Subproject A02 focuses on the reconstruction of precipitation and vegetation changes of the Atacama Desert since the Miocene/Pliocene, their drivers and spatial heterogeneities. Therefore, a continuous deep-drilling record from the Paranal clay pan in the Coastal Cordillera of the southern CRC focus area will be investigated for sedimentological, mineralogical, geochemical, and ecological variations. This record shall close crucial gaps in the existing precipitation history of the Atacama and may expand it back to the postulated onset of hyperaridity during the Miocene. The research in the Atacama Desert will be complemented by a site survey to the Namib Desert to identify potential long-term climate records for the 3rd CRC phase.

子项目A02的重点是重建中新世/上新世以来阿塔卡马沙漠的降水和植被变化及其驱动因素和空间异质性。因此，将对CRC南部重点区域沿海科迪勒拉的Paranal粘土盘的连续深钻记录进行研究，以了解沉积学、矿物学、地球化学和生态变化。这一记录将填补阿塔卡马现有降水历史中的关键空白，并可能将其扩展到中新世期间假定的极度干旱开始。阿塔卡马沙漠的研究将得到纳米布沙漠现场调查的补充，以确定第三CRC阶段的潜在长期气候记录。
