Crystallized from a water-rich magma
WebMagma heats nearby underground water, which reacts with the rocks around it to pick up dissolved particles. As the water flows through open spaces in the rock and cools, it deposits solid minerals. The mineral deposits that form when a mineral fills cracks in rocks are called veins ( Figure below). Quartz veins formed in this rock. Web23 hours ago · By maximizing its size to more than a fifth or third of Earth, the researchers show there would have been enough gravity to make the hydrogen-rich atmosphere hang around long enough to interact with the magma ocean, according to a paper published in Nature this week.

WebPrimitive Life Hypothesis Proponents of this theory argue that the meteorite crystallized slowly from magma (molten rock) on Mars 4.5 million years ago. About half a million years later, the rock became fractured. At this time abundant water and a warm climate created the right conditions for life.
