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.
Sporinite (average 50 vol%) and vitrinite (average 23 vol%) are dominating (Table 2).
One specimen has a petrographic composition typical of a cannel shale, in which sporinite is the most abundant organic constituent; the other is characterized by Botryococcus-alginite bodies typical of a boghead coal.

A relatively small percentage of kerogen type II (sporinite, liptodetrinite) was observed, while coaly kerogen was very sparse (< 4 vol%).
