of exinite and vitrinite with the broad Lorentz 1 lines. Intensities (I) of the broad Gauss and the narrow Lorentz 3 lines of exinite and vitrinite changes with temperature according to the Curie law (I = Cm). The existence of thermally excited multiplet states was not stated for inertinite. The two groups of paramagnetic centres of inertinite with Lorentz 2 and Lorentz 3 lines obey the Curie law.

of hopanes and higher carbon preference index (CPI) values (in-C22 to n-C3o) show significant bacterial contributions in samples characterized by high values of tissue preservation index (TPI). The C31 a~ (22S/ 22S+22R) hopane and C29 aaa (20S/20S+20R) sterane ratios show least variation through the
An energy-dispersive x-ray fluorescence method for the direct, simultaneous determination of major and minor elements in coatings is described . The method relies on the back-scatter/fundamental parameter concept and provides a general solution to matrix problems . The method has been implemented an
