With a surface area of approximately 450 square kilometres, the Peridotite outcrop in the province of Malaga (Spain) is probably the largest on our planet and also the one with the greatest mineralogical diversity.
It emerged as a consequence of the collision of the Eurasian and African continental plates, which during the Oligocene period (between 34 and 23 million years ago) gave rise to the peridotite massifs of Ronda (called Sierra Bermeja) Ojén (Sierra de la Alpujata) Carratraca (Sierra de Aguas) and Casarabonela (Sierra de la Robla).
