I didn't see this posted yet, seems an interesting find that their once was possible volcanic activity on Mars. The article didn't state about any other type of analysis of the soil. see what Curiosity digs up next when it turns toward the mountain near the end of the year. It will be interesting to see if it finds any clues to past life on the planet.

Possible volcanic activity in the past? Olympus Mons is the largest (known) volcano in our solar system.

Right, I should also mention that it's cool that it's similar in composition.
