Stratigraphic distribution of paleoproductivity (Ex-SiO₂, Cu/Al, and Ni/Al), terrigenous influx (Al₂O₃+K₂O+Na₂O+TiO₂, Zr), paleoredox (Th/U, Mo_EF, and U_EF), and δ¹³C_org with TOC content in wells (a) A-038-B/94-N-08, (b) B-023-K/94-O-05, and (c) B-003-K/94-O-12. Legends indicate simplified 6 lithofacies, which are Mh (homogeneous mudstone), Ml (laminated mudstone), Mlb (black laminated mudstone), Mpf (papery fractured mudstone), Fl (laminated siltstone), and Fb (bioturbated fine siltstone).
