Stage boundaries, global stratigraphy, and the time scale: towards a simplification

open access: yesCarnets de Géologie, 2004
This paper examines four facets of stratigraphic terminology and usage considered faulty and proposes corrective measures. The four perfectible areas are: (1) The system of dual nomenclature requiring discrete terminologies for the superpositional and ...

The Triassic of Timor: Lithostratigraphy, chronostratigraphy and palaeogeography

open access: yesJournal of Asian Earth Sciences, 2009
The palaeontologically rich and lithologically diverse Triassic successions of Timor provide a key stratigraphic and palaeontological link between northwestern Australia and other terranes of former eastern Gondwana (present-day Southeast Asia). Timor is now located in the zone of collision between the northern margin of the Australian continent and ...

Micropalaeontology reveals the source of building materials for a defensive earthwork (English Civil War?) at Wallingford Castle, Oxfordshire [PDF]

open access: yes, 2010
Microfossils recovered from sediment used to construct a putative English Civil War defensive bastion at Wallingford Castle, south Oxfordshire, provide a biostratigraphical age of Cretaceous (earliest Cenomanian) basal M. mantelli Biozone. The rock used

Seismic stratigraphy and history of deep circulation and sediment drift development in Baffin Bay and the Labrador Sea [PDF]

open access: yes, 1989
Drilling results and seismic-reflection records at and across Ocean Drilling Program (ODP) Sites 645 (western Baffin Bay), 646, and 647 (Labrador Sea) provide important constraints on the history of deep-water circulation and sedimentation in response to
