Chronostratigraphy of Gran Canaria [PDF]

open access: gold, 1998
A chronostratigraphy of Miocene/Pliocene volcanism on Gran Canaria (Canary Islands) has been established by single- crystal 40Ar/39Ar laser dating of feldspar crystals from 58 samples of welded ignimbrites, lava flows, fallout tephra layers, and intrusive rocks.

The Anthropocene: Comparing Its Meaning in Geology (Chronostratigraphy) with Conceptual Approaches Arising in Other Disciplines

open access: yesEarth's Future, 2021
The term Anthropocene initially emerged from the Earth System science community in the early 2000s, denoting a concept that the Holocene Epoch has terminated as a consequence of human activities.

Toward a Robust Plio‐Pleistocene Chronostratigraphy for ODP Site 762 [PDF]

open access: bronzeGeophysical Research Letters, 2020
The advent of rapidly acquired proxy records provides paleoceanographers and paleoclimatologists with a wealth of high‐resolution data. These data are a boon for the community, as they enable millennial or even submillennial scale interpretation of past ...

Quaternary chronostratigraphy of south Spitsbergen

open access: goldPolar Research, 1987
Recent detailed investigations of Quaternary sediments in south Spitsbergen enabled us to choose several key areas in this region (Lindner et al. 1984, 1986; Butrym et al. 1987). Samples collected in these areas were thermoluminescence and radiocarbon dated, and applied for a chronostratigraphic scheme of the Quaternary for this part of Svalbard (Fig ...

The Upper Miocene of the Rostov Dome (Eastern Paratethys): Implication of the chronostratigraphy and bivalvia-based biostratigraphy [PDF]

open access: yesGeološki 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.

Quaternary chronostratigraphy - a review [PDF]

open access: yesBulletin of the Geological Society of Finland, 1992
Quaternary development is characterized by strong climatic fluctuations associated with repeated glacier expansions. Consequently the Quaternary chronostratigraphy is largely based on the dating of climatic fluctuations which have led to large-scale ...

Chronostratigraphy, Site Formation, and Palaeoenvironmental Context of Late Pleistocene and Holocene Occupations at Grassridge Rock Shelter (Eastern Cape, South Africa)

open access: gold, 2020
Grassridge rock shelter is located in the high elevation grassland foothills of the Stormberg Mountains in the Eastern Cape of South Africa. This places Grassridge at an important biogeoclimatic intersection between the Drakensberg Mountains, the South ...

A Revised Cenozoic Geochronology and Chronostratigraphy

open access: yes, 1995
Since the publication of our previous time scale (Berggren and others, 1985c = BKFV85) a large amount of new magneto- and biostratigraphic data and radioisotopic ages have become available. An evaluation of some of the key magnetobiostratigraphic calibration points used in BKFV85, as suggested by high precision 40Ar/39Ar dating (e.g., Montanari and ...

Upper holocene tephro-chronostratigraphy of Irazú Volcano, Costa Rica [PDF]

open access: yesScientific Reports
Irazú 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 ...
