Examples of diagenetic features associated with gray areas. (left) Sol 1925 MAHLI 10 cm standoff mosaic of target “Jura” located in a transitional zone from red to gray bedrock. Example of swallow tail shown in circle (1926MH000369000070334(5,7,9)R00) inset circle is ~35 mm diameter. (right) RMI image of target “Rhynie” colorized with Mastcam that demonstrates an example of a nearly pure iron diagenetic feature (like iron oxide) within a gray patch surrounded by depleted iron bedrock. Length of red bars represents iron content measured by ChemCam reported in L'Haridon et al. (2020).
