Thompson, B.N. 1966 Geology of the Coromandel Region. Auckland: New Zealand Geological Survey. Report NZGS 14 22 p.
Abstract: In the Coromandel Region the rock types range from old, hard sedimentary rocks to youthful, loosely compacted beach sands; and from a large mass of igneous rock that cooled a mile or so beneath the surface at Moehau, to rocks that were erupted as widespread, hot avalanches that now cover much of the Peninsula. During this period of widespread volcanism came the emplacement of the precious-metal deposits of the Region. The accompanying geological map shows the distribution of the main types of rock outlined above. Although the geological structure is relatively simple, the area is not without problems of mapping and of interpretation. (auth)
