Undirhlíðar quarry on the Reykjanes Peninsula in southwest Iceland exposes an almost complete cross-section of a pillow-dominated tindar. Detailed mapping and geochemical analyses of the quarry walls show that glaciovolcanic lithologies are controlled not only by ice conditions, but also by complex changes in magmatic conditions. Undirhlíðar's glaciovolcanic deposits are dominated by ...
