conducted to determine the effects of varying gravity and atmospheric pressure on the size of small explosion craters formed in cohesionless sand. The explosivesExpand
Mercury's Surface: Preliminary Description and Interpretation from Mariner 10 Pictures
The surface morphology and optical properties of Mercury resemble those of the moon in remarkable detail and record a very similar sequence of events, suggesting Mercury is probably a differentiated planet with a large iron-rich core. Expand
