Volcanic flow rocks cover approximately two thirds of the island, having been derived from a volcanic centre to the west of the island, which has been removed by marine erosion. Onland flows have been modified by radial drainage channels developed about the volcanic centre. The flow rocks are dominantly hawaiitic to mugearitic,with a smaller number of more evolved flows of the alkali olivine basalt lineage. Intrusive rocks are mineralogically and chemically similar to the flow rocks. Both are characterised by mineralogical and chemical homogeneity, but textural variety. The igneous rocks are believed to have been derived from melting of the mantle to produce an alkali basaltic parent,which has undergone subsequent fractional crystallisation,producing the observed rocks. There is little post eruptional structural modification, apart from the tilting of the Filhol Peak block. Department The department where the student is studying primarily.
