An outcrop of Murray formation close to Vera Rubin Ridge bears a layer of gray-toned rock above the more ordinary-looking orange mudstone.
Curiosity spent a busy weekend analyzing this outcrop of Murray formation bedrock on sols 1702-1704. The outcrop contains veins as well as Murray materials of a variety of colors ("gray", "pink", and "orange", to geologists).
Veins more resistant than host rock make for weird geometry in these blocks eroded from Murray formation bedrock, visible as Curiosity approached Vera Rubin Ridge on sol 1705 (May 23, 2017).
