NettetC-S fabrics Figure 4. C-S fabric. In some shear zones, strain is obviously partitioned such that zones of intense shear, and grain size reduction, alternate with zones of less intense strain, where the foliation is more oblique and the grain size is coarser. This configuration is called C-S foliation (sometimes S-C). The C-planes (where ‘C’ stands for … NettetYou can see that foilation is two dimensional while lineation is one. Foliation in geology refers to repetitive layering in metamorphic rocks.Each layer may be as thin as a sheet of paper, or over a meter in … NettetFirstly, the crenulation must be analysed to determine the initial foliation, termed S 1, and the overprinting subsequent foliation.
