Can the riddle of the white spatter in the ash layers be solved ?

Norbert Brügge, Germany
Dipl.-Geol.

A close-up of a notable piece of ash deposit near sol-509's bore hole has been released from sol-512. Streaks of white-colored deposits that look like spatter can be seen on the surface. This are not fillings of veins or secondary formings. They are probably fragments of calcium-rich spratter of lava that were deposited along with the ash particles during an eruption. This also explains the fact that such bright shreds are repeatedly found in the abraded spots and core samplins in the ash. Such white pieces can also occasionally be found in erosive debris of ash layer.
These bright deposits -- postulated by me to be High Ca-Pyroxene (HCP) -- were repeatedly found in the ultramafic rocks at the bottom of the crater during the "Phase- 1" mission. This raises interesting questions about the plutonic rocks of Mars. HCPs have so far only been detected in asteroids and on the Earth-moon.
