“…It seems probable that the good state of preservation of the resin components may well be another example of the anti-oxidant effects of verdigris which we have previously noticed and commented on in the case of fatty acids [76] and sterols [77]. 6 . EXPERIMENTAL…”

The botanical sources and chemical compositions are reviewed of natural resins used, Of likely to have been used, in the fabrication of objects of art and archaeology. They fall into two main chemical groups: those containing diterpenoids-from the order Coniferales and from the Leguminosae family-and those containing triterpenoids from several families of broad-leaved trees. Their chemical compositions, although liable to varying degrees of change with time and exposure, permit them to be identified more or less precisely in favourable cases. Examples of such identifications are described, mostly of conifer resins, using gaschromatography.

“…Gas chromatography/mass spectrometry of the samples revealed that most of the cyclic hydrocarbons identified (Appendix; Fig. 6) are either hopanoids or fernenes from bacterial sources (Ourisson et al, 1979;Brassell and Eglinton, 1983) or terpenoids probably derived from terrestrial higher plants (Kulshreshtha et al, 1972). The mass spectrum of two unidentified C 30 triterpanes are shown in Figures 7A and 7C.…”

Using methods of analysis from organic geochemistry and organic petrography, we investigated six Pliocene to Maestrichtian samples from DSDP Site 612 and five Pliocene to Eocene samples from DSDP Site 613 for the quantity, type, and thermal maturity of organic matter.At both sites, organic carbon content is low in the Eocene samples (0.10 to 0.20%) and relatively high in the Pliocene/Miocene samples (0.87 to 1.15%). The Maestrichtian samples from Site 612 contain about 0.6% organic carbon. The organic matter is predominantly terrigenous, as indicated by low hydrogen index values from Rock-Eval pyrolysis and the dominance of long-chain wax alkanes in the extractable hydrocarbons. The organic matter is at a low level of thermal maturity; measured vitrinite reflectance values were between 0.27 and 0.44%.
