“…µ-Raman spectroscopy, µ-FTIR spectroscopy, synchrotron radiation-based µ-FTIR and pyrolysis-gas chromatography/mass spectrometry have been used ( at least some acritarch genera. Following a µ-FTIR study, an unusual large acritarch species from the Givetian of Libya is composed of an algaenan similar to that from Botryococcus braunii (Steemans et al 2009a). The fate of post-Precambrian acritarch biopolymers altered due to thermal maturation has never been elucidated.…”
