All drilling and soil sampling campaigns were conducted in the framework of the “EarthShape” project (DFG SPP1803) from March 2019 to March 2020. Rock and soil samples consist of granitoid lithology that is weathered to different degrees.

We measured the concentration of in situ 10Be in quartz samples from soil samples and calculated denudation rates thereof. Furthermore, we applied a sequential extraction method to analyse meteoric 10Be and reactive 9Be; we also measured residual 9Be and parent bedrock 9Be concentrations. Using the concentration of meteoric 10Be, we calculated the inventory assuming exponential decrease with depth. Finally, we calculated the depositional flux using the in situ 10Be denudation rate and the 10Be(meteoric)/9Be isotope ratio. From reactive 9Be, we calculated the fraction of reactive and dissolved 9Be that we interpret as weathering indicator.

All samples are indicated with a IGSN (International Generic Sample Number) which is a global unique sample identifier. These IGSNs are provided in the data tables and are linked to a short data description in the internet.
The DFG Priority Program 1803 "EarthShape - Earth Surface Shaping by Biota" (2016-2022; https://www.earthshape.net/) explored between scientific disciplines and includes geoscientists and biologists to study from different viewpoints the complex question how microorganisms, animals, and plants influence the shape and development of the Earth’s surface over time scales from the present-day to the young geologic past. All study sites are located in the north-to-south trending Coastal Cordillera mountains of Chile, South America. These sites span from the Atacama Desert in the north to the Araucaria forests approximately 1300 km to the south. The site selection contains a large ecological and climate gradient ranging from very dry to humid climate conditions.
