Marshall, P. 1918 The geology of the Tuapeka district, Central Otago division. Wellington: Government Printer. New Zealand Geological Survey bulletin 19 79 p.
Abstract: The area that is dealt with is that which contains the famous Tuapeka goldfields. It is a portion of the Central Otago division, and covers the survey districts of Tuapeka East, Tuapeka West, Waitahuna East, Table Hill, Waipori, and a portion of Tokomairiro. The area is bounded on the west by the Molyneux River, on the south by the watershed of the Tokomairiro River, on the north by the Lammerlaw Mountains, extending thence to the head of Post Office Creek, and from thence through Waipori Falls to Milton. The total area is about 500 square miles. The report embodies the results obtained during a special geological survey in the summer of 1915-16. (auth/DG)
