Improved age estimates for key Late Quaternary European tephra horizons in the RESET lattice
The research project ‘Response of Humans to Abrupt Environmental Transitions’ (RESET) used tephra layers to tie together and synchronise the chronologies of stratigraphic records at archaeological and environmental sites. With the increasing importance of tephra as chronological markers in sedimentary sequences, both in this project and more generally, comes a requirement to have good estimates...
متن کاملThe RESET tephra database and associated analytical tools
An open-access database has been set up to support the research project studying the ‘Response of Humans to Abrupt Environmental Transitions’ (RESET). The main methodology underlying this project was to use tephra layers to tie together and synchronise the chronologies of stratigraphic records at archaeological and environmental sites. The database has information on occurrences, and chemical c...
متن کاملEnvironmental history and tephrostratigraphy at Carp Lake, southwestern Columbia Basin, Washington, USA
Sediment cores from Carp Lake provide a pollen record of the last ca. 125,000 years that helps disclose vegetational and climatic conditions from the present day to the previous interglaciation (120–133 ka). The core also contained 15 tephra layers, which were characterised by electron-microprobe analysis of volcanic glass shards. Identified tephra include Mount St. Helens Ye, 3.69 ka; Mazama a...
متن کاملArchaeological Excavations and Finding Antiques by European Travelers and Orientalists during Qajar Era
The history of new and scientific archaeological researches in Iran mainly dates back to the Qajar period. Although the history of European Oriental studies in Iran has exceeded the Qajar era, however, until the aforementioned period, scientific archeology in Iran did not have much meaning and European officials and Orientalists studies in Iran mainly focused on the identification of Iranian an...
متن کاملTephra beds in deep-sea cores off northern New Zealand: implications for the history of Taupo Volcanic Zone, Mayor Island and White Island volcanoes
Twenty piston cores were collected from water depths of ∼650–3300 m from offshore Bay of Plenty, North Island, New Zealand. They contain tephra from 11 Okataina Volcanic Centre and 4 Taupo Volcanic Centre rhyolite eruptions during the last ∼50 kyr that produce a tephrostratigraphic framework across the tectonically and volcanically complex region of southern Havre Trough, Alderman Trough and th...
