Signatures of the Involvement of Microorganisms in the Formation of Nodular Monazite (Kularite), Republic of Sakha (Yakutia), Russia

Data indicating the important role of microorganisms in the formation of nodular monazite (NM) (kularite) of the Kular Range, Republic of Sakha (Yakutia), are presented. The NM contains microorganisms (cyanobacteria) replaced by REE-bearing phosphate (monazite) in the form of stromatolitic microedif...

Zusammenfassung:Data indicating the important role of microorganisms in the formation of nodular monazite (NM) (kularite) of the Kular Range, Republic of Sakha (Yakutia), are presented. The NM contains microorganisms (cyanobacteria) replaced by REE-bearing phosphate (monazite) in the form of stromatolitic microedifices, as well as framboidal Fe sulfides in monazite. The C org isotopic composition of kularite corresponds to biogenic carbon: the δ 13 С values vary from –22.2 to –22.3‰.
