The sediment core Asea-1 was retrieved from the Asea Valley, Peloponnese Greece, in 2010 using a vibra corer. The upper 5 m were scanned at 0.5 cm resolution with non-destructive X-ray fluorescence (XRF) using a molybdenum X-ray source in an ITRAX core scanner. The topost 0.18 m are lacking. The raw data presented here is displayed as element counts per second (cps). The core sequence was analysed to reconstruct the environmental history and palaeoclimatic fluctuations in the area during the Late Holocene. Therefore, log-ratios and a principal component analysis on normalized counts were used.

This file displays the XRF data measured on core Asea-1. The core was scanned at 0.5 cm resolution with an ITRAX core scanner and the raw data presented here is displayed as element counts per second (cps). It was first used in Unkel et al. (2014).The archaeological periods indicated are explained in the article Seguin et al. (2020). All chemical elements are indicated in counts per second (cps). The last 3 columns PC1, PC2 and PC3 refer to the first three principal components of a Principal Component Analysis (likewise explained in detail in Seguin et al. 2020).
