Appendix I: OneGeology English keyword dictionary picklist

To help classify your service in the portal with respect these thematic keywords you can use one or more of the optional thematic@value style keywords in your layer metadata.

Note, terms like Geology shown in bold help to classify the terms for ease of reading, but don't imply any hierarchy. These terms are also part of the picklist of terms.

Term Definition
Geology Earth’s history and its life as recorded in the rocks; includes the study of geologic features of an area, such as the geometry of rock formations, weathering and erosion, and sedimentation.
Bedrock Consolidated rock
Superficial deposits Unconsolidated/quaternary geological deposits
Surface geology Superficial deposits and bedrock which occurs at the Earth’s surface
Borehole Boreholes or data surveyed in boreholes
Geochronology Absolute ages of rocks, fossils, and sediments, within a certain degree of uncertainty inherent to the method used
Radiometry In optics, radiometry is a set of techniques for measuring electromagnetic radiation, including visible light.
Absolute age The geologic age of a fossil, or a geologic event or structure expressed in units of time, usually years.
Stratigraphy Rock and sediment layers and layering (stratification)
Biostratigraphy The branch of stratigraphy which focuses on correlating and assigning relative ages of rock strata by using the fossil assemblages contained within them
