Entity_and_Attribute_Information:
Detailed_Description:
Entity_Type:
Entity_Type_Label: Geochronology
Attribute:
Attribute_Label: FID
Attribute_Definition: Internal feature number.
Attribute_Definition_Source: ESRI
Attribute_Domain_Values:
Unrepresentable_Domain:
Sequential unique whole numbers that are automatically generated.
Attribute:
Attribute_Label: Shape
Attribute_Definition: Feature geometry.
Attribute_Definition_Source: ESRI
Attribute_Domain_Values:
Unrepresentable_Domain: Coordinates defining the features.
Attribute:
Attribute_Label: LABNO
Attribute_Definition:
A reference number to indicate a unique entry in the Canadian Geochronology Knowledgebase
Attribute:
Attribute_Label: SAMPLENO
Attribute_Definition:
sample number - either the sample number indicated in the publication, or one assigned using the rock's published name
Attribute:
Attribute_Label: AGE
Attribute_Definition:
The interpreted age of the rock or mineral given in millions of years (Ma). All ages have been corrected to the recommended decay constants of Steiger and Jager (1977).
Attribute:
Attribute_Label: ERR_PLUS
Attribute_Definition:
2 sigma positive uncertainty in Ma. This is 0 when no error is given by the author.
Attribute:
Attribute_Label: ERR_MINUS
Attribute_Definition:
2 sigma negative uncertainty in Ma. This is 0 when no error is given by the author.
Attribute:
Attribute_Label: AGE_METHOD
Attribute_Definition:
Isotopic system or methodology used to derive the age (e.g. U-Pb, Ar-Ar, fission track).
Attribute:
Attribute_Label: AGE_INTERP
Attribute_Definition:
A general category that describes the type of geological event dated (e.g. cooling, igneous crystallization etc.).
Attribute:
Attribute_Label: AGE_NOTE
Attribute_Definition:
A text descriptor highlighting salient features used by the author in arriving at the published interpretation of the date.
Attribute:
Attribute_Label: AGE_MATERI
Attribute_Definition: The mineral or material (e.g. whole rock) analyzed.
Attribute:
Attribute_Label: ROCKTYPE
Attribute_Definition:
Broad categorization of rock into one of five types: Plutonic, Volcanic Sedimentary, Metamorphic or Hydrothermal.
Attribute:
Attribute_Label: AGE_TECHNI
Attribute_Definition:
The analytical technique used to determine the age (e.g. SHRIMP, TIMS)
Attribute:
Attribute_Label: AGE_QUALIF
Attribute_Definition:
A qualifier describing constraints on the age. "Direct" means analytical errors are statistically representative; "Estimate" is used when the author indicates no statistical validity to assigned errors. Other qualifiers include "Maximum Age" (i.e. statistical limit on how old the sample can be) and "Minimum Age" (i.e. statistical limit on how young the sample can be).
Attribute:
Attribute_Label: GEOLOGICAL
Attribute_Definition:
A broad category indicating which major geological province the sample was collected from.
Attribute:
Attribute_Label: UTME
Attribute_Definition: UTM easting, NAD83 zone 13
Attribute:
Attribute_Label: UTMN
Attribute_Definition: UTM northing, NAD83 zone 13
Attribute:
Attribute_Label: GEOLOGIC_1
Attribute_Definition: Description of the geological framework (e.g. unit, formation)
Attribute:
Attribute_Label: ROCKDESC
Attribute_Definition: Brief text description of rock lithology.
Attribute:
Attribute_Label: AUTHORS
Attribute_Definition:
Text string with a list of authors in standard reference format.
Attribute:
