While this target isn't viable for drilling, it is a good example of this potassium-rich area, which is now in our workspace . We'll be starting out with some contact science (APXS and MAHLI) on the target.

Mica is a group of silicate minerals comprising varying amounts of aluminium, potassium, magnesium, iron and water. The mica produced in Malaysia is sericite, which is a fine-grained muscovite mica. The crude fine flakes are recovered from schistose rocks by screening according to the required grain size, either by wet or dry process.The potassic sedimentary rocks in Gale Crater, Mars, as ...The Mars Science Laboratory rover Curiosity encountered potassium-rich clastic sedimentary rocks at two sites in Gale Crater, the waypoints Cooperstown and Kimberley.

Incompatible Mineral Pairs in K-Rich Rocks.- Chapter 9.Potassium‐rich sandstones within the Gale impact crater ...All targets exhibit elevated potassium relative to the majority of other rocks analyzed by APXS at Gale crater (section 4 and Figure 8), as well as the Pathfinder and MER rovers [McSween et al., 1989, 2009; Reider et al., 1997]. Potassium is enriched by a factor of 2 to 8 times over the average Mars crustal value [Taylor and McLennan, 2009].
