Molecular preservation of 1.88 Ga Gunflint organic microfossils as a function of temperature and mineralogy
Abstract
Thermal diagenesis is generally seen as detrimental to the preservation of organic biosignatures. Using synchrotron-based XANES data, Alleon et al.find preservation of the molecular signatures of organic microfossils from the 1.88 Ga Gunflint cherts.
