Figure 5.18: AFM images of the nacreous layer (a), intersection between the nacreous and calcite layer (b) and the intersection between the nacreous and prismatic layers (c).
Images captured by AFM show the topography in three dimensions of a L. fortunei shell. In the image we see the nacreous layer with the visible adjustment between the tiles in 5.18.a. In figure 5.18.b, the transiton from the nacreous layer to the calcite layer. In figure 5.18.c, the prismatic layer with an accentuated topography immediately after the nacreous layer. In this image, the relatively homogeneous area is resin.
