A tectonic analysis of the faulting and slickensides at the Woodsreef Asbestos Mine has resulted in the preliminary determination of the principal axes of Early Permian deformation that may have been responsible for the syntectonic emplacement of the serpentinite and the local development of the faults, fractures, schistosities and the asbestos fibres: lengthening (X)—18°, 258; shortening (Z)—72°, 097; and intermediate (Y)—4°, 348. These values are compatible with the known geometries of the structures in the Woodsreef Serpentinite and the X and Y directions are subparallel to the orientation of the asbestos fibres. These results can also be utilized to demonstrate the transtensional nature of the Peel Fault during the Early Permian.
