CHAPTER 3. SIMULATION OF IGNEOUS DIFFERENTIATION PROCESSES
The Pitcairn hotspot, located about 60 km east of Pitcairn Island (South Pacific), consists of several active volcanoes < 500 m below sea level. The volcanic rocks from these seamounts are classified in four main rock-types: (1) picritic basalt containing Ti-bearing chromite (8–10 wt.% TiO2); (2) alkali basalt (Ti-bearing chromite with 4–6 wt.% TiO2); (3) trachyandesite containing titanomagnetite (18–22 wt.% TiO2); and sulfides, and (4) trachyte (titanomagnetite with 19–23 wt.% TiO2); The metallic oxides are zoned with decreasing Tîl02 contents from core to rim. Crystal fractionation (> 60%) is the main process responsible for differentiating these rock-types from an enriched source.
