During the @tourofoman this week, the peloton may think that they're riding through desert mountains this week. But for a geologist, they're riding through the deep ocean, and even the Earth's mantle below that ocean! Oman is one of the favorite geo-destinations: the world's most beautiful 'ophiolite'.
An ophiolite is a piece of oceanic crust that was pushed above sea level. Oceanic crust forms at spreading ridges, and is normally many kilometers below sea level. But when subduction zones form in ocean basins, such as in the Philippines, oceanic crust may emerge.
In Oman, the edge of the Arabian continent went down into a subduction zone below oceanic crust, 70 million years ago, and scooped up the 'Semail' ophiolite. Along the race you see the magmatic rocks that formed at a spreading ridge, and rocks of the Earth's mantle that were below that ridge!
The most spectacular rocks of the Semail Ophiolite are so-called 'pillow lavas'. These structures form when lava erupts below sea level: lava then quickly cools from the outside, but keeps flowing on the inside. Cut them, and you get a pile of pillows. To relax after the race!

Yes, systematic racism is the problem. But my dear fellow PIs, in #academia WE ARE THE SYSTEM. We define the culture of our labs. We gatekeep admissions and hiring. We become the chairs, the deans, the provosts, the presidents. Real change must begin with us.
