Variations of the Eocene climate reflected in the isotopic composition of fossil resins from the Northwest Territories, Canada

Middle Eocene conifer resins have been analyzed for their C and H isotopic compositions, as well as spectral characteristics using FTIR. The resins were recovered from an unlithified peat sequence that forms part of the infill of the Giraffe kimberlite crater in the Lac de Gras field, Northwest Terr...

Description
Summary:Middle Eocene conifer resins have been analyzed for their C and H isotopic compositions, as well as spectral characteristics using FTIR. The resins were recovered from an unlithified peat sequence that forms part of the infill of the Giraffe kimberlite crater in the Lac de Gras field, Northwest Territories, Canada. Based on the presence of well-preserved macrofossils and FTIR spectra of fossil and modern resins, it is believed that the fossil resins were produced by Metasequoia glyptostroboides. R. Tappert, A.
