Application of geochemical analysis in the research of chemical fossils
Havelcová, Martina ; Sýkorová, Ivana ; Trejtnarová, Hana
Biomarkers (also termed chemical fossils) are specific organic compounds in geological samples which are derived from biochemical precursors by reductive or oxidative alteration processes. Chemical structures of biomarkers can be related back to the original compounds and utilized as indicators of biogenic, paleoenvironmental and geochemical processes. Examples of identified biomarkers in several studied coals, sediments, and wood fossils remnants are presented.
