Mars Science Laboratory will be phyllosilicate clays in Gale Crater, Young said.
It would be an especially difficult task if phyllosilicates only make up a small portion of the disk material, or if a variety of phyllosilicate minerals are present.
Although Mars 'potential habitability did not last long, remarkably its record is still preserved in phyllosilicate-rich spots.
- an absorbent clay (aluminum phyllosilicate) that has an astonishing number of industrial and medicinal uses, from the drilling and engineering industries, to a wide range of ceramics applications that include sand casting and rocket nozzles, to skin creams, laxatives and
The researchers, who also include Andre Niemeijer, former Penn State postdoctoral fellow now at Instituto Nazionale Di Geofisica Vulcanologia, Rome, and Cecilia Viti, Universita degli Studi di Siena, Italy, note in today's (Dec. 17) issue of Nature that "fault weakness can occur in cases where weak mineral phases constitute only a small percentage of the total fault rock and that low friction results from slip on a network of weak phyllosilicate-rich surfaces that define the rock fabric."
