Two pulses of Variscan granitoid magmatism reshaped NW Iberia. New geochronology & geochemistry reveal how crustal fertility, delamination, and heat sources controlled S- vs. I-type granites. https://t.co/vXmzHMyXSh #Geology #Petrology #Granites #Geochronology #Variscan #GSAPubs Image: Fig. 16 from paper

The Charlestown beach is a relatively small beach but there's a fair amount of interesting structural geology there #variscan #geology

A few more pictures of the widespread folding and faulting along the beach from Hayle to Godrevy. Also an unconformity between the lower-mid Devonian rocks and much younger raised beach-like deposit and some boudinage and cleavage #geology #cornwall #CornishGeology #Variscan

#Deformation by the #Variscan #orogeny or as my humans say by an accident 280 - 380 Mill a ago ( +/- quit a lot, depending on definition) with the opponent's #Gondwana & #Laurussia involved. To our knowledge, the question of guilt has not yet been clarified #geology

Day 3 in Pembrokeshire and the #geology and the sun are still both shining 😎. The Lower Carboniferous limestones and shales exposed around West Angle Bay have been folded during the #Variscan Orogeny. Despite developing a strong cleavage original sedimentary ripples can be seen.
