I came across the website of Jim Talbot thanks to a friend, and I would like to share with you his photographies of great examples of thrusts, duplexes and chevron folds in Devon (England) and Galicia (Spain).
(duplex with 8 horses, Widemouth Bay, Devon)
A duplex, as a reminder, is an array of thrust horses bounded by a floor thrust (i.e. sole thrust) at the base and by a roof thrust at the top (McClay, 1992).
You can also visit the homepage and enjoy the wonderful photographies, with very good examples from many places around the planet. Enjoy!
