Diagenetic stability of sporopollenin opens door to study deep-time palynomorphs

Watson, JS, Fraser, WT & Sephton, MA (2012) Formation of a polyalkyl macromolecule from the hydrolysable component within sporopollenin during heating/pyrolysis experiments with Lycopodium spores. Journal of Analytical & Applied Pyrolysis 95, 138-144. doi:10.1016/j.bbr.2011.03.031

This article demonstrates the stability window of sporopollenin under laboratory simulated diagenetic conditions. We show that sporopollenin is resistant to chemical alteration when subject to low-to-moderate diagenetic conditions, maintaining its original aliphatic:phenolic co-polymer configuration. Under the most extreme of conditions tested here we show that the co-polymer configuration begins to defunctionalise and reploymerise to be replaced in-situ by a predominantly aliphatic polymeric structure, including aliphatic components significantly shorter than originally were present in the starting material. The outcome of this study shows that fossil sporopollenin may still retain its original chemical composition, even after being subjected to diagenesis. Such a finding opens the door for investigating deeper time chemical composition of sporopollenin and environmentally-influenced variations in sporopollenin structure, beyond that currently achieved.
