The main crystals are stellar crystal, column, irregular crystal

8A-C); 5) the absence of fabrics that are characteristic of neomorphic calcite ("all transformations between one mineral and itself or polymorph"; Folk, 1965), such as irregular crystal
sizes, wavy or curved inter-crystalline boundaries, and floating relics in the interior of the crystals.
Summary: TEHRAN (FNA)- Results of new studies showed that shoals of fish and swarms of krill hang out in groups that take on the same overall shape, which is not a simple sphere, a cylinder, or ovoid, but something more akin to an irregular crystal
However, their presence does cause a more irregular morphology, as these particles perturb the crystallization of the solvent and change the patterns of crystal growth, forming more irregular crystals
in the solvent.
Regular shape particles were formed from solutions of low dielectric constant such as ethanol and THF and irregular crystals
were formed from a solvent with a higher dielectric constant such as water.
Strains isolated from Braulio Carrillo, Tortuguero and Cahuita, presented predominantly irregular crystals. On the other hand, more than 60% of the isolates from Terraba-Sierpe and Hitoy-Cerere had medium oval crystals.
Also, some strains presented small and large bipyramidal as well as irregular crystals (Fig.
