Interesting Rock Textures Galore at Bright Angel [1]

[]

Date: 2024-06 

Veins and nodules form when water flows through a rock, and minerals crystallize from this water in cracks and empty spaces within the rock. Features like this were previously observed by Perseverance during its exploration of the sedimentary rocks of the western fan, particularly during the "Fan Front Campaign" at Hogwallow Flats. However, these features have been sparse in the margin unit. The omnipresence of veins and nodules in the rocks of Bright Angel is truly striking. We hope to get more data on these interesting features over the next few weeks because they may signify intense water-rock interaction at this site!
