This layer comprises geological unit data for Antarctica, rendered with chronostratigraphic symbology. It represents a synthesis existing published and unpublished mapping of the geology of this area in a single dataset for use at a continental to regional scale. The dataset consists of polygon geometry with each polygon having attributes describing the unit type, name, age, lithology, stratigraphy, and supporting background information, where this is known. This layer complies with the GeoSciML Lite standard for GeologicalUnitView and fields required by that standard were populated using the CGI Controlled Vocabulary (v2016.01). |
