Name(s) in local language(s):
Cerro del Hoyazo / Cráter de las Granatillas (Cráter de La Granadilla), Níjar, Almería, Andalucía, España
Old underwater volcanic cone topped by a coral reef crown of 600 m in diameter. Volcanism is the calc-alkaline potassic type. Rocks are biotite-rich dacites with many phenocrystals of almandine, plagioclase, cordierite, biotite, and xenoliths of cordierite / sillimanite gneiss and other metamorphic rocks.
Due to almandine-rich dacite weathering and decomposition, some areas of the crater bottom are sown with trapezohedral garnets up to 1.5 cm.
Placers of garnet-rich sand in the dejection cone of waters coming from El Hollazo basin through Rambla de las Granatillas were exploited in the first third of last century and reactivated in 1996 for a few more years.
Samples used for the cordierite mineral species' first description by Von Schlotheim in 1801, calling it "Spanischer Lazulith", were likely collected here; later, using samples of the San Pedro de Pinatar (Murcia), Pierre Cordier, with the help of René Just Haüy, described again the mineral and gave its definitive name.
