The geometric arrangement of component features (i.e., minerals and mineral aggregates) in the rock.
Fabric
Formed during the genesis of the rock (e.g., beddings, flow banding in lavas, magmatic layering).
Primary Fabrics
Products of ductile deformation and are systematically associated
with tectonic stress.
Secondary Fabrics
Where are Secondary Fabrics commonly observed?
Tectonites
These are strongly deformed metamorphic rocks
Tectonites
A Nature of Tectonites where it is dominated by foliation.
This rock may tend to split
into sheets parallel to
the foliation.
S-Tectonites
A Nature of Tectonites, where the alignment of the linear fabric
elements create the dominant fabric, so the rock may split into rodlike shapes.
L-Tectonites
A Nature of Tectonites, where it possesses a strong foliation and a strong lineation
L/S-Tectonites
A Category of Fabric where the elements have no preferred orientation.
Random
A Category of Fabric where the elements are aligned in some manner and repeated at a regular spacing.
Preferred
A Category of Fabric where the elements are planar or tabular, and parallel to one another.
Planar or Foliation
A Category of Fabric where the elements are linear.
Linear or Lineation
The behavior of Fabric where it has space visible between the fabric elements.
Spaced Fabric
The behavior of Fabric where it continues to be visible no matter how small your field of view.
Continuous Fabric
If spacing is >1mm, the fabric is?
Spaced Fabric
If spacing is <1mm, the fabric is?
