Early Cambrian microfossils from the cherts in carbonates of the Kuruktag area, the Tarim block
The basal Cambrian is characteristic for the appearance of small shelly fossils and acanthomorphic acritarchs with relatively small vesicles. In the Tarim Block (NW China) and South China, this microfossil ass...

Microfossils from nodular cherts in the Middle Ordovician Yijianfang Formation carbonates (Well YJ1X), Tarim Basin, China
Although the micropaleontology of Ordovician deep-sea cherts is relatively well documented, microfossil assemblages in Ordovician shallow-marine cherts are less well-known. Nodular cherts in the Middle Ordovic...

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...
