The component variation of terrigenous organic matter and the sum of vitrinite, inertinite, sporinite, resinite, cutinite, fluorinite, and alginite (the sum of lamalginite and telalginite, Table 2) are plotted respectively in Figure 2c and Figure 3c-d.

The kerogen mainly consists of degraded alginite with a characteristic laminated microtexture (lamalginite), rarely of telalginite.
The low-ash coal seams were mainly formed in the freshwater paleoenvironment in the low-lying mire and the high-ash coal seams were primarily formed in the fluvio-lacustrine environment, the source of organic matter in coal seams being mostly conifers with little alginite supply [20].
Microscopic studies for selected oil shale samples (Table 2) define an organic matter assemblage consisting predominantly of alginite and amorphous material [23] which shows apparently a higher proportion of type I kerogen relative to the inferred proportion from Rock-Eval data and especially [S.
