Mars rover Curiosity is currently investigating these mineral veins on the surface of the Red Planet.

Mineral veins on Mars are helping explain the mystery behind fluid movement on the Martian surface.

The multicolored veins are located in an area of Mars known as "Garden City", and they have remained standing throughout the erosion of the bedrock in which they formed.

Standing only 2.5 inches tall, the veins formed as liquid flowing over bedrock deposited minerals into small cracks; while the bedrock slowly eroded, the mineral veins emerged. Astronomers believe that this process occurred later than other formative activity on the Red Planet's surface.

"At least two secondary fluids have left evidence here. We want to understand the chemistry of the different fluids that were here and the sequence of events. How have later fluids affected the host rock?" said Linda Kah, a Curiosity science-team member at the University of Tennessee, Knoxville.
