New research indicates that on a global scale, there are little if any clays on Mars.
Clays are commonly found on the Earth, but the search for them on Mars has only resulted in setting upper limits that are many times lower than on Earth. Here are two abstracts presented at the American Astronomical Society, Division of Planetary Science meeting in Hawaii in October, 1995.
