A four stage evolution of the White Channel gravel: Implications for stratigraphy and palaeoclimates [PDF]
, 2014 Although the White Channel gravel (WCG) of the Klondike district, Yukon, contains gold placers which have been exploited for over a century, few sedimentological studies have been undertaken.

Integrated stratigraphy of the Waitakian‐Otaian Stage boundary stratotype, Early Miocene, New Zealand [PDF]
New Zealand Journal of Geology and Geophysics, 1999 Abstract The base of the type section of the Otaian Stage at Bluecliffs, South Canterbury, is recognised as the stratotype for the boundary between the Waitakian and Otaian Stages. Principal problems with the boundary are the restriction of existing bioevent proxies to shelf and upper slope environments and its uncertain age. These topics are addressed

Moscow University Bulletin. Series 4. Geology, 2020 The study of the paleocommunities of foraminifera of the reference section of the Paleogene-Neogene of the Kvachin Bay in Western Kamchatka made it possible, based on the qualitative composition and quantitative ratios of the species encountered, to identify 13 layers with foraminifera corresponding to certain section intervals and to establish their ...

Aspects of the stratigraphy and ammonite faunas of the Aalenian-Bajocian stages in Great Britain [PDF]
, 1980 A detailed stratigraphic revision of parts of the Aalenian-Bajocian Stages is undertaken. The status of the Sowerbyi zone is discussed and reasons given for its rejection and replacement by the Discites and Laeviuscula\ud Zones. The Sauzei Zone is redefined.

Marine Isotope Stage 11c in Europe: Recent advances in marine–terrestrial correlations and their implications for interglacial stratigraphy – a review [PDF]
BoreasThe interglacial known as MIS 11c (c. 426 000–396 000 years ago) receives intensive international interest because of its perceived role as an analogue for the current interglacial and its importance for understanding future climate change. Here we review the current understanding of the stratigraphy of this interglacial in Europe. This study considers
