Paleowaters in the Cambrian-Vendian (Ediacaran)aquifer system of Baltic Basin - isotopic and Geochemical evolution since Late Pleistocene

, 2022
<p>An overview of the status and origin of groundwaters in the Shallowly buried marginal part of the Cambrian-Vendian (Edicaran) confined aquifer of the Baltic Basin, which is characterised by fresh and isotopically depleted 18 δ O composition of ...

Palaeogroundwater of glacial origin in the Cambrian-Vendian aquifer of northern Estonia

, 2001
A strongly depleted stable isotope composition, absence of 3H and a low radiocarbon concentration are the main indicators of glacial origin of groundwater in the Cambrian-Vendian aquifer in northern Estonia.

THE ROOM FOR THE VENDIAN IN THE INTERNATIONAL CHRONOSTRATIGRAPHIC CHART [PDF]

Геология и геофизика, 2015
Abstract The Vendian was proposed by B.S. Sokolov as a stratigraphic subdivision comprising the last of the Proterozoic glacial periods (the Laplandian Glaciation) and the overlying strata delineated by a full stratigraphic range of fossil soft-bodied organisms. For over three decades the Vendian had been an informal part of the Standard

Age determination of the Vendian intrusions in the polar Urals

, 2000
The Precambrian basement beneath the Pechora Basin of northern Russia is known from deep (up to approx. 4.5 km) drill holes to be largely composed of Neoproterozoic successions, variously deformed and metamorphosed and intruded by magmatic suites of ...

Carbon and strontium isotope record on the vendian-tommotian transition in the NW Argentina [PDF]

, 2001
Carbonates of the Las Tienditas Fm., Salta province, recorded the Vendian-Tommotian transition in the top of this carbonate sequence, while carbonates of La Laja Fm., San Juan, recorded this transition next to the base of the Formation. C, 87Sr/86Sr, Si,

A re-examination of the nama-type Vendian organism Rangea schneiderhoehni [PDF]

, 2005
The need to re-examine Rangea has been motivated by two factors: first, by the recent progress in the understanding of three-dimensional mouldic preservation of Vendian fossils, and second, by discoveries of this taxon outside Gondwana albeit in the same

The advent of the Phanerozoic world: Vendian stratigraphy, environmental change, and evolution

, 1992
The Vendian interval (ca. 610–540 Ma) links Proterozoic and Phanerozoic worlds of sharply contrasting character. Despite decades of study, the nature of this transition remains unclear, in part because of our limited ability to correlate Vendian ...
