Description
The deep-sea ferromanganese crust (DSFC) is not only an ideal archive for recording the history of the Earth’s evolution, but also a natural reservoir for rich in a variety of metal elements. As one of the most important cosmogenic nuclides, as well as an ideal indictor of natural events since Quaternary, 26Al has not been as widely used in chronological studies as 14C, 10Be etc., due to the influence of factors such as measurement sensitivity and 26Al in situ production. The survey and exploration of 26Al dating method to a typical deep-sea ferromanganese crust were re-conducted based on previous research. A crust with a more rational stratigraphic structure was selected, the experimental method was further optimized, background interfering nuclides were analyzed, and 10Be data were still used as a control. The final results show that the 26Al dating is feasible for application to deep-sea ferromanganese crusts.
