✦ Synopsis

97101575 A geochemical study of macerals from a Miocene lignite and an Eocene bituminous coal, Indonesia Stankiewicz. B. A. el ul. 0%. Geochem.. 1996, 24, (S), 531-545. Maceral concentrates from a Miocene lignite and an Eocene high-volatile bituminous-carbon coal from Southeastern Kalimantan. Indonesia were subjected to optical and chemical studies using pyrolysis, optical, electron microprobe and FTIR techniques. The results showed that differences in the pyrolysis products between the huminite and vitrinite samples reflect hoth maturation-related and paleobotanical differences. Data from the electron microprobe and Fourier transform IR spectrometry strongly support the results obtained by Py-GC-MS and microscopy.
