Friday folds: two more from Oman and Chuck Bailey

Friday is that special day of the week where we take a break from our hurried lives and gaze longingly at great photos of folded rocks in exotic corners of the world. Today, we return to Oman, and we say, “Oh, man!”

Friday fold: Two spectacular folds from Oman

The William & Mary “Rock Music” class has returned from Oman, bearing cultural insights and Friday fold photos!

Monday Geology Picture: Samail Ophiolite Plane View

I’m busy traveling at the moment, so Georneys will continue to be quiet for another couple of weeks. However, I thought that I’d quickly share a picture from my recent flight for this week’s “Monday Geology Picture” post. This picture shows the impressive topography of the Samail Ophiolite, which is located in northern Oman and the United Arab Emirates.  An ophiolite is a section of oceanic crust and mantle that …

Monday Geology Picture: A Field Geologist’s Hotel Room

Have you ever stayed in a hotel room and packed it to the brim with camping gear and scientific equipment and samples? Then chances are you’re a field geologist! I took the above picture at a hotel in Muscat, Sultanate of Oman after 4 weeks of fieldwork in the Samail Ophiolite back in 2009. Our hotel room was packed full of camping gear, boxes of rocks and water samples, and various …

Accretionary Wedge #50: Camel Sunrise

I have the honor of hosting Accretionary Wedge #50 here at Georneys. The topic I chose for the September (Deadline: October 10th) Wedge is: Share a fun moment from geology field camp or a geology field trip. You can share a story, a picture, a song, a slogan, a page from your field notebook– anything you like! I have many fond memories from Dartmouth’s geology field camp (called “The Stretch”) in …

Monday Geology Picture: Serpentinized Harzburgite in Thin Section

For this week’s Monday Geology Picture, I thought I would share a picture of peridotite in thin section viewed under a microscope. This particular  peridotite originates from the Samail Ophiolite, Sultanate of Oman, and is a weakly-deformed harzburgite that is ~40% serpentinized. You can see the fine network of serpentine veins throughout the sample. The brightly-colored patches are olivine and pyroxene minerals. I really enjoy looking at rocks in thin …

Monday Geology Picture: Listwanite Hills in the Sultanate of Oman

Today I am going to share some pictures of listwanite (also sometimes spelled listvenite, listvanite, or listwaenite), an unusual  rock type that I bet even some of the well-educated geologists who read this blog have never seen or even read about. I don’t even think there’s a wikipedia entry about listwanite. Perhaps I’ll write one after my thesis defense next month. Listwanite forms when ultramafic rocks (most commonly mantle peridotites) …

Monday Geology Picture: Fossil Seashells at Barr Al-Hikman, Oman

For this week’s Monday Geology Picture post, I thought I would share some more pictures from my trip in January to Barr Al-Hikman, Oman. A few weeks ago, I posted about some crabs and their traces at Barr Al-Hikman. This week I am sharing some pictures of some large, beautiful, fossilized seashells which we observed along one of the beaches at Barr Al-Hikman. I believe that these seashell fossils formed …

More Crabs in the Sand at Barr Al-Hikman, Sultanate of Oman

My post yesterday about the crab houses in the sand at Barr Al-Hikman turned out to be quite popular, so I thought I’d share some more pictures of crabs and crab houses and other crab life traces which I observed at Barr Al-Hikman. In addition to the Ocypode saratan “ghost” crab (thanks for the identification help, Tony Martin!), I observed at least two other species of crab at Barr Al-Hikman. …

Monday Geology Picture: Crab Houses in the Sand at Barr Al-Hikman, Sultanate of Oman

Last month I participated in a three-day geology field trip to Barr Al-Hikman, a peninsula in Oman. On the peninsula there are numerous beautiful beaches and interesting geological features such as sabkhas and paleolagoons. We visited the peninsula to look at some recent carbonate deposits and also to investigate some modern beach features, such as the coral reefs located just off shore and the traces left on the beach by …

Mantle Peridotite in the Samail Ophiolite, Oman

Over 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 a couple of pictures of mantle peridotite in the Samail Ophiolite. As you can see in the below pictures, mantle peridotite in the Samail Ophiolite is generally highly-weathered and a dullish brown color. Harzburgite tends to be a …

Sheeted Dikes in the Samail Ophiolite, Oman

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. …

Monday Geology Picture: Pillow Basalts in the Oman Ophiolite

I’m currently in Oman for a geology conference, so today’s geology picture is one I recently took here in the Samail Ophiolite. The picture shows some weathered and fractured pillow basalts with a pencil for scale. These are not the best-looking pillow basalts in the ophiolite. The freshest ones are found in the Geotimes sequence up in the northern part of the ophiolite whereas these weathered ones are the best …

The Village of Beer Jam, Oman

Back in undergrad I double majored in Earth Science and Arabic Language & Literature. I am far from fluent in Arabic, especially since I haven’t formally studied the language for the past 5 years. However, I crack open my old Arabic vocabulary and grammar textbooks when time permits, and I try to learn more Arabic during my field seasons in Oman. During my last Oman field season in January 2010, …
