An identifiable event during which one or more geological processes act to modify geological entities. A GeologicEvent must have a specified GeologicAge and may have specified environments and processes. An example might be a cratonic uplift event during which erosion, sedimentation, and volcanism all take place. Geological history is an ordered aggregation of Geological Event objects, each of which may have an associated Geological Age, Geological Environment, and one or more Geological Process objects. Genesis typically pertains to some geological phenomenon (Geological Structure, Earth Material, Geological Unit, Fossil, etc.) In GeoSciML 2.0 this ordering cannot be specified. A GeologicEvent must have a specified eventAge (numericAgeDate, olderNamedAge, or youngerNamedAge), at least one eventProcess, and may have specified eventEnvironments. An example might be a cratonic uplift event during which erosion, sedimentation, and volcanism all take place. Traditionally, geologists have described the age of a feature without explicitly specifying the event or processes the age related to. The GeologicEvent package allows for explicitly linking the three, without mandating it. The eventAge attribute is the age of a particular geological event or feature expressed in terms of years before present (absolute age), referred to the geological time scale, or by comparison with other geological events or features (relative age). An eventAge can represent an instant in time, an interval of time, or any combination of multiple instants or intervals. Specifications of age in years before present are based on determination of time durations based on interpretation of isotopic analyses of EarthMaterial (some other methods are used for geologically young materials). Ages referred to geological time scales are essentially based on correlation of a geological unit with a standard chronostratigraphic unit that serves as a reference. Relative ages are based on relationships between geological units such as superposition, intruded by, cross-cuts, or "contains inclusions of".

Planar foliation defined by a tabular succession of layers > 5 mm thick. This definition is based on the proposed definition of gneiss by the NADM Science Language Technical Team, so that the GeologicStructure characteristic of gneiss is layering. The committee discussed the possibility that layering should be considered a kind of foliation, but the majority opinion was that it is a different kind of structure. Kept so that instance documents have a "Layering" tag

A planar arrangement of textural or structural features in any type of rock. Includes any of a wide variety of penetrative planar geological structures that may be present in a rock. Examples include schistosity, mylonitic foliation, penetrative bedding structure (lamination), and cleavage. Following the proposed definition of gneiss by the NADM Science Language Technical Team, penetrative planar foliation defined by layers > 5 mm thick is considered Layering. Bedding as a fabric representing the average orientation of paleodepositional surface should be encoded through the foliationType; might apply to bedding that is layering or a foliation without layering (e.g. clast alignment in amalgamated beds).

Very general concept representing any kind of surface separating two geologic units including primary boundaries such as depositional contacts, all kinds of unconformities, intrusive contacts, and gradational contacts, as well as faults that separate geologic units. Permeability of contacts still needs to be modeled; considered out of scope for GeoSciML2. Bedding measured as discrete surfaces in the case that those are the feature of interest (e.g. individual cross set surfaces for paleocurrent analysis) should be represented here.

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).

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

A configuration of matter in the Earth based on describable inhomogeneity, pattern, or fracture in an EarthMaterial. The identity of a GeologicStructure is independent of the material that is the substrate for the structure. Properties like "clast-supported", "matrix-supported", and "graded bed" that do not involve orientation are considered kinds of GeologicStructure because they depend on the configuration of parts of a rock body. Includes sedimentary structures. The general GeologicRelation is used to associate penetrative GeologicStructures with GeologicUnits.

A composite structure that is an aggregation of genetically related instances of Faults and/or DuctileShearStructures. A FaultSystem is composed of individually identified and mapped Faults and/or DuctileShearStructures that are considered distinct ShearDisplacementStructures, that generally form overlapping, anastomosing patterns in which, at any point along the fault system, multiple fault strands are identified and each considered important at the scale of description. Displacement and other descriptive data may be assigned at the 'fault segment', 'fault', or 'fault system level'.

Fractures are cracks in the earth surface. If there is no displacement it is a joint. If there is displacement and you are in the brittle zone it is a fault. In the ductile zone, a fracture with displacement with fracture is called a shear. FaultSurface as a separate class is not considered necessary for GeoSciML 2. Recording observations on FaultSurface should be in observation and measurement. The observation needs to be able to distinguish the type of measurement made (PropertyType)

The GeologicRelation class is an abstract class that defines the general structure used to define relationships between any feature or object within GeoSciML. Relationships are always binary and directional. There is always a single source and a single target. The relationship is always defined from the perspective of the Source and is generally an active verb. Example: a Source may point to an intrusive igneous rock body. In this case, the Target would point to the appropriate host rock body and the relationship attribute would be 'intrudes'. Other appropriate relationship attributes might include: overlies, offsets, crosscuts, folds, etc. Many other types of relationships can also be accommodated via GeologicRelation, for example, topological relations between spatial objects could be described where they are scientifically significant.
