Sequence stratigraphy, chemostratigraphy and facies analysis of Cambrian Series 2 – Series 3 boundary strata in northwestern Scotland [PDF]

open access: yesGeological Magazine, 2016
Globally, the Series 2 – Series 3 boundary of the Cambrian System coincides with a major carbon isotope excursion, sea-level changes and trilobite extinctions.

FACIAL UNCONFORMITIES AND FACIAL SERIES IN THE SEQUENCE STRATIGRAPHY

open access: diamondИзвестия высших учебных заведений: Нефть и газ, 2019
The sequence stratigraphy is currently, on the one hand, a leading approach in the study of the internal structure of sedimentary basins, on the other hand, a creatively developing discipline, the conceptual basis of which is being developed. The concept

BILOZERSKA SERIES OF THE UKRAINIAN SHIELD: PROBLEMS OF STRATIGRAPHY AND CORRELATION

open access: diamondGeological Journal, 2023
The article discusses the problematic issues of the geological structure of the Bilozersky synclinorium of the Ukrainian Shield, its stratigraphic structure, formation composition and absolute age of the rock associations that compose it. The interrelationships of interregional correlation of the Bilozerska and Kryvyi Rih series of the Ukrainian Shield

Introduction to the “Circum-Arctic Palynological Event Stratigraphy” (CAPE) series of papers

open access: bronzeAtlantic Geology, 2021
Palynomorphs are one of the few groups of fossils that provide biostratigraphic control in marine to nonmarine rocks and can be applied as proxies for paleoenvironmental and paleoclimatic interpretations. Their utility is enhanced by their microscopic size, which is usually less than 200 micrometres; they are thus easily recovered from small rock ...

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Implications of an integrated late Ediacaran to early Cambrian stratigraphy of the Siberian Platform, Russia

open access: yesGSA Bulletin, 2023
The transition from the terminal Ediacaran to early Cambrian (ca. 550−530 Ma) witnessed both the decline of Ediacaran-type soft-bodied and skeletal biota and the rapid diversification of Cambrian-type skeletal biota, which dominate the Terreneuvian (ca ...
