41. The steeply south dipping ( top of picture ) magmatic foliation parallels the hammer handle. 42. The Kronecker foliations of the 2-torus are the suspension foliations of the rotations by angle 43. The Kronecker foliations of the 2-torus are the suspension foliations of the rotations by angle 44. To qualify for the name a rock must also exhibit schistosity or some foliation or layering. 45. Metamorphic microstructures include textures formed by the development of foliation and overprinting of foliations causing crenulations. 46. Metamorphic microstructures include textures formed by the development of foliation and overprinting of foliations causing crenulations. 47. Identifying a foliation and its orientation is the first step in analysis of foliated metamorphic rocks. 48. "' Foliation "'in geology refers to repetitive layering in metamorphic rocks. 49. In 1978, E . Wagneur generalized the Reeb sphere theorem to Morse foliations with saddles. 50. Structural fabrics and defects such as faults, folds, foliations and underground mines or road tunnels.
