Geological Map and Cross Sections of the Nelson-Richmond Urban Area (South Island, New Zealand)

The Revised Geological Map of the Nelson-Richmond Urban area by M.R. Johnston, F. Ghisetti, P. Wopereis (2021) is a geo-referenced geological map superposed onto the NZTM2000 Topo50 Map BQ 26 (Nelson), This map updates the geology and structural setting of the Late Cretaceous-Quaternary units overlying the Eastern Province terranes, that were originally mapped by Johnston (1979, 1981; 1982). The revised map incorporates new stratigraphic and structural data made available in the last four decades by exposures at building sites, boreholes and trenches, as well as geomorphic information from LiDAR surveys undertaken by the Nelson City and Tasman District councils.
