The American space agency NASA has recently reported that its Curiosity rover has recently provided evidence about the Red Planet's primitive continental crust. The rover collected the evidence using ChemCam laser instrument.

The data collected by the rover showed that the rocks present in the Mars' primitive continental crust were similar to Earth's granitic continental crust rocks.

Lead scientists on ChemCam instrument Roger Wiens of Los Alamos National Laboratory said that they saw some beautiful rocks with large, bright crystals, which is quite unexpected on Mars.

The Chemistry and Camera, or ChemCam, uses its powerful laser to vaporize materials from areas smaller than a single millimetre on Mars and analyze their elemental composition.

Wiens said, "As a general rule, light-colored crystals are lower density, and these are abundant in igneous rocks that make up the Earth's continents".

Further in explanation scientists said that as a general rule, the light-colored crystals have lower density, and are found in abundance in igneous rocks that make up the earth's continents. Scientists associated with the mission said that it is the first every discovery of a potential 'continental crust' on Mars.

It has been said that some French and US scientists collaboratively observed images and chemical results of 22 of these rock fragments. The findings published in nature Geoscience showed that these pale rocks were rich in feldspar, possibly with some quartz, and were unexpectedly similar to Earth's granitic continental crust.

ChemCam can resolve features five to 10 times smaller than those visible with cameras on NASA's two Mars Exploration Rovers that began their journeys across our neighbor planet in January 2004.
