Nelson map

Geological Summary

The urban area of Nelson has a complex variety of Late Paleozoic to Mesozoic igneous and sedimentary basement rocks exposed in the hills to the east. Hills around central Nelson are comprised of Eocene, Miocene and Pliocene sandstone, mudstone and limestone, overlain in places by Quaternary alluvial and colluvial sediments, particularly in valley floors and near flatter coastal areas. The Quaternary sediments dominate the near-surface geology of Tahunanui, Stoke, Richmond and Hope.

Maps and Information

There are no geological mapping projects underway or imminent in the Nelson area. Previously completed maps include:

1998/2018: QMAP 1:250 000 geological map

For wider and more generalised geological context of the Nelson area, a 1:250 000 geological map was printed with an accompanying an explanatory text. Digital GIS and image versions of the map are available on DVD. The digital version has since been updated in a national GIS dataset at that nominal scale. The underlying GIS datasets have rich feature attributes.
