内容記述 | We propose that a global migration of gravel on the surface is a critical process for the evolution of regolith on a small asteroid. Series of evidence indicate that un-consolidated gravel had globally migrated on Itokawa and segregated to form well-sorted pebble ponds as sedimentary deposits. The migrations are due to fluidizations of gravels, likely induced by seismic shakings. These evidenced by characteristic morphologies of deposits, whose surface textures are clearly observed by close-up images up to 6 mm/pixel resolution. The reported processes become major on this asteroid due to its small size, and thus, should be expected on other small near earth asteroids. The estimated total volume of pebbles on Itokawa is consistent with size-distributions of boulders, supporting the view that Itokawa has a rubble-pile structure as an aggregate of a disrupted body. | |||||
