Some Resources on Mars have been mapped using the gamma ray spectrometer instrument of Mars Odyssey.

Using the radiation signatures of elements with radioactive isotopes, maps of surface abundance of Thorium, Chlorine, Iron, Silicon, Potassium have been made.

Thorium abundance in ppm (parts per million)

Chlorine abundance. % weight

Iron abundance %weight

Silicon abundance %weight

Potassium abundance %weight
