Example text

The deformation of the tectonite is either pre-crystalline, para-crystalline, or postcrystalline in relation to the crystallization of a specific mineral facies. If the deformation is pre-crystalline, we are concerned with a mechanical-chemical stirring-up (penetrative movement) with readjustment of a latent lack of equilibrium, as for example in the adaptation of the mineral facies of a crystalline magmatic rock to a deep zone or to a contact zone by tectonic penetrative movement; a similar adaptation of a sediment in which there is a lack of equilibrium between components; or tectonic transport with vertical components and ensuing consolidation by crystallization during a pause in the penetrative movement and transport.

Tangential undulation. Boundary surfaces on which beds slide over each other, may also be rhythmically warped. , and may be described purely kinematically and non-genetically as tangential undulation. The collation of all such cases, in terms of the movement picture, is not yet complete. Purely kinematically, the following is common to all these "undulatory displacements" in the widest sense: 1. The phenomenon occurs only in non-homogeneous domains, whether heterogeneous layers glide over each other—perhaps the heterogeneous condition resulting from discontinuously changing velocity gradients normal to the layers may be sufficient cause—or whether a materially different film, a heterogeneous boundary layer which has been there from the outset or has developed during the process, separates the neighbouring layers, or whether materially heterogeneous regions flow in conjunction.

Deformations with constant direction of all ellipsoidaxes proceed with constant orthorhombic symmetry. g. one with rotation-axis B, one with tan (a — a) = ^ ; tan a = INTRODUCTION TO CONCEPTS 39 rotation-axis A of the initial ellipsoid) and which proceed in triclinic manner (without axis or plane of symmetry) with frequent approach to almost monoclinic symmetry. To these "compound" deformations in the fabric also belong superimpositions at an oblique angle of affine deformations which can be distinguished from each other.
