Additional Information

The Suget layer, named in Xini Village in 1952, includes this formation and the overlying, Qigebulak Fm, Xiaoerbulake Fm, Yuertusi Fm, Awatag Fm and other formations. (later, people aften confused The Suget layer with the Bulaque Formation in Sugai). In 1957, Zhang Zhenhua, Gao Zhenjia and others re-subdivided and defined the lower red sandstone and named it the Sugaiteobulake Fm, which is still in use today.
