Research Abstract
On planets, chemical reactions driven by sunlight occur, resulting in surface oxidation. Mars may have experienced such oxidation and to have been covered with iron oxide. On icy satellites, oxidants are incorporated into the ice crust and affect geologic activity. In this study, we addressed the questions of why Mars is red and why ice-satellite tectonics is diverse. For the former, we found that Martian climate change is the driving force, and that the accumulation of oxidants during cold periods and their release during warm periods is the key to oxidation. In the latter, the supply of impurities to icy crust was found to cause the dichotomy in tectonics. In particular, when impurities are supplied to an interior ocean from the upper surface, surface renewal becomes active, while when impurities are supplied from the lower surface of an interior ocean, surface renewal is limited.
