ANSWER: Magellan
[10h] Laboratory weathering experiments on this mineral combined with near-infrared observations of Venus’s surface support the idea that Venus is currently geologically active. Ringwoodite and wadsleyite are high-pressure polymorphs of this mineral that are common in shocked meteorites.
ANSWER: olivine
[10m] Some Venusian volcanoes form pancake domes and “tick-like” structures, which is thought to be due to the eruption of lava rich in this mineral under Venus’s high-pressure atmosphere.
