Cosmogenic nuclides: dating of old continental sediments in arid environments (D01)

点击翻译按钮获取中文摘要

This projects targets are (i) Developing extraterrestrial cosmogenic 10Be and 53Mn as a method to obtain terrestrial ages of interplanetary dust particles (IDPs) and micrometeorites extracted from fine-grained sediments (clay pan-deposits; atmospherically deposited gypsum dust), (ii) Develop and apply 10Be/21Ne-burial dating of coarse grained sediments (pebble layers in pan-sediments) (iii) Develop cosmogenic 21,22Ne to date near-surface occurrences of halite (halite = rocksalt, NaCl). Expected recoverable ages for sediments are ~ 1 to 22 Ma and ~ 0.5 to 10 Ma, for 53Mn and 10Be/21Ne-burial dating, respectively. There are no upper age limits for 21,22Ne.
