Abstract
The stratigraphy, metamorphic petrology and structural geology of a small area of amphibolite facies rocks have been investigated. A non-stratigraphic boundary separates the two major rock units in the area.
Mineral assemblages in pelitic rocks of the younger unit indicate that the area has undergone andalusite-staurolite metamorphism. No general conclusions can be drawn regarding either the metamorphism of the marbles of the same unit, or of the scapolitised pelitic schists of the older group.
Three main phases of deformation have been recognised in rocks of the area. Macroscopic and most mesoscopic folding is a result of the first phase of deformation. Second and third phases have involved a crenulation cleavage movement, but do not appear to have had a controlling effect on the macroscopic geometry.
