Inspire revision 4711 Gyldig

One or more systematically curved layers, surfaces, or lines in a rock body. Fold denotes a structure formed by the deformation of a GeologicStructure to form a structure that may be described by the translation of an abstract line (the fold axis) parallel to itself along some curvilinear path (the fold profile). Folds have a hinge zone (zone of maximum curvature along the surface) and limbs (parts of the deformed surface not in the hinge zone). Folds are described by an axial surface, hinge line , profile geometry, the solid angle between the limbs, and the relationships between adjacent folded surfaces if the folded structure is a Layering fabric (similar, parallel).

- estimatedValue A single measured value chosen on some basis (eg; mean, mode, median, best guess) that is representative for the measurement. Best practice to consider the value and uom attributes of swe:Quantity to be mandatory. Quantity 1..1
axialSurfaceOrientation 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. CGI_PlanarOrientation (datatype) 1..1
- convention The convention used for the measurement ConventionCode (kodeliste) 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 CGI_NumericRange (datatype) 1..1
- polarity Indicates whether the planar orientation is associated with a directed feature that is overturned, upright, vertical etc. PlanarPolarityCode (kodeliste) 1..1

hingeLineOrientation 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. CGI_LinearOrientation (datatype) 1..1
- directed To indicate if orientation represents linear feature that is directed, e.g. clast imbrication, mylonitic lineation with sense of shear, slickenlines with displacement direction, rather than undirected. A code list to indicate which is the directed end of the linear orientation LinearDirectedCode (kodeliste) 1..1
- plunge Magnitudeof the plunge. May be a term (eg steeply) or numeric (eg 75 degrees) or range. CGI_NumericRange (datatype) 1..1

symmetry 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) CGI_Term (datatype) 1..1

GeologicStructure
GeologicFeature
observationMethod Feature ObservationMethod specifies the approach to acquiring the collection of attribute values that constitute an individual feature instance (e.g. point count, brunton compass on site, air photo interpretation, field observation, hand specimen, laboratory, aerial photography, creative imagination). ObservationMethod is a convenience property that provides a quick and dirty approach to observation metadata when data are reported using a feature view (as opposed to observation view). For a borehole, the GeologicFeature observation method specifies how the geologic properties were determined (eg, visual observation, or standard AzGS logging procedure (described in detail somewhere else)). This property corresponds (loosely) to ISO19115 Lineage. CGI_Term (datatype) 1..*
