Dr A Brian Hawkins: Pyrite research compilation

Dr A Brian Hawkins

Dr Brian Hawkins, a former Reader in Engineering Geology at the University of Bristol and independent consultant engineering geologist, passed away in January 2016. A remembrance article for Dr Hawkins can be found at the University of Bristol news pages (here).

Research into the engineering implications of pyrite oxidation and sulfur-species

Since at least the 1980s, Dr Hawkins was involved with the examination of, and research into, cases of pyrite heave. He published two books and over 20 papers on the topic of pyrite oxidation and sulfur-species in geological materials. A list of Dr Hawkins’ major publications on the implications of pyrite oxidation for engineering/construction can be found below. Further information on Brian’s research and publications can be found here.
