Upper holocene tephro-chronostratigraphy of Irazú Volcano, Costa Rica. [PDF]
Sci RepIrazú is one of the largest and most active volcanoes in Costa Rica. We present the tephro-chronostratigraphy of the last 2.6 ka of the Irazú volcano based on detailed field work and C14 radiometric dating, as well as a revision of the geological and ...

The chronostratigraphy of protoplanet Vesta [PDF]
Icarus, 2014 In this paper we present a time-stratigraphic scheme and geologic time scale for the protoplanet Vesta, based on global geologic mapping and other analyses of NASA Dawn spacecraft data, complemented by insights gained from laboratory studies of howardite–eucrite–diogenite (HED) meteorites and geophysical modeling.

A Database of Radiocarbon Dates for Palaeoenvironmental Research in Eastern Africa
Open Quaternary, 2016 Radiocarbon dating is one of the most widely available and applied techniques to develop Late Quaternary chronologies of many ecosystems and is, thus, utilized in Quaternary studies, archaeology, hydrology, geomorphology, palaeoanthropology ...

Chronostratigraphy of Barva and Poas Volcanoes, Volcanic Central Cordillera, Costa Rica
, 2018 The chronostratigraphy from >50,000 BP to the present was determined for the overlapping tephra deposits from Barva and Poas volcanoes, located 20 km north of San Jose, Costa Rica, using stratigraphic correlations supported by fourteen C14 ages.

The Upper Miocene of the Rostov Dome (Eastern Paratethys): Implication of the chronostratigraphy and bivalvia-based biostratigraphy [PDF]
Geološki Anali Balkanskoga Poluostrva, 2005 The Rostov Dome is located in the south of the Russian Platform. In the Late Miocene this area was embraced by the Eastern Paratethys. The implications of a recently developed Neogene chronostratigraphy to the studied area are discussed.
