The midribs of the leaflets the leaflets above have been shortened and d rotated toward (Figs. 215, 216), and unfortunately only a little shearing is enough to deprive them' of their value so far as this depends upon the recognition of species. In the deformation of any lithologic feature, all stages may exist between very slight change and very great change (212), and in rocks that have been intensely metamorphosed such original features may have been obliterated. Thus, curious though it may seem, the distinction between sheared quartz veins and sheared quartzite pebbles may be almost impossible in cases of extreme metamorphism. Lithologic structures in igneous rocks may likewise be deformed, but here one must be careful not to confuse phenomena due to magmatic flow with those which are of truly metamorphic nature (214). If possible it is good policy for the beginner to postpone studying highly metamorphosed rocks in the field until he has first become familiar with the primary characters of sediments and igneous rocks. 212. Degrees of Dynamic Metamorphism in Clastic Sedimentary Rocks.--Like contact metamorphism, dynamic metamorphism exhibits various degrees of intensity (121).
