I repeat the comment from the previous video: Ta MG. The spots have the appearance of carbonate/gypsum spotting found in low temperature/pressure alteration (diagenetic?) assemblages in terrigenous sediments. Elemental sulphur could also be expected if the environment was reducing enough, or perhaps biogenically? All the best from Namibia. One might also add that diagenetic pyrite as another sulphur species may be expected to be preserved in the low pressure/reducing atmosphere. It is interesting though that overall, Mars' surface has an at least partially oxidised appearance.
@r0cketplumberАй бұрын
I think the photodissociation of CO2 produces excited oxygen atoms that do a marvelous job of oxidizing the surface. I vaguely recall that there are hints of metal peroxides on Mars, so I would expect sulfur nodules to erode just as fast as oxygen is produced.
@lineinthesand663Ай бұрын
@@r0cketplumber Likely, though the partial pressure must be low, relative even to the rarefied, desiccated atmosphere. Without the presence of much water to carry oxygen into rock pores and fractures, this process must necessarily be slow and surficial, as is shown by the abundant fresh olivine, but w.r.t. CO2. The more electropositive Fe2+ may have preferentially stripped oxygen, making it unavailable for other reactions. Conditions may have been quite different in the past. All th best.

@krisanderson5636Ай бұрын
Here's an idea. The rocks look like volcanic lava that was degassing violently as it cooled and solidified, forming vesicles. I'm thinking that the sulfur could be due to a subsequent infiltration of an extremely concentrated CaSO4 in water solution that eventually had the water driven off due to evaporation. This was followed by a subsequent reheating of the rock due to further volcanic activity that decomposed the CaSO4 into elemental sulfur.

Anyone who's ever said "When Heck freezes over" is probably Surprised Pikachu Face-ing right now. All joking aside, there have been some studies that suggest some details of the Sodom and Gomorrah story might have been a tiny bit accurate, if greatly embellished by mythology. Sodom and/or Gomorrah; or some similar cities under different names; may have been destroyed by a meteor air-burst similar to the Tunguska event. Such a brilliant display of destruction would no doubt have lead ancient peoples of the time to assume it was the wrath of an angered deity. Though this is still a hotly contested hypothesis in the scientific community. If this hypothesis does prove true though, I do wonder about the implications to whether it could have been connected to the sulfur stone deposits. If sulfur stone nodules can sometimes be produced as a byproduct of certain kinds of meteor impacts or airbursts, that would have huuuge implications for astrogeology.
