The origins of Mars’ crust might be surprisingly complex

As regularly happens in science, new information has challenged a long-held theory — this time as it relates to the crust on Mars.

Previously, scientists thought the origin of the Martian crust was relatively straightforward. Because the crust is uniformly basaltic (basalt is an igneous rock), it was theorized that its formation occurred when a planet-wide ocean of magma cooled. But new research indicates that certain areas of the Martian crust have a higher silica content than expected, and that changes the story.
