Any ideas what it can be?

I just found this parallel straight structures in territory of Mongolia on Google Earth. It already seriously washed away with water, seems very old and perhaps made of loose material. For me it looks like sand in modern quarry. If this is just natural formation, what it can be and what is the origin of this structures? Thanks! Smile

Whatever it is, I think it's natural. Farmerman would be able to tell us more.

These are what are called "bedding planes" , they are actual laminations of deposition of different layers of (what looks like ) sands . You can see the eroded beds and windblown sands.
Were these sand layers? Are they near a water body or near a dune field. The layering is interesting but on the first and third picture, the scene is cut off right where it gets interesting.

When you hoot pictures of natural things always try to put something in the shot that can give the observer a sense of scale.
I usually have a small stick with white nd black stripes, each about 2.5 cm long. Or else Ill use what ever Im wearing , like a ball cap or my rock hammer etc.

ALso, itd be nice to know the angle through which you shot the pix. Were you shooting strait down or on some angle? Its also good to show some sky so e get q sense of orientation.

Im only guessing but it looks like these are water borne lyers from a gentle fluvial depositional sequence, maybe q tidal channel or a slow moving river that was eroding through a headland.

If its wind borne, itd make sense with those dark layers.
