NettetAnswer (1 of 2): Foliation is the parallel arrangement of minerals eg mica in rocks while lineation is growth along this plane by mineral like hornblende.Schists and gniesses are exsmple of foliation. Nettet6.2.1 Foliation and Lineation. Foliation is a term used that describes minerals lined up in planes. Certain minerals, most notably the mica group, are mostly thin and planar by default. Foliated rocks typically appear as if the minerals are stacked like pages of a book, thus the use of the term ‘folia’, like a leaf.
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 … NettetFirstly, the crenulation must be analysed to determine the initial foliation, termed S 1, and the overprinting subsequent foliation. The intersection of these two planes forms an …
