Facies Associations of Riphean Sedimentary Sequences

Lithology and Mineral Resources, 2002
Large-scale facies associations typical of intra- and pericratonic Riphean sections of the Volga–Ural region, western slope of the Urals, Timan–Pechora region, Kola Peninsula, outer and inner parts of the Siberian, North American, and Indian platforms are considered.

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.

On Aphebian stromatolites and Riphean stromatolite stratigraphy

Precambrian Research, 1977
Abstract New occurrences of typical Riphean stromatolite and microphytolite groups are reported and illustrated from typical Aphebian sequences in Canada. These include Minjaria, Colonnella, and Kussiella from the Mistassini Group of central Quebec, Gymnosolen, Jacutophyton garganicum, Minjaria, Colleniella, Kussiella, Tungussia, Lenia, Osagia, and ...

Riphean Petroleum Systems of The Western Part of Siberian Platform

Proceedings, 2008
After discoveries of large oil-and-gas fields within Yuribchen-Tokhoma Zone the Riphean deposits are considered as a promising object for an exploration. The rocks are quite widespread and probably have been deposited within several anisochronous basins.

Mineralogy and petrography of Riphean rocks in the Moscow graben

Lithology and Mineral Resources, 2000
Based on the study of Upper Precambrian rocks penetrated by the Pavlovskii Posad parametric borehole in the 1770–4780 m interval, the Riphean succession is underlain by quartzose sandstones. The aulacogen within the Moscow Syneclise was covered by sediments accumulated during the intense chemical weathering of a peneplain. Above the 3550 m level, Upper

Hydrocarbon Potential of Riphean-paleozoic Deposits of Taimyr

Proceedings, 2012
Regional 2D seismic explorations of enhanced depth were carried out at the beginning of XXI century for the first time. They allowed together with other geological-geophysical data fundamentally change the model of structure of Yenisey-Khatanga regional depression, Taimyr mountain area, Siberian Platform and Western-Siberian plate.

Approaches to Studies of Fractured Riphean Reservoirs, Kuyumba Oilfield

Proceedings, 2014
This work is related to the issues in focus of exploration of the opened fractured zones in the riphean deposits that are productive on the Kuyumba field. Studying of the core samples show several stages in fracture origin, one of those are mineralized and another are opened and good to be studied by this paper.
