The North African desert margin is considered one of the areas most sensitive to future climate changes. Improved knowledge about Holocene climatic variability and environmental responses on millennial to centennial scale will help to refine scenarios related to future climate changes. This data set presents 198 bulk sample-based Spectro Xepos XRF measurements. Bulk samples from the recovered cores were analysed using a Spectro Xepos X-ray fluorescence instrument. For the XRF sample preparation, air-dried bulk material (4 g) was sieved (2 mm). The sample was then homogenised using a Retsch vibrating mill MM 200. Pressed pellets were produced with a Vaneox press at 20 t for 2 min. The measurements were carried out in a He atmosphere.
