Fungal remains from the Late Riphean

Paleontological Journal, 2006
The paper describes organic remains of one billion years old from the Lakhanda microbiota of the Uchur-Maya Region of southeastern Siberia. The microfossils were discovered on organic sapropelic films. The preserved morphological characters and some developmental stages of the ancient organisms, which are fixed in fossil state, suggest that some of ...

Gabbro-peridotite sills of the Late Riphean Dovyren plutonic complex (northern Baikal area, Russia)

Russian Geology and Geophysics, 2018
Abstract We report data on the geology, mineralogy, petrography, and chemistry of 733 Ma gabbro-peridotite sills from the Late Riphean Dovyren plutonic complex. Thick sills were differentiated into plagiolherzolite to olivine gabbronorite compositions by fractional crystallization of the K–Na series high-Mg low-alkali low-Ti picritic ...
