Speight, R.; Page, S. 1928 The geology of the Malvern Hills. Wellington: Government Printer. Geological memoirs / New Zealand Geological Survey 1. 72 p.
Abstract: In the early days of geological work in New Zealand the Malvern Hills district attracted considerable attention, chiefly, perhaps, since it promised to provide a considerable amount of coal for a region deficient in fuel, but also because it furnished points of purely scientific interest. The fact that the latest account of the area was given in 1884 - that is, forty years ago - has prompted me to redescribe it in the light of more modern knowledge, and hence the following account.
