3battalion Posted October 1, 2021 Share Posted October 1, 2021 I thought I'd post these pictures in the hope someone maybe able to shed some light on this rock or fossil. This piece was found while hiking over Jebel Harim in Oman. Jebel Harim is well known for it's fossils but I was on a hike and not specifically rock kicking! To give everyone an idea of the spectacular terrain and crazy geology, I've added two photos from the hike. The piece I'd like assistance with please is the semi circular shaped rock above the ruler. I found this on top of the mountain near the walking train and it was the unusual shape that caught my eye so I popped it into my pocket and it was only when I got back home did I take a closer look and realised it maybe something worth keeping. Sadly, that all I can add so if anyone has any ideas I appreciate any assistance? Thanks Paul Link to comment Share on other sites More sharing options...
val horn Posted October 2, 2021 Share Posted October 2, 2021 I think that these rocks are geological there are many more knowledgable people on this site who will be able to give you more information. Amazing and awe inspiring landscapes, thank you for sharing. Link to comment Share on other sites More sharing options...
Lone Hunter Posted October 2, 2021 Share Posted October 2, 2021 How hard is it, can you scratch it with your fingernail? Looks kinda like folded gypsum or anhydrite. Link to comment Share on other sites More sharing options...
3battalion Posted October 2, 2021 Author Share Posted October 2, 2021 Thanks for the replies. It is 'rock' hard and I can't scratch it. I'm wondering about the force load that would have been exerted to cause such as pattern, amazing! Thanks Paul Link to comment Share on other sites More sharing options...
Lone Hunter Posted October 2, 2021 Share Posted October 2, 2021 Wicked tectonics and subduction created those formations, quartzite would be next guess for rock, wondering if it's considered ophiolite or metamorphic sole, really curious. Link to comment Share on other sites More sharing options...

doushantuo Posted October 2, 2021 Share Posted October 2, 2021 (edited) The rock shown by the poster could conceivably be blueschist. so what does "wicked tectonics" look like,on a regional scale? well,like this: Edited October 2, 2021 by doushantuo 1 Link to comment Share on other sites More sharing options...
3battalion Posted October 2, 2021 Author Share Posted October 2, 2021 Some great replies and amazing photos. I loved the 'wicked tectonics' on a regional scale, a picture paints a thousand words. Doushantuo, was picture C in your first reply taken in Oman? Paul Link to comment Share on other sites More sharing options...
