This collection of datasets contains the 1:50 000 geological data for the Middlemarch area, East Otago, New Zealand (Topo50 sheet CD16).

They spatially represents an interpretation of geological and geophysical information compiled from new field work and existing data. The mapping frame for the majority of datasets is defined as surface geology (i.e. the bedrock and superficial deposits that would be visible if the overlying soil was removed or are exposed at the topographic surface). The data structure complies with the GeoSciML Portrayal standard where one exists and fields required by that standard were populated using the CGI Controlled Vocabulary (2012-11). The data should not be used at scales beyond that for which it was prepared. The spatial accuracy is estimated to be no better than +/- 100 m.

The datasets were produced by GNS Science and are associated with Martin, A.P.; Cox, S.C.; Smith Lyttle, B. 2016: Geology of the Middlemarch area 1:50 000. GNS Science geological map 5. Lower Hutt, New Zealand. GNS Science.
