Research interests

Research topics: Geochemistry; Archaean Geology; Crustal evolution; Mantle geochemistry; Chromite mineralisation. Over the past 30 years my research has focused on two main themes - namely geochemistry and the very early part of Earth history - the period of time we call the Archaean.

My work has been summarised in two text books which cover these two themes:

• ROLLINSON H.R., 1993, Using Geochemical Data: Evaluation, Presentation, Interpretation, Longman, UK. 352 pp. [Co-published by J. Wiley & Sons. Inc. in the USA]. IBSN 0 582 0 6701 4. Reprinted 1994, 1995, 1996, 1998. Printed in Chinese 2000.
• ROLLINSON H.R. 2007. Early Earth Systems: a geochemical approach. Blackwell Publishing, Oxford, UK. 296 pp. ISBN: 1405122552.

I am also interested in the Geology and Tectonics of Oman and co-edited the book:

• ROLLINSON, H.R., Searle, M.P., Abbasi, I., Al-Lazki, A.I. and Al-Kindi M.H., 2014. Tectonic Evolution of the Oman Mountains. Special Publication of the Geological society 392, 471 pp.

I have published extensively on the topic of chromite mineralisation in Oman, Greenland and Zimbabwe. Working with Dr Jacob Adetunji at the University of Derby and Dr Davide Lenaz at the University of Trieste we are studying the oxidation state of chromite using Mossbauer spectroscopy and single-crystal X-ray spectrometry.
