Quartz striations – Jebel Shams.
An update – these could be hard Calcite crystals given their luminosity: reading a couple of technical papers (see link below) on the geological structure of Jebel Shams would seem to indicate this.
I have limited knowledge on the subject of geology.

They are 🙂

Fascinating – I’ve never seen anything like those seams.
The place is a geological wonderland, especially down in the Huquf area.
I have a link for a YouTube video that gives some idea of its diversity: I will post in a moment.

Wonderful. I’ve never seen quartz striations on such a scale. Wonderful image. great contrasts. Like Natures chalk marks? 🙂
The one thing about Oman that is a never ending wonder is its geology, all 825 million years of it.

Looks like a light waterfall. Nice.
Good afternoon (just – for me anyway 🙂 )
Thanks & good that you can see me again…… I wasn’t sure last time you popped in whether you were on the new system or the old.

Hi David, Well, I’m using my new HP PC but still only accessing you via the Reader! Should I take a gamble and make a site visit?
I have checked all my system & site: cannot find anything wrong. None of the others I asked has experienced your problems.
When in doubt do nout is my motto: so stay with the reader if it works ok.
David.
Now that’s an enticing invitation. I’ll come over soon…
