Title: Fluorescence of Acritarchs in Study of Marine Kerogen: ABSTRACT

Author(s): A. B. Reaugh, G. S. Bayliss

Article Type: Meeting abstract


Acritarchs, the organic-walled palynomorphs of algal affinities, exhibit strong fluorescence colors depending upon species type, stage of thermal maturity, and degree of oxidation.

This fluorescence readily enables identification of acritarchs in gross kerogen concentrates and provides a means of Previous HitdistinguishingTop acritarch fragments in poorly preserved kerogen assemblages.

Although acritarchs show similar fluorescence colors in an autochthonous assemblage, there may be minor differences as a result of different types and wall thicknesses. Similarily, the varying degrees of oxidation of individual palynomorphs can give differing colors.

Thick-walled marine algae also fluoresce but can be distinguished from acritarchs by the differences in intensity of the fluorescence colors.
