Evidence for ancient halophiles? Testing biomarker syngeneity of evaporites from Neoproterozoic and Cambrian strata

Schinteie, Richard; Brocks, Jochen

Description

Molecular fossils from evaporites can provide significant insights into the biotic composition of ancient hypersaline ecosystems. However, hydrocarbon contamination can mask the true nature of this composition and potentially result in misleading interpretations. In this study, drill core samples of Neoproterozoic- and Cambrian-age dolomite, anhydrite and halite from the Amadeus Basin in central Australia contain distinctive and varied hydrocarbon signatures. The results are consistent with...[Show more]
