User:Taxelson/QUB - Northern Ireland first century AD
The Oak chronology for Ireland is, based on the QUB-material, possible to build continuously and with good quality down to about 100 AD, and before that remains a rather tiny tail down to 13 BC (The oldest samlpe is QUB:Q218 from Mill Lough). According to the Late Roman gap-problem an indisputable link between the Irish AD-chronology and the English Roman time complex would be very welcome and of great value. Unfortunately the link, so far, is too weak to confirm the date accepted for Roman complex. Here meta data and analyzes of the old tail of the Irish QUB data may be gathered. The sites in QUB forming the old end of the present time Irish chronology are Allistragh, Ballinderry, Balloo, Mill Lough and Teeshan. The best correlation values towards the English complex has been found when the old end tail of each mean sample, where just one or two single samples are available, are truncated. (corr(P2Y)=0.35, overlap=172, T=4.8).
Allistragh, AD 39 - 337 (>2 samples from AD 97) (natural, bog oak?)
Ballinderry, AD 25 - 618 (>2 samples from AD 110) meta data missing, but possibly anthropogenic remains (and likely the "Ballinderry" in Antrim county). It is unlikely that it refers to some of the more famous crannogs, Ballinderry I and II in central Ireland, as nothing indicates another provenience of the Ballinderry collection than for the other four.
Balloo, AD 17 - 312 (>2 samples from AD 52) (probably bog oaks, found reused in a rather modern building)
Mill Lough, 13 BC - AD 611 (>2 samples from AD 37) (natural, bog oak?)
Teeshan, AD 82 - 581 (>2 samples from AD 144) Crannog
