Clinohumite specimens from the Sierra de Mijas are a classic of Spanish mineralogy. These specimens are treated using chemical processes to make the crystals emerge in the marble matrix. They are accompanied by dark violet octahedral crystals of spinel. Clinohumite is a member of the humite group. It forms a continuous series with hydroxyclinohumite. The name "clinohumite" has commonly been used when the F/OH ratio has not been determined. Mijas is a magnesium skarn embedded in marble and pelitic gneiss, amphibolites and granulitic gneiss, in the zone with alpine peridotites-serpentinites (Sierra de Mijas). c6y58
