C and Sr isotope chemostratigraphy of Vendian–Lower Cambrian carbonate sequences in the central Siberian Platform

Russian Geology and Geophysics, 2018
We propose a detailed δ13C curve for the Vendian and Lower Cambrian (Tommotian) strata of the central Siberian Platform. Two positive carbon isotope excursions identified near the base of the Yuryakh Formation (up to 5.5‰) and in the lower Bilir ...

Chapter 12 Pre-Vendian history

Geological Society, London, Memoirs, 1997
It so happens that rocks of Vendian age are extensive and are well exposed in Svalbard. This applies especially to early Vendian, i.e. Varanger, with two distinctive glacial horizons as are treated in the Chapter 13. The Early Varanger (Smalfjord) episode can be correlated in most sections and so provides a reference horizon which serves approximately ...

New Vendian Metazoa with Colonial Organization

Paleontological Journal
A new organism with colonial organization, Olgunia bondarenkoae gen. et sp. nov., of sponge or coelenterate grade, is described from the Vendian deposits of the South-Eastern White Sea region. The new genus is characterized by a modular pattern and coordinated growth of neighboring individuals arranged in a fan-shape. The new genus has a combination of

Chapter 13 Vendian History

Geological Society, London, Memoirs, 1997
The Vendian Period, the latest Precambrian division, and the earliest division in which several Phanerozoic methods of correlation can be applied, is a convenient time division for Svalbard. It is separated from the earlier history in which correlation has uncertainties of tens of millions of years if not more.

Vendian strata in their type area

Geological Magazine, 1987
AbstractIn the Eastern European region Vendian strata are divisible into two complexes: the lower one, only locally developed, is composed of alternating tillites, volcanics, sandy–clay rocks and dolomites; and the upper one, of alternating sandstone, siltstone, and mudstone strata with medusoid fauna, resting transgressively on the lower complex and ...
