FACIAL UNCONFORMITIES AND FACIAL SERIES IN THE SEQUENCE STRATIGRAPHY
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
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

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.

Boninite and boninite-series volcanics in northern Zambales ophiolite: doubly vergent subduction initiation along Philippine Sea plate margins [PDF]
A key component of subduction initiation rock suites is boninite, a high-magnesium andesite that is uniquely predominant in western Pacific forearc terranes and in select Tethyan ophiolites such as Oman and Troodos. We report, for the first time, the

The stratigraphy and origin of the portaskaig boulder bed series (Dalradian) [PDF]
AbstractThe late Pre‐Cambrian Portaskaig Boulder Bed Series shows a very uniform sequence for some 600 km along the Caledonian strike, from Connemara on the west coast of Ireland to Aberdeenshire in Scotland. The Series, which is divided into four groups of beds, comprises numerous individual boulder beds separated by stratified sediments.

Global Series and Stages for the Ordovician System: A Progress Report
There is no global standard set of chronostratigraphic/geochronologic subdivisions for the Ordovician System/Period. British series/epochs are often used as de facto nomenclature on stratigraphic correlation charts and geologic time scales. However, they
