Geochemistry and thermolysis of flavonoids
Abstract:
The thermal and pH stability of selected flavonoids has been determined under simulated geologic conditions. Thermolytic rates and products for various regimes, as determined by gas chromatography-mass spectroscopy, indicate the potential usefulness of flavonoids as thermometric indicators in sediments. The parametric factors affecting flavonoid stability are used to geochemically characterize angiosperm "green leaves" (36 to 25 x 10(6) years old) from Succor Creek and indicate that these sediments have not experienced temperatures higher than 80 degrees C or extreme pH shifts (beyond the range 6.3 to 7.2) during postdepositional maturation.
