2019 Hornibrook Award winner:
Through detailed mapping in the field and complemented by GIS, Oliver McLeod has subdivided the volcanic stratigraphy of Pirongia multiple stages and volcano-stratigraphic units. He has had to apply novel techniques to characterise and correlate volcanic units and successions across the irregular and discontinuous stratigraphy of a partly eroded Early Pleistocene volcanic edifice.
The work will be published as a volcanic geological map and bulletin as a Geoscience Society of New Zealand Miscellaneous Publication. This volcanic stratigraphy will inform the petrological understanding of Pirongia and enable Oliver and future researchers to consider novel applications of geochemical datasets to understanding the volcanic history of the volcano.

Norcott (Horni) Hornibrook (1921-1994) was brought up in Tauranga, Napier and Gisborne. Immediately after leaving school he got a job as a geologist's assistant with NZ Petroleum Company in Gisborne, and then as a micropaleontology technician with the NZ Geological Survey in Wellington.
His career was interrupted by WW2 following which he returned to New Zealand and returned to the Survey and university education. When Survey micropaleontologist Harold Finlay died in 1951, Horni became chief micropaleontologist - a position he held until his retirement in 1981.
Despite his retirement Horni continued his research at the Survey right up until his death. Building on the initial work of Finlay, Horni became the father of New Zealand foraminiferal biostratigraphy. Although Horni spoke up against the creation of the Geological Society, he became one of its founder members, was one of its most active Presidents (1966-68), and one of its staunchest supporters.
Horni’s colleagues funded the Hornibrook Award in biostratigraphy.
