Two concepts are important : deformation phases and metamorphic events. The first relates to specific periods during which a rock is deformed under the influence of a deviatoric stress field, leaving visible records such as folds, cleavages or lineations. Successive deformation phases may be superposed on each other leaving overprinting structures such as folded foliations, refolded folds or folded lineations.  1, record 9, English, - deformation%20phase

The key toward the reinforcement-based design of geotextiles in reflective crack prevention in bituminous pavement overlays is the fabric’s effectiveness as determined by laboratory testing or experience. Quantitatively, it is defined as follows: FEF=N_r/N_n where FEF=fabric effectiveness factor, N_r=number of load cycles to cause failure in the fabric-reinforced case, N_n=number of load cycles to cause failure in the nonreinforced case. Values of FEF vary widely when based on laboratory tests (as they usually are), the range being from 2.1 to 15.9 ....  1, record 12, English, - geogrid%20effectiveness%20factor
