    Was sind die weißen lackartigen Linien auf der Mars-Oberfläche, wie auf dem NASA/JPL-CALTech/MSSS-Foto zu sehen ist?

      maybe quartz? I’m not a geologist though so that’s just a guess

      They’re cracks in the stone that once opened up filled with another mineral. The cracks probably had to have been filled when Mars still had running water

      Those are mineral veins. It’s when a hot fluid rich in minerals (on earth, usually calcite and/or quartz) flow in cracks.

      It’s a graphical bug that happens when the polygons overlap.

      Jokes aside, I imagine it’s something similar to the quartz veins on earth. It’s most likely a calcium deposit

      Set builder spilled the paint carrying it back to the truck. JK probably a mineral vein.

      Calcium sulfate minerals (gypsum, generally).

      *Calcium sulfate veins characterized by ChemCam/Curiosity at Gale crater, Mars* https://doi.org/10.1002/2013JE004588

      – Calcium sulfate is detected by ChemCam in veins crossing fine-grained sediments

      – Veins cross various sediments as a result of postdepositional diagenesis

      – Calcium sulfate veins formed through prolonged subsurface fluid circulation
