Thermal maturation of carbonaceous material from Mbuji-Mayi Supergroup (Kasai, Democratic Republic of Congo).

… The Mbuji-Mayi Supergroup is a sedimentary sequence in DRC unaffected by regional
metamorphism. It consists of two distinct successions: a lower, ~500 m thick siliciclastic
sequence of the BI Group and an upper, ~1000 m thick carbonate sequence with stromatolitic
build-ups and black shales of the BII Group directly overlain by basaltic lavas [1]. Radiometric
data suggest a Latest Meso- to Early Neoproterozoic age [2, 3, 4, and 5]. … Raman reflectance
(RmcRo %), which is also an index indicative of maturity [8], ranges from 1.05 to 2.55 …
