<p><span>The geometry of individual </span>major<span> </span>folds<span> from the Glen Cannich area in the Northern Highlands of Scotland is described. The </span>major<span> </span>folds<span> are isoclinal, </span>and<span> their axial planes </span>and<span> </span>fold<span> limbs strike north or northeast </span>and<span> dip steeply; the </span>fold<span> axes plunge steeply toward the south or southeast. If pairs of individual </span>folds<span> are joined along a common axial-plane trace they form basins, domes, or other unusual culmination structures which resemble intensely flattened cylinders. As a group, the basins </span>and<span> domes form a continuous </span>pattern<span>, which covers an area of approximately 27 square miles, with possible extension into surrounding areas. This </span>pattern<span> has resulted from the </span>interference<span> of two sets of </span>major<span> </span>folds<span>, whereby the movement direction of the second </span>fold<span> set lay close to the axial plane of the first </span>fold<span> set. The geometrical conditions </span>and<span>/or intensity of the second </span>folds<span> that obtained during the second folding have rendered the first </span>fold<span> set unmappable, because the basins </span>and<span> domes are elongated entirely in the direction of the second </span>fold<span> set. The probable orientation of the first-</span>fold<span> axial plane is suggested by joining the culminations or depressions of the basm-</span>and<span>-</span>dome<span> </span>pattern<span>. Subsequent deformations have substantially altered the </span>basin<span>-</span>and<span>-</span>dome<span> </span>pattern<span> from its probable original form. </span></p>
