Skeletal Biomineralization: Pattern, Processes, and ...
The crypotcrystalline masses are roughly spherical with maximum diameters of
2.0 to 3.0 microns. The cryptocrystalline masses show no distinguishable
prismatic or pinacoidal faces even at high magnifications (greater than 20,000
diameters) ...

Crystal Identification with the Polarizing Microscope
In rare cases there may be morphological or other evidence suggesting the
identity of a pinacoidal cleavage. Prismatic cleavages are distinguished from
pinacoidal cleavages by their extinction characteristics or their relationship to
symmetry ...

Nanomaterials: Inorganic and Bioinorganic Perspectives
Such an investigation was performed by Larlus and Valtchev on zeolite L crystals
.m The typical morphology of zeolite L is a combination of two types of hexagonal
prisms, (100) and (1—10), and a pinacoidal face (001). The barrel-like crystals ...
