Pedrera del Turó de Montcada

Limestone quarry on top of Montcada hill, 10 km north of Barcelona city. Geology consists of Silurian-Devonian slates, schists, marls and limestones, with several phosphate-rich beds and disseminations. Phosphate minerals are found in thin layers, nodules and veins mainly in Silurian slates.
The quarry is worked since 1917 and produces limestone rock for a cement factory belonging to the company ‘Compañía General de Asfaltos y Portland’ (ASLAND).
