2020 Pullar-Vucetich Prize winner:
Callum Rees
This year’s winner of the Pullar-Vucetich prize is Callum Rees, and his co-authors Julie and Alan Palmer, for three papers published in the New Zealand Journal of Geology and Geophysics in 2019:

Rees, C., Palmer, A., & Palmer, J. (2019). Quaternary sedimentology and tephrostratigraphy of the lower Pohangina Valley, New Zealand. New Zealand Journal of Geology and Geophysics, 62(2), 171-194. https://doi.org/10.1080/00288306.2018.1547321 (published online 25 Nov 2018).
Rees, C., Palmer, J., & Palmer, A. (2019). Whanganui Basin, an archive of prehistoric earthquakes? Waitapu Shell Conglomerate (c. 0.9 Ma), North Island, New Zealand.

This set of papers incorporates new analyses and identifications of Quaternary tephras and volcaniclastic beds in the Whanganui Basin, and their tephrochronological application to sedimentology, tectonism, and paleoseismology.

Alan Pullar and Colin Vucetich
In the 1950s and 1960s Alan Pullar (left) and Colin Vucetich (right) worked for the DSIR Soil Bureau, mapping soils in the North Island. Alan worked in Gisborne and Whakatāne, and Colin around Rotorua. They recognised that the soils were formed on volcanic ash layers, which were often visible in road cuttings.
The men started tracing out distinctive ash layers across the region. Work on ash layers (later called tephrostratigraphy) was outside official Soil Bureau policy and was banned. Much of their work was therefore done in weekends and holidays on what they called ‘secret correlation missions’.
Between 1963 and 1975 Colin and Alan published a series of papers on the sequence and characteristics of the main volcanic eruptions in the Taupō and Rotorua region. This work has been the foundation for later volcanological studies as well as the understanding of soil properties.
Initial funds for the Pullar Vucetich Prize were donated by family and colleagues of Alan Pullar and Colin Vucetich.
