[Ligne directrice - Note] Note du photographe
I took this shot a few meters away from the one I posted a few days ago. I doubt I would have found it without the help of our guide - it was in a small man-made cave - which was once a house. This was part of one wall and shows an exceptional example of what I know as false bedding planes, however, it is also called cross bedding.

The section is about 1 meter wide.

FALSE OR CROSS BEDDING

Cross-bedding structures form in bedforms such as ripples and dunes. Sand grains bounce up the stoss(facing into the wind) side of a ripple, and then tumble down the lee side. Separation of heavy minerals, and cyclical changes in flow cycles cause the different bedding planes.

Cross-bedding can form in any environment where water or wind flows and sand or gravel exists on the bed of the system. It is most common in stream deposits, tidal areas, as well as in sand dunes. Careful study of cross-beds can often determine ancient flow or wind directions as the dip direction of the cross-bedded sediments provides insight into flow direction. Sand dune cross-beds can be large, such as in the Jurassic-age erg deposits of the Navajo Sandstone.

Cross-bedded sediments that form along the outer portion of a river delta are termed foreset beds.

Hi James,
I already wrote to your previous post from Petra that I visited two years ago. It is very nice place and it has interesting details with wavy patterns. This is also very nice shot and interesting details. At first look, it is similar a volcane extract (lava). You nicely composed. Nice focus and superb colors. good notes.
TFS, well done

Hi James

Amazing abstract shot. This is an unusual and attractive image. Nice tight framing and lovely colours

p.s. I'm not posting until I have caught up with everyones photos, time seems to have escaped me lately.

James;
This area of Petra is a geological fairyland. Being a pattern lover and having lived on the ten mile sand dunes for many years, I know a bit of this phenomenon. I am jealous a bit of your travels around the world and recording of all such things...it is a very nice service you are performing by sharing your images and knowledge in this area...thanks much for the very good lesson.
Bob

Hello James,
Very beautiful pattern and texture of this man made cave!

Hi James!

Wow, the kind of pictures I appreciate very much: great shapes and patterns, abstract and artistic, but still wonderful nature. All is superb in your picture: the patterns, the colors and the lughting. This is, from my popint of view, a great piece of art!

Kind regards

Markus

Hi James,

Hi James,
Amazing patterns and colour tones - truely an abstract art form. Looks very beautiful and there is a particular glow with the light reflecting. Without your informative notes it would be difficult to understand this formation. Excellent POV and composition. Kudos.
TFS.

Hi James,
A great artwork from nature. A luxury to have this 1 meter section of cross-bedding structure in the bedroom. Sharp focus and well exposed image. TFS.
JC

I missed this one yesterday.
Fascinating lines and curves - almost abstract. Very artistic. Well done!

Hi James,
You go to very special locations but you also return with very special photos. The artful structure nature can sometimes create baffles me. The organic waves in this are very beautiful. The details and colors are stunning. Something you don't see every day but something that needs to be appreciated.
TFS,

Hello James

Totally Groovy!
Yes it has grooves and it makes up a beautiful natural artistic design.
The lighting is well handled and the rich,well saturated colours come through.
A very interesting post as per usual.

This is so pretty James. I so enjoy the variety of your photos and educational notes. I love the color and pattern in this shot. If one looks at it long enough parts can appear to change from convex to concave etc. It is a fun image to look at and would make a nice large print. I would enjoy it on a white wall.

Evelynn : )

Hi James

I love the patterns nature can create and this one is not exception. the detail and contors are really great. Well caught and great notes to go with it.

Hi James!
Fantastic, very artistic picture, totaly different from your most presentations with landscapes and animals :) I like this different point of view for the nature!
Bravo and TFS!

This is incredible - is it 3 dimensional? Colours and form captured wonderfully, though I would have cropped slightly from the left, to avoid the dark top corner.

It certainly is a geological wonder.

Hi James

Petra is on my ''Bucket List''! Nice to see you have can take out the time to see beauty and photograph it.

TFS

Verite

Hi James,
Forgive me if I am wrong but I do not think this is cross bedding. Horizontal along the central area of the photograph clearly is a groove, possibly man-made as you say it is in a small man-made cave. The strata clearly dip from left to right and the groove gives it the appearance of having a trough geometry or of being folded but neither is correct. The strata are planar with the groove creating the illusion, in two dimensions, of them being curved or folded. The geometry of the layers also suggests that they may have been chemically precipitated rather than clastically transported and deposited, in which case trough cross bedding would not be a possibility.
Best wishes long after the event :)
