The Origin of Coalsor marsh. Coal formation has been a rare event in geological time, the principal eras in Europe and North America having been about 300 m. and 50–100m. years B.P. Major changes in plant anatomy took place between these two periods..The results of a recent multi-disciplinary study of profiles of five

The Nature and Origins of Coal Maceralsinite maceral groups are discussed and compared to the corresponding liptinite macerals. The importance of separating macerals is considered, and some recent results using the density gradient centrifugation method of maceral separation is briefly reviewed. It is demonstrated that vitrinites are com

Estimating Thermophysical Properties of Coal Liquids Using NMR Spectraters, average molecular structures and functional group concentrations can all be calculated based on NMR data. The NMR data can find much broader application, however, than merely characterizing structure. This paper reviews some of the basic methods for applying NMR to the problem of property esti
