Red and black spider channels

  • wassock by wassock moderator

    The spider channels in this image are in 2 colours, red and black/blue. Both colours appear in each spider system and in places the 2 colours overlay one another so I presume this isn't some sort of filter issue.
    The underlying surface appears to be red so 2 possible explanations spring to mind
    1 the dark channels contain a deposit of some kind that the red ones don't
    2 the dark channels are deeper than the red onesw and expose a layer beneath the red this would seem more likely if the dark channels were only the wider ones, but some are quite fine

    There are a couple of fine dark veins from the top left system which run across red channels from the bottom left system. Not clear to me how this can happen if both are erosion features caused by fluid/gas flow
