Holocene organic geochemical data from Borreguil de la Caldera (S Spain)

This dataset includes both bulk sediment organic data and biomarker data: total organic carbon (TOC), total nitrogen (TN), total hydrogen (TH), atomic hydrogen ? carbon ratio (H/C), atomic carbon - nitrogen ratio (C/N), carbon isotopic composition (13C), and nitrogen isotopic composition (15N) (measured by means of isotope-ratio mass spectrometry with a coupled elemental analyser, IRMS-EA), as well as n-alkane concentrations (from C18 to C37), including the total n-alkane concentration, the average change length (ACL), the portion aquatic (Paq), and the carbon preference index (CPI) (measured using gas chromatography with flame-ionization detection - GC-FID).

本数据集涵盖了大量的沉积物有机质数据以及生物标志物数据，包括总有机碳（TOC）、总氮（TN）、总氢（TH）、氢碳原子比（H/C）、碳氮原子比（C/N）、碳同位素组成（13C）和氮同位素组成（15N）（通过同位素比率质谱仪与元素分析仪联用，IRMS-EA）测量获得），以及C18至C37的n-烷烃浓度（包括总n-烷烃浓度、平均变化长度（ACL）、水生部分（Paq）和碳偏好指数（CPI）（使用气相色谱与火焰电离检测器联用，GC-FID）测得）。
