in his seminal book on the historical periods of western attitudes toward death, philippe aries describes four consecutive periods through which these attitudes evolved and transformed. according to him, the historical attitudes of western cultures have passed through four major parts described above: “tamed death,” one’s own death,” “thy death,” and “forbidden death.” this paper, after explori...

Accurate chronology of climatic shifts is critical to understand the controls on landscape and species evolution. Unfortunately, direct dating continental climate change hindered by scarcity dateable terrestrial products evidencing shifts. Here we use ferruginous indurations from arid landscapes Nullarbor Plain in southern Australia constrain timing Plio-Pleistocene aridification realm. We pres...

Abstract. A new ice core was drilled in West Antarctica on Skytrain Ice Rise field season 2018/2019. This 651 m is one of the main targets WACSWAIN (WArm Climate Stability Antarctic sheet last INterglacial) project. present-day accumulation rate 13.5 cm w.e. yr−1 derived. Although project mainly aims to investigate interglacial (115–130 ka), a robust chronology period covering recent past neede...

The Golo River drains a steep catchment (average gradient of 30 m km?1, surface 1214 km2) in the northeast part Corsica Island, delivering sediments to Ligurian Sea. In this study, we review and revise geologic map constrain extent coastal alluvial plain formations their relative absolute chronology. To update each formation, performed geomorphologic analysis with DEMs satellite imagery data co...

Chang’E-5 is the first lunar sample return mission of China. The spacecraft was landed in northwest Procellarum KREEP Terrane (43.0576°N, 308.0839°E) on 1 December 2020 and returned 1731 g samples from a previously unvisited region. landing area has been proposed as one youngest mare basalt units Moon holds important information thermal evolution chronology. However, absolute model ages estimat...

Abstract Impact cratering on the Moon and derived size-frequency distribution functions of lunar impact craters are used to determine ages unsampled planetary surfaces across Solar System. Radiometric dating samples provides an absolute age baseline, however, crater-chronology for remain poorly constrained beyond 3.9 billion years. Here we present U–Pb geochronology phosphate minerals within sh...
