Parental liquids of the Skaergaard intrusion cumulates

Abstract

Petrogenetic relationships between compositions advocated as possible liquids parental to the Skaergaard layered series cumulates have been investigated using equations for the prediction of liquidus temperature and liquid path followed during fractional crystallization. Given a suitably defined sequence of primocryst mineral assemblages, a variation of the fractionation scheme provides a new method for the calculation of the parent liquid composition.
