Occurrence of gabbro and basalt (undefined outcrop along the Rio del Rame, i.e. "Copper Creek"). According to the historical descriptions, analcime occurred as sharp icositetrahedral crystals (Bombicci, 1873), natrolite as prismatic crystals, several cm long (Bombicci, 1873; Artini, 1889) and laumontite as reddish fibrous-radiated masses (Bombicci, 1873).
