The extent and nature of geological boundaries are represented by line features and described in terms of the type of boundary and the accuracy with which the boundary is located. It complies with the GeoSciML Portrayal standard for ContactView and fields required by that standard were populated using the CGI Controlled Vocabulary (2012-11). The data layer is part of the 'Geology of the Victoria Range' 1:50 000 dataset covering a part of of the Buller District on the West Coast of the South Island of New Zealand.

Annotation in this layer contains age information for point features in NZL_GNS_GM5_geochronology_50k. The data layer is part of the 'Geology of the Middlemarch area' 1:50 000 dataset covering a part of of East Otago around Middlemarch township.
