Slot grid is held under water beneath a ribbon, using an eyelash to coax the ribbon toward the slot, while raising the grid slowly out of the boat. C. WebThe micritization of broken skeletal and non- skeletal grains, that is the recystalization of a preexisting crystal fabric to a micritic one, also adds to the confusion. This is because these micritized grains may be mistaken for fragments of sedimentary micrite. Micrite cement is discussed in the section on cementation and diagenesis.
