Extracts of bled resin from Azorella compacta, of the Azorelloideae family from the Andes (>4000 m), were analyzed by gas chromatography-mass spectrometry. The mass spectra of the dominant compounds of the resin and its hydrogenation products were do

The lipid/resin components of Laretia compacta were characterized by GC-MS and CSIA. The lipid components consist of n-alkanes, n-alkanoic acids and n-alkanols all with low carbon number maxima and high CPI values. The resin components are comprised

Extensive petroleum shows have been sampled from the seabed of Guaymas Basin. These petroleums were generated at depth by hydrothermal activity from immature sedimentary organic matter and migrated to the sea floor. There the heavy ends solodify due

Our increasing knowledge of the geochemical processes of present-day sedimentation conditions provides a basis for evaluating the role of oxic and anoxic sedimentary environments. In particular, there are organic geochemical parameters, such as lipid
