The thinnest recognizable layer of sediment, differing from other layers in color, composition, or particle size. Laminae are usually less than 1 cm (0.39 inches) thick.
The conception of the lamina leads immediately to two schemes, according to which a primary wave may be supposed to be broken up. In the first of these the element dS, the effect of which is to be estimated, is supposed to execute its actual motion, while every other element of the plane lamina is maintained at rest.
Now it is evident that the aerial motion in front of the lamina is determined by what happens at the lamina without regard to the cause of the motion there existing.
Imagine a flexible lamina to be introduced so as to coincide with the plane at which resolution is to be effected.
Or the thallus may have a leaf-like form, the branches from the central threads which form the midrib growing out mainly in one plane and forming a lamina, extended right and left of the midrib.
