Visiting Cork County 🇮🇪☘️ was a real structural #geology feast🤩
I’ll start with #boudinage, the extensional structure of a rigid layer is stretched and deformed between less competent surroundings.

Shanvallybeg Beach near Bantry

Outcrop of folded and boudinaged marble. The white/grey stuff is calcite-rich, the brown/orange stuff is dolomite-rich. Green layers contain phyllosilicates.

A layer of metaconglomerate, a type of metamorphic rock, extended and fractured by tectonic forces, with fractures filled with white quartz deposited from a fluid. This feature in geology is known as 'boudinage'

#Boudinage are one of the most spectacular geologic structures. The boudins are the eye-shaped lenses of rock wedged between the white quartz layers. Find out how they formed at the link below. Fascinating! ⚒️🧪 geology @flintironstag.bsky.social
