Three groups of paleomagnetic data of the Sangdanlin Formation in the Saga area in the Tibetan Plateau, summaried from the paleomagnetic studies of Yuan et al. (2021) and Meng.et al. (2023)

The previous paleomagneitc data of Yuan et al. (2021) and Meng et al. (2023) from the Sangdanlin Formation in the Saga area were reanalyzed. The datasets were divided into three groups based ont the variation of paleo-inclination. The data of three groups were used for constraining the rapid fore-arc and back-arc extensions of the southeastern Lhasa Terrane during the Middle Paleocene。

Yuan等人（2021）和Meng等人（2023）此前发表的萨迦地区桑单林组古地磁数据（paleomagnetic data）被重新分析。根据古倾角（paleo-inclination）的变化，数据集被划分为三组。这三组数据被用于约束中古新世时期拉萨地块东南部快速的弧前与弧后伸展作用。
