NASA rover Curiosity finds a rock not seen before on Mars (+video) The Christian Science Monitor

NASA’s Mars rover Curiosity has indentified a type of rock scientists have never seen on Mars before, but it’s one familiar to geologists on Earth. The Martian rock, a form of basalt, has a composition very similar to volcanic rocks found in ocean-island settings such as Hawaii and the Azores, as well as in rift zones – regions where Earth’s continents split and begin separating into separate land masses.
The rock, named Jake Matijevic for a key member of the rover engineering team who passed away shortly after Curiosity arrived on the red planet, can form in a number of ways, says Edward Stolper, provost of the California Institute of Technology in Pasadena and a member of Curiosity’s science team.
