... microbialites are useful biosignatures when filaments are no longer preserved, but have typically been observed within stromatolites. This study describes bubble-associated fenestrae within oncoids from the early Cambrian Bayan Gol Formation of Mongolia. Fenestrae appear in mm-scale micritic laminae which...

... of the Tsagaan Oloom Fm. are between the Khasagty-Nuru ridge and the Dzabkhan River (Fig.  29.1 ). The geology of the Dzabkhan platform was first described by Bezzibetsev (1986) , who divided the stratigraphy into three formations (the Dzabkhan, Tsagaan Oloom and Bayan Gol). Subsequent work focused on the early...
