Graphite is highly concentrated in well-developed horizontal crenulation cleavages which is later crenulated by young differential cleavage.

The crenulation of the corallite wall in this species is environmentally affected, because it appears randomly in some coralla and strongly and more often in other coralla (Pl.
New traits could include UI1 labial convexity, UI1 midline diastema, the mesial canine ridge, and molar crenulations, traits that are more common in Sub-Saharan Africans than other populations of the world (Irish 1993, 2013, 2016; Pilloud et al.
The second phase of deformation ([D.sub.2]) formed open to tight [F.sub.2] folds of bedding, [S.sub.1A] and S.sub.1B] and an axial planar [S.sub.2] crenulation cleavage enhanced by pressure solution.
[S.sub.3], is represented by the folding of flanks of crenulation foliation ([S.sub.2]) and defined by graphite and bent muscovites (Figure 3j).
La deuxieme schistosite donne lieu a une crenulation reportee a partir de la premiere schistosite, laquelle comprend une lineation de glissement classique dom les lithons ont ete deformes par crenulation.
6c) are deforming the Chanic cleavage ([S.sub.1]) and often are accompanied by a crenulation cleavage ([S.sub.2]).
Crenulate, 9-10 crenulations in 0.1 mm; each crenulation is associated with a yellow area, each paler area longer than wide (Fig.
The most conspicuous structures are upright to overturned, open to tight [F.sub.2] folds with chevron profiles, a locally well-developed axial planar slaty cleavage ([S.sub.2]) and a related crenulation lineation on [S.sub.1]([L.sup.1.sub.2]).
