The table contains 40Ar / 39Ar dating information of mylonite samples from the Korean Peninsula. At first, the samples were separated by crushing → water bleaching → sieving → magnetic separation → specific gravity liquid separation, and then the single mineral dating samples such as biotite, amphibole and Muscovite were selected by hand under binocular lens. The experimental method is 40Ar / 39Ar dating. After pretreatment, the samples were irradiated in the "swimming pool reactor" of the Chinese Academy of atomic energy. The helix MC of the Institute of geology of the Chinese Academy of Geological Sciences was used to heat the samples in stages. The isoplot program was used to calculate the plateau age and the positive and negative isochrons. This data can provide data support for understanding the eastward extension of the Dabie Sulu orogenic belt on the Korean Peninsula.

File naming and required software

The data is stored in Excel format. The name of the document is "xxxxx-xx-A", where xxxxx-xx represents the sample number, A represents the abbreviation of sample mineral type, B represents biotite, am represents amphibole, and M represents muscovite.
