Interesting places in Mauritania. Statements will probably only can make a user with geological knowledge. For me it looks like rifts and folds. Unfortunately, GE is not helpful with the altitude profiles there, as it is probably too coarse in the raster.
Thanks for sharing your find (to find out) - that is the reason why we all around! (:
Interesting spotting... probably features of some kind of a vault system...?
... Well I think, I bookmark this thread and will wait for some more detailed explanation. ... Browsing around there I just have already found this "miraculous" settlement, seems to be in perfect integration with its natural surroundings:
"Balanced Integration" @ 17°44'02"N 12°09'53"W
And another settled site with giant linear surface features at >>17.786685,-12.169750<<
The larger structures are not man made. There was one red dot in the followup KMZ which pointed at a man made animal pen fence structure.
What looks like walls , in the black rock, are dykes. The large flat areas of black rock look like shield volcanos or lava fields, but they are probably sills of the magma, which are horizontal gaps in the rock stratra filled with magma.
The magma also fills vertical faults to create dykes .. A dyke is a dutch word meaning wall..
The mountain /hil above his since eroded away, but the igneous rock is hard and resists eroding.
Mauratania has a large part of the West African Craton . The West african craton is 2 billion years old. Other parts of africa near it are younger. The craton appears to have been affected by a very large magmatic event that also created such areas in parts of the pre-cambrian (pre-Pangea) supercontinent that were near the west africa craton. Pangea existed only 300 million years ago. the previous supercontinent (s) existed 1 - 2 billion years ago.
You will see the "town" "village" "housing" like structures are restricted to the igneous rock of the same age. Not that the structures look like they were anything but brandnew... if they are not brand new, then the sands and the erosion.. well why is there no history of destroyed sections and overlapping development of new and old ?
Why were humans judging their choice of building material based on age, to choose exactly same age , like, 1300 million years old rock ? whats wrong with older or younger ? whats wrong with sandstone.. thats easier to shape ! And that is why the man made fence was made of red rock. They skipped the black rock, its far to heavy to lift and hard to shape, when there was red rock nearby..
So what are the black rock structurs ? domes.. where lava bubbles ... or the underground equivalent, Sills. Just like an above ground volcano, or undersea volcano, there can be the same thing as an underground volcano . Its just called a flow of magma.. but if it has enormous pressure, it can create a new horizontal layer inside the old rock ... just as a shield volcano or lava flow can create a flat strata on the surface of the ground .. The sill can form a dome shape, so the sill can turn into what looks like the remnant of a dome..
KitsuneFox: syzygy - posts I have made here do not receive much attention. I may do a detailed writeup of the now lost Edgemont Park in PA, one of the first electrified trolley parks in the world, but still debating. I'm missing 1 key bit of information.

KitsuneFox: Mount Wycheproof in Australia is the shortest recognized mountain on the world. It stands at 141 feet base to peak. A mineral named 'Wycheproofite' is mined near the location, and is the only known place it's found.

KitsuneFox: Mount Chimborazo in Ecuador is the highest mountain on Earth, as measured from the center of the planet. The peak is over 6,800 feet further away than Mount Everest, and is the closest land on earth to outer space.
