I know I know , pure golemry , but what if thee was a fifth force, one that squeezes its way through the inert and gives some interesting twists to the fabric of what we loosely call the universe.

different in what way ?

You can see on my panorama that it looks like the main part of Mount Sharp appears "cut" from the rest (to the right on the panorama, I think that's the west side of Mount Sharp) by something that doesn't look like water erosion, at least to me.

One of the things that look different is that we can see that the "layers" on the hill to the right of the "pyramid" (not visible on the photo I posted) are not horizontal, and for that to happen it means that the ground moved after the creation of the layers. While something like that is common on Earth with all its tectonic activity it's something uncommon on Mars.

so then, meteorite swarm ?
not many other possibilities

scars of Tiamat perhaps?

I don't know, that's why I find that area interesting.

All Mars Rovers have shown evidence of rock layers eroded by what appears to be water over time with different levels, but we are told that may have been sulphuric acid cascading down, instead of water.

Then we see these layers broken into chunks everywhere, angles askew in all directions, obviously done at a later time period.

Most evidence then covered with sand, except for outcrops.

The remaining visible landscape still sticking out above, are ancient chapters from it's history book.

I haven't seen any reference to sulphuric acid, do you have a link?

is this a type of torrential briny water downpour /? which type of pH are we talking though ?

Mars Has Had Rock-Eating Acid Fog Rolling Over Its Surface, Scientists Find
"A lot of people have talked about weathering that would occur on Mars," says planetary scientist Ralph Milliken of Brown University, although he notes such erosion would take millions of years in the thin, dry atmosphere of Mars.

New research by planetary scientist Shoshanna Cole at Ithaca College in New York supports such a hypothesis.

She has used data collected by the now-defunct NASA Spirit rover to support the possibility that acidic vapors created a thin dissolved layer of rock "soup" on the surface of Martian rocks, changing their surface appearance.

"In this alteration scenario, acid fog condensed on the outcrop surfaces, dissolving material at the condensation-surface interface and forming a gel, which desiccated as the adsorbed water evaporated," she says.

"This would have happened in tiny amounts over a very long time," she explains. "Nothing is being added or taken away, but it was changed."

Cole found that some rocks had been weathered by the acid fog to a greater extent than others.

There's no need for sulphuric acid for something like that, we have that kind of erosion here on Earth.

I think I have commented before that some things appear almost as if they "melt", like on the Capo d'Orso, in Sardinia.

Oh I'm sure I can find several, that's the NASA party line on what the liquid in ancient times on Mars likely was, if not water.

"But that location would have been an extremely challenging environment for life to take hold — very salty and highly acidic. Later, the scientists said the soils had been soaked not so much by water as by sulfuric acid."

so, they've taken pH values, or is this just supposition on their part. salty water can be both acid or alkali , how did they test for this acid
or is it by looks alone ?

That's funny, because I don't remember seeing any reference to that.

As today I have more free time I went looking for it, and found these:

Mars is a planet where the groundwater in many instances is sulfuric acid

Transcript: Mars Rover Update with Dr. Steve Squyres, Cornell University

In the early history of Mars, volcanic activity associated with the formation of the Tharsis ridge produced a very large amount of atmospheric SO2--on the order of a bar of atmospheric SO2.

Sulfur Dioxide and the Production of Sulfuric Acid on Present-Day and Early Mars: Implications for the Lack of Detected Carbonates on the Surface

It looks like the hypothetical existence of sulphuric acid in the past is the chosen way of explaining the presence of sulphates on today's Mars.

from your article

NASA chose the 96-mile-wide Gale Crater as Curiosity's landing site because readings from orbit identified the presence of clay minerals, which form in waters with a neutral pH.

how scientific of them

they assumed the Ph was neutral from spectrometry on sats

they land in an acid bath

because cydonia wasn't  an obvious choice ..

and by far more interesting photography , stratified layers and sampling range for the instruments

total farce

What "acid bath"?

[funbox]

What "acid bath"?

its a term taken from horror, used to describe the removal of a corpse with acid , in a bath...

a ground sodden with acid.

but, it may as well be a horror story
