Ordovician series and stages in Chinese stratigraphy: steps toward a global usage
Alcheringa: An Australasian Journal of Palaeontology, 2001The first Chinese Ordovician series was erected by Lee & Chao (1924). Since then, many regional Ordovician series and stage names have been established and mostly published in Chinese. The present study is a review of these regional units with a discussion of their definitions and correlation to the international standard. Among them, the Ichang series,

The stratigraphy of the Callovian and Oxfordian stages (Middle-Upper Jurassic) in northern Scotland [PDF]
Synopsis Outcrops of Middle-Upper Jurassic rocks in northern Scotland are restricted to two sedimentary basins. In the east exposures at Brora (Sutherland) and Balintore (Ross-shire) are part of the Moray Firth basin. In the west major exposures at Staffin and in Strathaird (Isle of Skye) belong to the Minch basin.

The Zaisan Basin is a unique geological structure that preserves a most complete sedimentary archive of late Mesozoic through most of the Cenozoic era. A century of studies brought very rich data on the stratigraphy and geological history of the Zaisan sedimentary sequence.

The Otekaike Limestone Trig Z sequence in southeastern South Island, New Zealand, is the type section for the local Waitakian Stage, and contains the Duntroonian/ Waitakian Stage boundary, previously thought equivalent to the Oligocene/Miocene Epoch ...

SUMMARY The recent suggestion that no warm-stage deposits have yet been found separating glacial sediments in lowland southern and eastern Britain is shown to be incorrect. At Morston, on the coast of north Norfolk, an ancient beach succession with a temperate pollen assemblage rests upon till closely comparable with the Marly Drift, usually ...

The history of definition of the Aptian-Albian boundary is reviewed with particular reference to the ammonite schemes of Brinkmann (1937), Breistroffer (1947), Casey (1961a, 1996, 1999), Kemper (1982), Owen (1996, 1999), and Ruffell & Owen (1995).
