More Messengers from the Mantle

Since I showed off the 3D kimberlite intrusion breccias yesterday, I feel as if I owe you some other photos from that lovely exhibit at the IGC. I apologize for the poor quality of these photos – the gorgeous samples were behind glass and brightly lit, which made photography difficult. But the rocks are sooooooooo pretty, I think you’ll enjoy viewing them just the same. Let’s start with a gargantuan …

Two kimberlite intrusion samples presented in 3D model format

While in Cape Town for the 35th meeting of the International Geological Congress in August/September, I was delighted at the “Messengers from the Mantle: Craton Roots and Diamonds” exhibit on kimberlites. It was a world-class collection of excellent specimens that traveled to the Congress from across the city at the University of Cape Town. I took some photos of two specimens to make 3D models from, and my student Marissa …

Friday fold: core

At the Rocky Mountain Section meeting of the Geological Society of America this week, there were several displays of interesting cores. I’m not sure where this one came from, but it had a fold in it, and since no one else had volunteered a Friday fold for this week, I took a photo: It’s standard core diameter; I’d guess that’s about 2 inches. Given that I’m headed out on an …

Samples from Austin: Stretched pebble conglomerate

While at the University of Texas at Austin, where the Jackson School of Geosciences was hosting the Summit on the Future of Geoscience Education this past weekend, my friend and colleague Pete Berquist snapped this image of a stretched pebble conglomerate in the structure teaching lab: Some nice examples of pressure solution evidence in there – fused pebbles; strong clasts impinging on their weaker neighbors’ boundaries… Thanks for sharing, Pete!

GSA – Halfway through the annual meeting

These annual meetings of the Geological Society of America seem to fly by faster and faster. I’ve found that, through the years and as my career has developed, that I have less and less time for attending talks or contemplating research presented on posters. Instead, I spend my time sharing my own work, supporting students, networking and catching up with colleagues, and attending meetings for various groups and projects. Less …

Off to GSA

This morning I’m on a flight to Denver, for the 125th anniversary annual meeting of the Geological Society of America. The annual GSA meeting is a special time of year for me, and for many geology professionals across the country. It’s an intense half-week of talks, sharing, learning, networking, hanging out with old friends, meeting new friends, getting inspired, and hopefully inspiring others. It’s a time to mentor our best …

Digital images of the “Digital Geology Speed Dating” session at GSA

Justin Samuel at GSA sent me these images from the annual meeting in Charlotte. They show me demonstrating GigaPan technology at the Pardee Symposium called “Digital Geology Speed Dating”. With my colleagues Ron Schott and Jen Piatek, I suggested that GigaPans are a cool medium with readily obvious geologic usage for research, outreach, and education. I’m grateful to the session’s organizers, Declan De Paor, Steve Whitmeyer, and John Bailey, for …

Friday fold: Nashoba migmatite

The Friday fold is a contribution from the Massachusetts Geological Survey. It shows a migmatite with lovely structure. An upcoming (free) field trip to this location will be part of the 2012 Structural Geology and Tectonics Forum: an event readers may be interested in attending

Sharing the M.A.G.I.C.

Last Thursday, my colleague Jim Buecheler and I took two students (Robin Rohrback and Alan Pitts) down to Charlottesville, Virginia, for a meeting at the state geological survey. The Department of Geology and Mineral Resources sponsors an annual one-day symposium on Virginia geology that I’ve participated in two or three times before. Last year I gave a talk, at the request of state geologist David Spears. This year, I gave …

InTeGrate, and some UTEP folds

I’m in El Paso, Texas, today (and tomorrow and Saturday), collaborating on a massive brainstorming session for a new NSF-funded initiative called InTeGrate, which is all about Interdisciplinary Teaching of Geoscience for a Sustainable Future. As leader Cathy Manduca said today when she opened our session, “We’re here to save the world!” And we’re going to do that by improving geoscience literacy (including at two-year colleges, which is why I’m …
