In order to establish the chemical relationship between the liptinitic maceral suberinite and its recent counterpart, an inventory of the constituents of isolated outer bark tissue (periderm) of five extant angiosperm species was made. Samples were a

Information on the type and amount of refratoryy biopolymers produced by plants is still insufficient. The aim of the present work was to determine the chemical (structural) composition of spruce cuticles as a source material for humification. Intact

Morphologically well preserved fossilized cuticles of Symplocos hallensis of Eocene age from Geiseltal (Germany) and isolated cuticles from its “extant relative” Symplocos paniculata have been studied in order to determine the possible impact of

Forest soil organic matter contains a refractory alkyl-carbon component of unknown structure and composition. Soil samples obtained from different types of forest humus and from litter-bag experiments were examined by the complementary techniques of

The impact of the variations in the chemical composition of higher vascular plant cuticles on their fossil record is usually not considered in paleobotanical and, more particularly, taphonomic studies. Here we address the subject with reference to th

Abstract Geochemical techniques have been applied to a complex reservoir in Yemen in order to better understand its compartmentalization and filling history. Such information is of significant importance for effective reservoir management and determi

Abstract In an offshore Abu Dhabi field, two main reservoirs are produced commingled. Monitoring the production contribution from each reservoir was previously achieved through either Production Logging or Selective Production Tests. This paper prese

The kerogen of a sample of Estonian Kukersite (Ordovician) was examined by spectroscopic (solid state 13C NMR, FTIR) and pyrolytic (“off-line”, flash) methods. This revealed an important contribution of long, linear alkyl chains in Kukersite kero

This paper investigates to what extent the chemical constituents of plant cuticles (waxes and cutin) can survive diagenesis. Recent and fossil plant cuticles were analyzed by means of Curie point pyrolysis-gas chromatography and Curie point pyrolysis
