Abstract: The general geology, petrography, and petrogenesis of the Benta Migmatite rocks are described and discussed in the light of two well-exposed sections near Benta, Pahang.
The rock which has previously been referred to as ” flow-banded syenite” is shown to be a gneiss in which large rapakiwi ellipsoidal microcline porphyroblasts have grown metasomatically.
The origin of the Benta rocks is considered to be deep seated. An anatectic origin is proposed for the monzonite and migmatite in place of the currently favoured hybrid origin, and no genetic relationship to the Benom granite is necessarily implied.
