Rhodolith bed, Spain

Volcaniclastic sandstone package with a rhodolith-rich bed at the base. These beds form the beginning of the Tortonian-Messinian sedimentary sequence above the volcanic basement (Serravallian - Tortonian) in this area, and contain rounded volcanic cobbles and pebbles. In fact, many of the rhodoliths have volcanic fragments as a core: one is labeled in the model, but you can find several more. A few meters above the sandstone, the sedimentary sequence continues with carbonatic turbidites. In default view, the outcrop is oriented with ENE to the left and WSW to the right.
