INFLUENCE OF AIR PARCELS FROM NORTHERN AND SOUTHERN HEMISPHERES ON RADIOCARBON-BASED INCA CHRONOLOGY

Autor: Santiago Ancapichún, Jacek Pawlyta, Andrzej Z Rakowski, Dominika Sieczkowska

Publikováno v: Radiocarbon. 64:1431-1446

The chronology of Machu Picchu was traditionally associated with the period attributed to the reign of Pachacuti Inca Yupanqui. Within the scheme of the so-called “historical chronology”, proposed by John H. Rowe in 1945, the ascension to power o

This paper presents a compilation of atmospheric radiocarbon for the period 1950–2019, derived from atmospheric CO2 sampling and tree rings from clean-air sites. Following the approach taken by Hua et al. (2013), our revised and extended compilatio

ABSOLUTE DENDROCHRONOLOGICAL SCALE FOR PINE (PINUS SYLVESTRIS L.) FROM UJŚCIE (NW POLAND), DATED USING RAPID ATMOSPHERIC 14C CHANGES

Autor: Jacek Pawlyta, Damian Wiktorowski, Andrzej Z. Rakowski, Marek Krąpiec, Monika Bolka

Publikováno v: Radiocarbon. 63:1205-1214

Radiocarbon (14C) analyses are commonly used to determine the absolute age of floating tree-ring chronologies. At best, with the wiggle-matching method, a precision of 10 years could be achieved. For the early Middle Ages, this situation has been mar

Publikováno v: Radiocarbon. 63:1133-1148

According to the classical chronology of the Inca State, the ascension to power of Pachacuti Inca took place around AD 1438 and the construction of Machu Picchu began by AD 1450–1460. However, the improvement in the accuracy of radiocarbon (14C) da

A Tree-Ring chronology from Allerød–YD transition from Koźmin (Central Poland)

Autor: Elżbieta Szychowska-Krąpiec, Joanna Barniak, Damian Wiktorowski, Natalia Piotrowska, Adam Michczyński, Tomasz Goslar, Piotr Kittel, Andrzej Z. Rakowski, Marek Krąpiec, Danuta J. Michczyńska

Publikováno v: Geochronometria. 47:101-111

Subfossil trunks of pine (Pinus sylvestris L.) from the Late Weichselian were discovered in the site Koźmin in the Koło Basin, central Poland (Dzieduszyńska et al., 2014a). Another part of organic sediments with trunks was excavated in the frame o

Status of the AMS graphitization system in the dendrochronological laboratory at AGH-UST, Kraków

Autor: Marek Krąpiec, Andrzej Z. Rakowski, Alexander Cherkinsky, Damian Wiktorowski

Publikováno v: Geochronometria. 47:112-117

A new system for the preparation of graphite samples for radiocarbon (14C) measurement using an accelerator mass spectrometer (AMS) has been built in the Dendrochronological Laboratory at AGH-UST, Kraków. This system consists of three independent co

Publikováno v: Radiocarbon. 61:1327-1335

Miyake et al. (2012, 2013, 2014) described a sudden increase of radiocarbon (14C) concentration in annual tree rings of Japanese cedar (Cryptomeria japonica) and Hinoki cypress (Chamaecyparis obtusa) between AD 774 and 775 and between AD 993 and 994.
