Nelson Rock and Mineral Club
Nelson and Tasman boast some of the most varied geology in New Zealand. The area contains some of the oldest rocks in the country, yet shows also major impacts of geological forces operating right up to the present day, It is built of a complex series of igneous and volcanic and sedimentary rocks; it bears the marks of fierce seismic activity; it has rich mineral deposits and bears evidence to an exciting history of geological exploration and mining; its landscape has been shaped by erosion and deposition by glaciers, rivers, the sea, the wind and the the action of mass movement. Everything is here.
