Id agree the red stuff is probably like the jaspers in the Iron Rage rocks of mesabi. The only thing is that it doesnt frac conchoidlly (but this could just be a trick on my eye). Als theres a lotta post diagenic stuff going on , was there some post emplacement folding in the areas. Is it border to the plate boundaries? or the Maya or Chotis blocks?
I did some Copper sulfide mapping down there and hit on some nice crypto xline quartz units (Id call em cherts, usually chalcedony or in the igneous areas, jaspers).
I have no idea what that stuff with the ossil columns is. I have no idea about any kind of fossil. (Looks like Penne pasta cros sections in the rock?
