A laboratory and field-monitoring experiment on the ability of anti-slide piles to prevent buckling failures in bedding slopes
Buckling failure is a special form of a landslide, and it has been little debated in the literature so far. There have been few studies conducted on this type of slope failure, and the corresponding reinforcem...

Mechanical properties of clay reinforced with Bermuda grass root under drying–wetting cycles
The mechanical properties of the clay slope gradually weaken after the drying–wetting (D–W) cycles, which increases the possibility of landslides. Therefore, the variation of mechanical properties of the root–...

The Yudomski event and subsequent decline: new evidence from δ34S data of lower and middle Cambrian evaporites in the Tarim Basin, western China
Marine evaporitic sulfates (gypsum and anhydrite) can record ancient seawater sulfur isotopic data; however, these records are scarce and widely dispersed owing to both restricted environments in which they fo...

Stromatolites in Middle Ordovician carbonate–evaporite sequences and their carbon and sulfur isotopes stratigraphy, Ordos Basin, northwestern China
At the present day, stromatolites are very rare and limited to high-salinity settings. However, abundant and variable stromatolite fossils occur in thick evaporite sequences, the Middle Ordovician Majiagou For...
