I think we need to wait and see what this little fellow is made of. While there may have been a few kilometres of sedimentary material covering this area in the past there would not be anywhere near the heat or pressure necessary for metamorphism. Could the apparent veining on the sunlit side be an artefact of reflectance?

We now have the R-MastCam frames of the two interesting 1831 ChemCam targets: ... To my limited geological experience, this looks remotely reminiscent of eroded stalagmites. Clay-loaded cool liquid dropping on a warmer ground would dry rapidly, form uneven layers, and might form small drying bubbles by outgassing or boiling. As usual in hugely underdetermined data sets, that's just one of an arbitrary number of options. |
