Well-developed penetrative
crenulation cleavages are concentrated by fine grained biotite.
Nonetheless, there is a certain correlation in the conclusions to be drawn from these tables, with variables such as
crenulation, kinkband, and microfracture remaining significant; RQD, on the other hand, was not significant at 5% level.
Topomorphic variation can be also the degree of
crenulation of corallites in H.
These are Carabelli's cusp ("American Caucasoid"); shoveling of incisors, incisor rotation, enamel extensions, and buccal pits ("Southwestern Mongoloid"); and molar
crenulations ("American Black").
With increasing metamorphic conditions, the protoliths of the staurolite-bearing metapelites were tectonically transported and buried to its maximum depth at the [P.sub.peak], (in the staurolite zone) which is attributed to crustal shortening and thickening accompanied by deformation, which produce, respectively, a slaty cleavage Si and a
crenulation cleavage [S.sub.e] associated with thrusting.
Le [F.sub.1] est cause par la formation d'un pli ([F.sub.2]) non coaxial plus dominant, a vergence est et d'orientation NNE-NNO ainsi que par une schistosite de
crenulation ([S.sub.2]) amplifiee en raison d'une dissolution par pression connexe.
avonia (see Karatajute-Talimaa 1978; Marss 1996; Turner 2000) and a less complicated
crenulation on the crown margins than L.
D2 event has an extensional character (Diez Balda et al., 1995) and it is characterized by recumbent folds associated with dextral shear zones (N40-N60) with an axial plane
crenulation cleavage or schistosity (S2).
In these rocks, [S.sub.2] is observed as
crenulation foliation and/or fracture cleavage that developed from [S.sub.1] (Figure 3i).
The second cleavage crenulates and transposes the first, which typically carries a slicken lineation where lithons are deformed by
crenulation. Thin section and scanning electron microscope images reveal that these cleavages are defined by microveins of calcite, gypsum, and montmorillonitic clays with hematite and vivianite, and that there is some evidence for silica dissolution.
1) are roundish to oval, with a rich
crenulation around the crown margin.
