| Description | Journal: New Zealand Journal of Geology and Geophysics This report describes volcanic ash beds that occur north of Otorohanga and west of Tirau in the central part of the North Island of New Zealand. The beds lie above one another as a mantle on the land surface, and form the parent material for many modern soils. Many of the beds, before burial by younger ash, were exposed to processes of soil formation and, as a result, the deposits include many fossil soils. Although their significance to agriculture is very well appreciated, the value of the beds for correlating terrestrial Pleistocene deposits and erosion surfaces is not widely recognised. A prominent break occurs within the ash deposits and marks a lengthy time interval. The name Kauroa Ash Formation is proposed for the beds below this break, and for the younger beds above it the name Hamilton Ash Formation is used. The beds of Hamilton Ash Formation post-date the early Pleistocene 220-250 ft terrace but pre-date the middle Pleistocene 110–130 ft terrace. |
