ShearDisplacementStructure
Inspire revision 4711
Gyldig
A shear displacement structure includes all brittle to ductile style structures along which displacement has occurred, from a simple, single 'planar' brittle or ductile surface to a fault system comprised of 10's of strands of both brittle and ductile nature. This structure may have some significant thickness (a deformation zone) and have an associated body of deformed rock that may be considered a DeformationUnit

Type |
Multiplisitet |
| faultType |
|
Refers to a vocabulary of terms describing the type of shear displacement structure (eg; thrust fault, normal fault, wrench fault). |
FaultTypeTerm

|
1..1 |
| deformationStyle |
|
A mandatory element referring to a vocabulary of terms to describe the style of deformation, ie brittle (fault, breccia), ductile (shear), brittle-ductile, unknown. |

| planeOrientation |
|
Allows capturing the orientation of the plane of the structure |

1..1 |
| - convention |
|
The convention used for the measurement |

|
1..1 |
| - azimuth |
|
The azimuth (compass point, bearing etc) value of the orientation. Convention reports how azimuth is interpreted; if is quadrant. Allowance of different convention makes querying more difficult.

CGI_NumericRange
(datatype)
|
1..1 |
| - dip |
|
Dip is the angle that the structural surface (eg bedding, fault plane) makes with the horizontal measured perpindicular to the strike of the structure and in the vertical plane as a numeric or term

1..1 |
| - polarity |
|
Indicates whether the planar orientation is associated with a directed feature that is overturned, upright, vertical etc. |
