axialSurfaceOrientation |
estimatedProperty |
This is used to characterize the geometry of a fold. The axial surface of a particular fold may be located based on observations of the folded geologic structure, but in general it has no direct physical manifestions. As a geologic surface, it has geometric properties, including orientation, which may be specified by observations at one or more locations, or generalized using terminology (upright, inclined, reclined, recumbent, overturned). Dip and Dip Direction are one approach to specifying the value. |

geneticModel |
estimatedProperty |
Specification of genetic model for fold, e.g. flexural slip, parallel

hingeLineCurvature |
estimatedProperty |
variation in orientation of fold hinge along trend of fold, distinguish sheath from cylindrical folds. Specify with terminology eg sheath, dome, basin, cylindrical.

hingeLineOrientation |
estimatedProperty |
Specification of hinge line orientation for fold. CGI_LinearOrientation allows for a term value specification or a numeric specification of either or both the trend and plunge of hinge line. kHinge plunge term examples: sub-vertical, steeply plunging, ... sub-horizontal, reclined and vertical for special cases in which hinge plunge is close to axial surface dip. 0..* cardinality allows for both a numeric specification a term specification. |

hingeShape |
estimatedProperty |
rounded vs. angular hinge zones; has to do with proprotion of wavelength that is considered part of hinge

interLimbAngle |
estimatedProperty |
Specify using a tightness term (gentle (120-180), open (70-120), close (30-70), tight (10-30), isoclinal (0-10)) |

estimatedProperty |
straight vs curved limbs, eg kink, chevron, sinusoidal, box

profileType |
|
Terminology specifying concave/convex geometry of fold relative to earth surface, and relationship to younging direction in folded strata if known. (eg; antiform, synform, neutral, anticline, syncline, monocline, ptygmatic) |

span |
estimatedProperty |
linear distance between inflection points in a single fold
|
CGI_NumericRange |
1..1 |
symmetry |
estimatedProperty |
concordance or discordance of bisecting surface and axial surface, or ratio of length of limbs. Folded surface may have asymmetry defined by limb length ratio if inflection points are defined. Defintion based on bisecting surface/axial surface angle depends on having multiple surfaces defined such that the axial surface may be identified. (symmetric, assymetric)
