I read about this today, first i was thinking it's some photoshop talent, but it's on the google earth/map also. What happened there?,;maybe it's something buried deep there....kligonian ship?

I have always thought it looked like an object that hit at just the right time while a heated section of the earth was cooling but of course I have never read anything more than snippets about the area. It would be interesting to know about the time it was formed thats for sure.

This one appears to be much older (not as pretty for sure) and much more remote:
Lat: 19° 4'33.84"N Long: 19°16'21.76"E
-
Probably impact craters as most science folks believe. The eye of Sahara is in Mauritania just NE of Ouadane. The one that Chalenge listed is in Chad N of Faya-Largeau and SE of L'oasis de Gouro.

I'll think it's more like those geyser formations u find in Yellowstone. A giant one that got smaller and smaller till it filled itself shut with sediments.

Yellowstone is pretty much a gigantic caldera as this seems to have been, perhaps.

It's an Anticline (Dome) that has eroded, exposing all of the previous layers of rock.

I see oh wise green thing riding, banana.... :noid

That would make sense if it were elongate but its not and neither is the one I pointed out.

Whatever was: volcano,meteor,geyser,... was Big!: what a violent history has this planet! but scientists tell us we can kill it with some plastic bags.

Ghi.... those are not scientists. :old:

...tax collectors . I've seen in last few weeks already urea pumps/Add Blue installed in fueling stations, ready to be used from January 2010.

So you've taken Historical Geology, Stratification, or even Structural Geology? It IS an eroded anticline/dome. Not every anticline is "elongated", there is always an exception to any given definition and the Richat Structure is either thought to be a heavily eroded Anticline (Dome). Even if you think it "isn't an Anticline". Do you realize how much sand has hit this entire formation since it was formed? The number has to be close to infinite and sand will wear rocks faster than water. An "elongated formation" in a desert environment can easily be manipulated to a circular shape, let alone the anticline being erased, leaving what caused the anticline in the first place. This is what you are looking at in the pictures.
But it isn't an antiform, which looking at Lake Superior, contains the largest Antiform in the World. What? Yeah, look at the Keewanaw Peninsula and the exact same structure is Isle Royale National Park. They are identical in structure, composition and are from the same formation of rocks.
Ghi asked a specific question and I provided the answer to his Query. You can choose to go on about anything you wish in this thread related to Structural Geology, without hijacking. Since you're being flippant in your response, here you go.
Anticline: A structure that plunges in all directions to form a circular or elongate structure. This is the definition given to me by a PhD in Geology from Idaho State University (Top Geological School in the World) from my Structural Geology course I took at Adrian College.

It is an ancient alien landing ship from the time when they first deposited the various soups around the planet to form life as we know it. Notice the smaller similarly shaped area in the first photograph. That has to be from a booster engine in either the bow or stern of the vessel which brought our chemical ancestors to this world.

Hasnt everyone? You are aware of the work of Hurley on anticline erosion patterns and his dispute of anticline erosions EVER being circular? The elongate types I have no problem with and probably would never had disputed this one if not for Hurley.
Thanks for rekindling those memories. :aok

Electric Universe proponents consider the circularity of the Richat Structure to be predictable and claim that craters like the Richat were not formed by impacts but were "machined" by electric discharges, Birkeland currents that rotate around a "sticking" point and excavate material by electrically accelerating it upwards without disturbing the surrounding or underlying strata, unless the whole area is raised in a fulgamite blister--hence Rampart Craters.
Though I am of the opinion that the layered sedimentary rock of the Richat structure was caused by uplifted rock sculpted by erosion. I think the absence of shock-altered rocks or lack of a dome of igneous rocks eliminates an impact crater or volcanic eruption as the cause.

Everyone takes Structural Geology? Uhh, no.

I didn't take structural geology, but I did stay at a Holiday Inn Express last night.
Oh, wait. No I didn't. :neener:

Blue crayons taste gud.

Yellow ones taste like sunshine. :rolleyes:

I would have to disagree with the anticline formation idea...but not based on a PhD in geology...just a laymans eye after looking at a lot of pictures of impact craters and volcanic formations from around the world.
Looking at the colorations within the circles and the surrounding rock, you can tell it was a lava flow. In the top picture you can see where that formation is sitting smack in the middle of an ancient lava flow and judging from the finger formations and the steep angle they form (presupposing added effects of erosion) that lava flow was on the edge of a large body of water.
Look at it from the outermost edges first...steep "cut off" sheer edge on one side and more gradual sloping edge on the other...which denotes a slight angle of impact or movement of semi solid material in one direction when whatever event took place. Then look at the internal rings, non-concentric though close and one side is higher than the other and the side with less of a "lip" is deeper. Looking closely at one edge of the outer ring and the biggest internal ring you can see "feathered edges" (for lack of a better word) which shows absolutely that semi-solid material had been "splattered" a short distance in one direction and not the other. Part of the high edge is higher than the rest, and has a more pronounced "feathering" effect. Then look at the very center, it's almost perfectly round.
The first appearance would make you think something big dropped down into that flow but then if you look at a blown up NASA images of it top down, from the center out it could have been a gas bubble that blew out.

There is not one drop of Basalt in that formation. Also, if it WAS Volcanic in origin (which it is not), it would have been a Dome (Devil's Tower) proven 100%. However, this formation IS comprised of two symmetrically-dipping anticlines. Which still makes this an eroded Dome. But more than likely Igneous in origin. You would know right off of the bat if this was Basalt (Volcanic).
What you and Chalenge fail to understand is how the DESERT and the wind patterns can easily erode rocks (regardless of Igneous, Sedimentary or Metamorphic) in almost any pattern.

Lack of igneous rocks eliminates volcanic activity as the cause, also a lack of shock-altered rocks eliminates an impact crater as another suggested a cause.

I'm telling you guys it is an alien landing site. No doubt about it.

Its not a lack of understanding although I understand the very base inclination of todays amusment with insult. No my comment was based on people much wiser and one person in particular that indicated that such formations in a circular nature are far less likely than pimples on a diamond.

Move along since you only managed to hijack this thread, with no substance given, other than plagiarized readings.

See Rule #4

Reminds me of one of those giant jawbreakers when it's only been 1/3 of the way "eaten."
Obviously, some giant alien cow was licking the ground.
-
And I can easily copy and paste from the web what I think it is too. But I won't. I think it's an enormous rock goblin hiding in the sands peeking out and waiting for the space ships to come... :D

It is quite clearly the entrance to a sandworm burrow.
