3TK-PD8Ilmenite, Titanite

Montoso Quarries, Bagnolo Piemonte, Cuneo Province, Piedmont, Italy

Field of View: 3.4 mm

Rutile and titanite commonly form by replacement of ilmenite in metamorphic rocks.
Ilmenite reacts during metamorphism above 1.2-1.4 GPa to form rutile. Below this pressure, titanite is the dominant Ti-bearing species for most granitoid compositions.
The position of this reaction curve is strongly influenced by the whole rock Ca activity. For low Ca activities, rutile may be stable down to 0.7 GPa (and below) within ilmenite pseudomorphs while the titanite stability field may extend to pressures >1.3 GPa for Ca-richer compositions.
In this case we have an interesting sample of corroded Ilmenite partially turned into titanite (white dots at the bottom right).
Sample self collected at Bricco Volti quarry, Montoso.
