The sequence covers the last 10,000 years. \r\n\r\nThe geochemical data-set consists of elemental (Si, K, Ti, Al, Rb, Mn, Ca, Sr, Fe, Y, Ga, C and N), and carbon isotope variability through time.\r\n\r\nThe molecular composition was retrieved through FTIR-ATR analysis and contains information about organic and inorganic compounds. The biogenic data is based on grass phytolith analysis conducted at selected depths. The pyrogenic data file contains information about combustion residues in the sequence, based on pyrolysis-GC-MS analysis. The chronological framework was retrieved through AMS radiocarbon dating of seven bulk samples. \r\n\r\nThe results from this data-set was used to infer hydrological, grassland composition and wildfire variability throughout the last 10,000 years in the study area (see reference below).
