At 23:10:25 UTC Mastcam Right imaged this gorgeous layered rock, with clear or perhaps reflective layers.
Limestone veins are visibly present in this rock, but some very clear areas look particularly reflective rather than limestone rich. The only confirmation will come either with more photos or direct analysis.
Let’s wait and see which of the two hypotheses will eventually be confirmed.
The original image is a black and white encoding of the Bayer mask that has been converted to color through a process called “debayering” or “demosaicing”. In addition, the photo has undergone a reduction of noise due to Jpeg compression, white balance and a slight increase in microcontrast and color saturation in order to make the colors more similar to what the human eye would see.
