PLASMIC STRUCTURE

Asepic Plasmic Fabrics. Dominatly anisotropic plasma with anisotropic domains that are unoriented with regard toeach other; virtually no plasma separations

Argillasepic Fabric. Plasma consists dominatly of anisotropic clay minerals and exhibits a flecked orientation pattern with recognizable domains.
Silasepci Fabric. Exhibits a wide range of particle sizes with relatively high proportions of silt size grains so that domians are difficult to recognize; the matrix has a flecked extinction pattern.

Sepic Plasmic Fabrics. Recognizable anisotropic domains occur with various patterns of preferred orientation. Plasma separations with a triated extinction pattern are present.

Insepic Fabric. The plasma separations with striated orientation occur as isolated patches, or islands, within the dominantly flecked plasma, which may have a very weak striated orientation at high magnifications.
Mosepic Fabric. This is an extreme development of insepic fabric.
Vosepic Fabric. Part of the plasma has a flecked orientation pattern, but plasma separations with striated orientation occur subcutanically associated with the walls of voids.
Skelsepic Fabric. Part of the plasma has a flecked orientation pattern, but the plasma separations with striated orientations occur subcutanically to the surfaces of skeleton grains.
Masepic Fabric. Part of the plasma has a flecke dorientation pattern, but plasma separations occur as zones within the s-matrix apparently not associated with the walls of voids or the surface of skeleton grains; the striated orientation is elongated parallel to the length of the zones.
Lattisepic Fabric. Acicular and prolate domains occur in a lattice-like pattern. Two sets of very shor, discontinuous plasma separations usually oriented at right angles to each other.
Omnisepic Fabric. All the plasma exhibits a complex striated orientation pattern.

Crystic Plasmic Fabric. The plasma is usually anisotropic and consists of recognizable crystals, usually of the more soluble plasma fractions.

Isotic Plasmic Fabric. These fabrics have apparently isotropic plasma.

Undulic Plasmic Fabric. The plasma is indeterminat; it is practically isotropic at low magnifications and weakly anisotropic with faint undulose extinction at high magnifications and high light intensities.
