- LaboratoryAnalysis
- The LaboratoryAnalysis leaf package describes processes, instruments and result quality associated with quantitative analysis of samples.
- LaboratoryAnalysis-Specimen
- The LaboratoryAnlaysis-Specimen application schema extends the ISO19156 schema for Observations, Measurements and Sampling. It specifically describes processes and results related to the analysis of (geological) samples using instruments, most commonly in a laboratory environment. (Design of this package is based upon, and extends, the MOLES v3 data model.)
- Layering
- 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
- LinearDirectedCode
- eg,
"directed" (indicates that the orientation is directed)
"directed down" (indicates that the linear orientation is directed below the horizon)
"directed up" (indicates that the linear orientation is directed above the horizon)
This list is an indicative example list only of terms used to describe the values to use for terms related to directedness of linear orientations. Users are encouraged to use a vocabulary of terms managed by the CGI vocabularies working group outside of this model.
- Lineation
- GeologicStructure defined by aligned elongate elements. Lineation connotes a pervasive linear structure. Includes: flow lines, scratches, striae, slickenlines, linear arrangements of
elongate components in sediments, fold hinges (when abundant and closely spaced), elongate minerals, crinkles, and lines of intersection between penetrative planar structures.
Class also includes discrete linear structures like boudin, channel axis, tool marks.
- LineationTypeTerm
- Refers to a vocabulary of terms describing the type of lineation. Examples include: flow lines, scratches, striae, slickenlines, linear arrangements of elongate components in sediments, elongate minerals, crinkles, and lines of intersection between penetrative planar structures.
- LithologyTerm
- Refers to a vocabulary of terms describing the lithology of the compound earth material (eg, granite, sandstone, schist)
