Abstract
The anorthosite pluton has textural and trace element characteristics typical of a magmatic cumulate. A soda-rich intermediate magma is infe rred to be the parent. Rare earth element based modelling shows that t he anorthosite was derived from a parental melt having hundred times c hondritic REE with a slightly fractionated pattern probably derived by the melting of granulitic or eclogitic source.
