Intensity of Chemical Weathering in Late Precambrian: New Data on the Riphean Stratotype (Southern Ural)

Стратиграфия, 2023
The values of Ni/Co, La/Sc, and Th/Cr (indicators of the composition of rock complexes eroded in paleowatersheds) and the values of CIA, Rb/Al, K/Al and K/Rb (indicators of the intensity of chemical weathering on land), typical for fine-grained clastic rocks of the Riphean of the Southern Urals were compared to the data given in the publication “Long ...

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 ...

Late Riphean Sedimentation in the Central Russian Aulacogen

Lithology and Mineral Resources, 2003
Result of the analysis of combined structural, facies, mineralogical, and micropaleontological data suggest that the formation of the Central Russian Aulacogen was related to the evolution of a major strike-slip system in the Late Riphean on the Russian Plate.

New insights into the nature of the Late Riphean Eosolenides

Precambrian Research, 2009
Abstract Studies of a morphologically diverse population of Eosolenides, organic-walled macrofossils from the Upper Mesoproterozoic (1015–1025 Ma) Lakhanda Group of southeastern Siberia, suggest that these elongate fossils may be remains of soft-bodied organisms having tube-grade organization.

Late Riphean age of the crystalline basement of the carbonate cover of the Dzabkhan microcontinent

Stratigraphy and Geological Correlation, 2015
The Dzabkhan microcontinent was earlier considered as a fragment of an ancient craton in the structure of the Central Asian Orogenic Belt. Deposits of the Tsagaan Oloom Formation were included in the shelf zone, under the assumption that they were related to the regional unconformity between the Early-Late Precambrian crystal formations.

Late Riphean Borisikha ophiolite (Yenisei Ridge): U-Pb zircon age and tectonic setting

Russian Geology and Geophysics, 2008
Abstract The Borisikha ophiolite, composed of serpentinites and amphibolites, is an extension of the Isakovka ophiolite belt in the near-Yenisei part of the Yenisei Ridge. It is a slightly disturbed ∼3.5 km thick fragment of the ophiolite association; its crustal part is composed of metamorphosed wehrlite, troctolite, and gabbro ...
