Micro-Raman Spectroscopy of Selected Macerals of the Huminite Group: An Example from the Szczerców Lignite Deposit (Central Poland)
Lignite (ulminite reflectance Rr = 0.27%) from the Szczerców deposit (Central Poland) is dominated by huminite group macerals, containing a high proportion of attrinite and densinite. Densinite and ulminite are more abundant in small aromatic units than attrinite, which may result from their stronge...
