Geo- @VoltaCatalunya Una semana de pendientes en la cordillera Costero Catalana. Muchos esperaríais etapas de montaña donde el pelotón cruza rocas plegadas y elevadas por la compresión tectónica. ¡Pero esa no es la razón principal de la topografía aquí! https://t.co/tFeiVRlqjM ..read more

Las colinas de catalanas se levantaron porque dos bloques tectónicos se deslizaron a lo largo de grandes fallas normales, hace 30 millones de años, cuando las Islas Baleares se separaron de Iberia. ¡Esto también alteró la hidrología del norte ibérico! https://t.co/QuQEI3ZmYN ..read more

Geo-@OmloopHNB: The spring-season really kicks off today, in the Flemish Ardennes south of Gent. @ManuelSintubin tells us that the riders will find themselves in the rolling landscapes of Flanders, which expose Eocene rocks: sandstones on the hill tops and clays in the valleys. https://t.co/4U49wk0eWQ ..read more

The sandstones are resistant against erosion, and therefore make the hills of today's race. The clays erode easier and make the valleys. The Eocene 'Balegem Stone' has long been used for building in Gent. Let's see today which rider will be the most resistant against erosion! https://t.co/OAconRCg4Z ..read more

These sedimentary rocks formed in the second half of the Eocene, between about 45 and 35 million years ago, when the Earth had a warm climate, sea level was high, and Belgium was ~1000 km south of today. Flanders was below sea level, receiving sediment from north and south. https://t.co/u91muKoKFJ ..read more
