WebFlower structures have evolved to maximize the chance of pollination, or fertilization of ovules by sperm cells contained in the pollen. The color, scent, nectar, and shape of a flower all help facilitate pollination through animal pollinators like insects, birds, and bats, or through wind, rain, and other physical phenomena. Transpressional shear zones are characterized by an association of structures that suggest zone-normal shortening and zone-parallel shearing. Commonly developed features include transposition foliations, lineations, stylolites, folds, and reverse faults. Pure shear-dominated transpression usually gives steep lineations, while simple shear-dominated transpression favors horizontal lineations. It is also common for non-vertical transpressional zones to have a significa…
