New Zealand historical geology. The geological timescale is the time framework by which we date, correlate and clasify rock formations and geological events. It provides the time framework for all studies of the history of the Earth and its life. It is used for assigning geological age to rocks, fossils and economic minerals, and for calibrating the rates of geological processes such as fault displacement and plate rotation, submergence, uplift and erosion of the land, earthquake frequency and volcanic activity. Rates of climate change, sea-level change, biodiversity change and organic evolution are also measured in terms of the geological timescale. Timescales play an important part in the search for petroleum and coal resources. It is essential, therefore, that we have the most accurate and precise timescale available.
