The Baykonurian glaciohorizon of the Late Vendian

Stratigraphy and Geological Correlation, 2009
Glacial deposits occurring close to the Vendian-Cambrian boundary were discovered long ago in several regions of Asia and West Africa. New data of recent years confirm earlier observation and specify age constraints of these deposits. In certain sections, glacial sediments rest on beds with the Upper Vendian fossils (Vendotaenia sp., Sabellidites ...

TOWARDS STAGE SUBDIVISION OF THE VENDIAN

Геология и геофизика, 2023
Путь к ярусному расчленению венда должен лежать через составление полного сводного геологического разреза этого отрезка земной коры - последовательности геологических тел, каждое из которых отражает определенное состояние экосистем. В качестве основы ярусной шкалы венда предлагается использовать сводный разрез венда Сибирской платформы ...

Vendian Hydrogeochemistry of the Siberian Platform

Russian Geology and Geophysics, 2021
Abstract —The Vendian deposits of the Siberian Platform are represented by four regional horizons (from bottom to top): Nepa, Vilyuchan, Tira, and Danilovka. The TDS of brines in the Nepa and Vilyuchan horizons varies from 170.3 to 470.1 g/L, and the TDS in the overlying Tira and Danilovka horizons, from 84.6 to 583.1 g/L.
