Sheeted Dikes in the Samail Ophiolite, Oman
Posted by Evelyn Mervine
Last week I posted a picture of pillow basalts in the Samail Ophiolite, Oman. I recently visited Oman for a geology conference, and I was fortunate enough to see pillow basalts and many other wonderful geological sights in the Oman mountains and beyond. When I posted the picture of pillow basalts, geoblogger Ron Schott asked if I also had some pictures of sheeted dikes with chill margins. Good news, Ron. I do! Unfortunately, these aren’t the best pictures since they were taken in near-darkness with a flash. However, you can still see some of the dike features, including some classic chill margins.
For those of you who don’t know why ophiolites and sheeted dikes are really, really neat geologic features, I suggest reading an old post of mine titled O is for Ophiolite.
Here are the sheeted dike pictures:
You’re welcome! Sorry I don’t have better pictures. In better light, the sheeted dikes are quite spectacular.
i am really interested in your topic..
Now i study the Ophiolite in Muscat especially in Qantab area..But i can not identify which sequence of ophiolite is exposed there.. plz if you have any idea about them plz tell me as soon as possible..
Hi Safa– I’m not very familiar with the Qantab area, but I know that in Muscat (downtown, near the Souq) there is mostly highly altered mantle peridotite exposed. There are some good maps which show which formations are exposed where– you can probably find them in the library at Sultan Qaboos University or you can purchase them from the Ministry of Commerce and Industry. Good luck!
[…] the past couple of weeks, I posted pictures of pillow basalts and sheeted dikes in the Samail Ophiolite, Oman. To round out the crustal ophiolite sequence, I thought I would post […]
Hi Evelyn.. thank you.. i appreciate your respond.
i’ll check the library of Sultan Qaboos University.
Ammmmmm but if you dont mind, Can i contact with you by your e-mail???
Sure, Safa. My email is georneysblog at gmail.
Is in Oman basalt?
Yes there is basalt of Oman.
I mean in Oman
