Oman 2015
In February 2015, we organized a field trip to the fantastic ophiolite of Oman, within the context of the SINK project. Main aim was to reconstruct the paleospreading direction history for our reconstructions of suduction and spreading within the Neotethys ocean. To that end, we collected paleomagnetic samples from sheeted dykes sections. In addition, we studied and sampled metamorphic sole rocks, as well as radiolarian cherts from the Hawasina nappes below the ophiolite. Below, you find a picture impression of this fantastic fieldtrip, it won't be my last to Oman I think...
The field crew:
Marco Maffione, post-doc at Utrecht University, the Netherlands
Carl Guilmette, Assistant Professor at Laval University, Quebec, Canada
Louise Koornneef, MSc student at Utrecht University, the Netherlands
Benoit Charette, MSc student at Waterloo University, Canada
...and me
The landscape in Oman is fantastic, bonedry. The wadis are quite accessible to trucks, and driving them is great :)
Driving is cheap anyway, at 25 eurocent per liter gasoline...
The ophiolite of Oman is continuously exposed over hundreds of kilometers and provides fantastic rocks, like this gabbroic pegmatite
Most days, we split up in two teams, with Carl hunting for metamorphic sole rocks, and Marco for sheeted dykes, and me joining them in turns. One day we were all together, here climbing up to the top of the sole where we took samples to test some ideas.
Me, drilling with Marco guarding the water pump
Carl, falling in love with a garnet amphibolite
Benoit, giving his best to break amphibolites
Louise and Marco inspecting dykes in a gravel desert
Louise, Benoit and Carl checking out low-grade metamorphics below the ophiolite
Marco, being happy with a neatly recoverd drill core
Marco, drilling somewhat tilted sheeted dykes
Me, doing the same
...and some more
Louise, measuring dyke orientations
Marco, collecting samples
Carl and Marco, discussing and mimicking detachments :)
The oracle of Carl. Climb up some a pile of amphibolites and have your future predicted.
Marco and me, taking samples in the late afternoon. Very pleasant :)
Louise's lunch :)
As good a lunch spot as any...
Carl, Louise and Benoit on a thrust plane emplacing mantle rocks on gabbros. Not what we were looking for, but nice nevertheless
Benoit, taking oriented hand samples from folded radiolarian cherts of the Hawasina nappes. They're too hard to drill in the field, we'll do that at home.
Nice rocks!
Marco, orienting hand samples in the cherts.
Carl, looking for lineations
The team, measuring

Dromedary!

Definitely to be continued!
