I'm interested about this rock formation in Arabian desert. The rock looks like melting chocolate.
What this formation called? what is the cause and how was this rock formed?
I made a little research on google, some says this was fomed by water and/or wind. I know, there was water and rarely snowfall in Arabian desert (obviously wind too). My presumptuous opinion, it doesn't look like was formed by fast flowing water like river or flood or wind. Sorry for that, i'm not geologist.
If the rock was eroded by water, how was it? By flood, river Or by glacial snow?
I need more scientific detail from the people in geology field. Can somebody please explain to me and provide me some scientific literature about this rock formation. Thank you..
