Detailní popis produktu

The Heemskirk granite massif was intruded as a diapir about 354 m.y. ago into Precambrian and Palaeozoic sediments. It fractionated into two types the red and white granites, which are distinguished by their colour and mineral and chemical composition. It is suggested that they also differed in volatile content and oxygen fugacity. The characteristic mineral assemblage of the red granite (hematite – magnetite – allanite) indicates a higher oxygen fugacity than the white type, which is characterised by tourmaline.
