Data for: Major and trace element characterization of Oceanic Anoxic Event 1d (OAE 1d): Insight from the Umbria-Marche Basin, central Italy

Table A: Major and trace element content and nannofossil indices data for the analyzed samples from the Monte Petrano section. Table B: Major and trace element content and nannofossil indices data for the analyzed samples from Le Brecce section. Figure C: Stratigraphic distribution of lithogenic conservative elements (Si, Ti, K, Fe, Rb, Zr) versus Al at the Monte Petrano section. For the sake of readability, the Si/Al axis is cropped. Black-to-dark grey shale samples are indicated with MP following the code used in Figure 3. The vertical line in the graphs represents average shale (AS) composition according to Wedepohl (1971, 1991). Figure D: Stratigraphic distribution of lithogenic conservative elements (Si, Ti, K, Fe, Rb, Zr) versus Al at Le Brecce section. For the sake of readability, the Si/Al axis is cropped. Black-to-dark grey shale samples are indicated with BR following the code used in Figure 3. The vertical line in the graphs represents average shale (AS) composition according to Wedepohl (1971, 1991). Figure E: Crossplots reporting Al-normalized redox-sensitive element composition with weak- (Cu, Ni, Cr, Co) and strong- (Mo, U, V, Zn, Pb) euxinic affinity versus TOC for the black-to-dark grey shale layers at Monte Petrano and Le Brecce sections. Redox thresholds follow Algeo and Maynard (2004).
