Foliation vs lineation
WebMylonite, Owl Mountains, Poland. Mylonite is a fine-grained, compact metamorphic rock produced by dynamic recrystallization of the constituent minerals resulting in a reduction of the grain size of the rock. Mylonites can have many different mineralogical compositions; it is a classification based on the textural appearance of the rock. WebThe opAMS foliation poles create an imperfect, NW–SE oriented girdle, whereas the opAMS lineations mostly trend NW–SE, perpendicular to most ipAMS lineations (Figure 14b). The AMR foliation poles create a relatively wide cluster near the center of the projection net and the AMR lineations show mostly NW–SE orientations (Figure 14c).

WebThe lineation plunges shallowly to moderately, trending either NW–SE or WNW–ESE with a few exceptions (Fig. 2 b). The quartzofeldspathic bands (observed in lineation-parallel and foliation-perpendicular sections) are in places thinned into pinch-and-swell structures and boudins that are mostly symmetric (Fig. 3 c). WebLineations. Associated with sigmoidal foliation, the stretched particles of the protolith typically are extended and define a stretching lineation which gives a streaky …

These patterns are dependent upon the original orientation of the L 1 lineation relative to the F 2 fold axis. Following Goscombe and Trouw (1999), φ is defined as the acute angle between the lineation and the fold axis. Where φ is 90°, the …
WebBy contrast, anisotropy of Q is very low at low confining pressure and markedly enhanced as pressure is increased. At high confining pressure, substantial anisotropy of Q in P waves is apparent but reversed from that of P wave velocities: Qp is highest in the direction normal to the foliation plane whereas Vp (and VS) is lowest in this direction.
