The relationship between the loess stratigraphy in the Vojvodina region of northern Serbia and the Saalian and Rissian Stage glaciations – a review [PDF]

open access: hybridBoreas
The regional loess stratigraphy in the Vojvodina region, in the southeastern Carpathian Basin, has often been successfully correlated to the global palaeoclimate. This is a quasi‐continuous sedimentary record that provides detailed environmental reconstruction during the last four glacial/interglacial cycles.

Sequence stratigraphy of the Upper Miocene Stage IVC in the Labuan-Paisley Syncline, northwest Sabah Basin [PDF]

open access: bronzeBulletin of the Geological Society of Malaysia, 1997
A sequence stratigraphic study of the Upper Miocene Stage IVe has been carried out in the Labuan-Paisley Syncline, Northwest Sabah Basin with the aim of identifying new hydrocarbon plays in the study area. The Stage IVe contains up to 4,000 m thick, clastic sediments deposited in coastal plain to bathyal environments probably between 8.2 Ma and 10.5 Ma

Stratigraphy and correlation of the Ururoan and Temaikan Stage (Lower‐Middle Jurassic, ?Sinemurian‐Callovian) sequences, New Zealand [PDF]

open access: bronzeJournal of the Royal Society of New Zealand, 2003
Abstract The biostratigraphy and chronostratigraphy of Ururoan, Temaikan, and earliest Heterian sequences from the Kawhia and Southland Regional Synclines are discussed and new chronostratigraphic divisions proposed. A new definition for the base of the Temaikan Stage is proposed, using the first appearance of either Belemnopsis deborahae or ...
