Abstract
Summary: Geologically, the Ardmore area consists of Upper Devonian and Lower Carboniferous rocks lying in E.—W. folds which are transected by N.—S. faults. The orientations of all planar features were measured in localities chosen for detailed examination. The joints, veins and shear-planes were plotted stereo-graphically, and, from the resulting contour diagrams, structural maps were prepared. It has been established that the area has suffered three main phases of deformation—N.—S. compression, E.—W. tension, and clockwise shear, probably in that order. Deductions are drawn on the interrelation of the fracture-planes exemplified by the cleavage, joints, faults and other manifestations of crustal deformation.
