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).表A：蒙特佩特拉诺（Monte Petrano）剖面分析样品的常量与微量元素含量及超微化石（nannofossil）指标数据。 表B：莱布雷切（Le Brecce）剖面分析样品的常量与微量元素含量及超微化石指标数据。 图C：蒙特佩特拉诺剖面中陆源保守元素（Si、Ti、K、Fe、Rb、Zr）相对于Al的地层分布。为便于阅读，Si/Al轴已做裁剪。按照图3所用编码规则，黑至深灰色页岩样品以MP标注。图中垂直线代表Wedepohl（1971、1991）提出的页岩平均组成（average shale, AS）。 图D：莱布雷切剖面中陆源保守元素（Si、Ti、K、Fe、Rb、Zr）相对于Al的地层分布。为便于阅读，Si/Al轴已做裁剪。按照图3所用编码规则，黑至深灰色页岩样品以BR标注。图中垂直线代表Wedepohl（1971、1991）提出的页岩平均组成（average shale, AS）。 图E：针对蒙特佩特拉诺与莱布雷切剖面的黑至深灰色页岩层，绘制了以Al标准化的氧化还原敏感元素相对于总有机碳（TOC）的交叉图，其中Cu、Ni、Cr、Co属于弱缺氧硫化（euxinic）亲和性组，Mo、U、V、Zn、Pb属于强缺氧硫化（euxinic）亲和性组。该研究所用氧化还原阈值遵循Algeo与Maynard（2004）的标准。
