GeoMAP is a collection of datasets comprising geological information for Antarctica, including both rock and surficial deposit information. They have been compiled by the GeoMAP team led by GNS Science. This work utilised co-funding from GNS Science's Nationally Significant Databases and Collections Programme (NSDC) and international collaboration through the SCAR GeoMAP project.
GeoMAP represents a synthesis of existing published and unpublished mapping of the geology of the Antarctic continent in a single geodatabase at a regional scale. The data comprises geological unit polygon geometry and attribute fields describing the unit type, name, age, lithology, stratigraphy, and supporting background information, where this is known, and geological fault polyline geometry and attribute fields describing locational accuracy, exposure, fault type, and supporting background information, where this is known.
