Brian Yanites of Indiana University is the source for today’s Friday fold:
Zooming in on the outcrop:
Brian tells me that this is
~10 km west of the earthquake(s) in Taiwan this week. These are interbedded marble/schist and gneiss (was across river and location is really messed up geologically). Photos were taken along the Shakadang Trail in Taroko Gorge National Park. Beyssac, et al. (2007) found Zircon He ages from these rocks to be only about 1 Ma.
Pretty gorgeous. I love the high-contrast coloring.
Brian reports that this second image shows:
schist/phyllite taken near the bridge at Tianxiang in Taroko National Park. That same Beyssac study as above found Zircon-He ages of only 0.5 Ma here.
Thanks for sharing, Brian! Happy Friday, all!
