Angkor dating radiocarbon america webcam girl

This study presents preliminary results of research on pre-Angkorian canals near the ancient settlement of Angkor Borei in the southern Mekong delta of southern Cambodia.

The canals have been mapped by aerial photograph interpretation and investigated in the field by hand auger drilling of two canal traces and trenching of one of these.

The apparent demise of the canal coincides with a major change in land-use signalled in pollen and diatom data from Angkor Borei, but this change cannot be taken to indicate de-population of the region.

It is assumed that the amount of radioactive carbon left in the sample indicates how old it is. It is based on several assumptions, one of which is false.

PY - 2008/12Y1 - 2008/12N2 - In the Angkor monuments of Cambodia, pieces of wood remain (as head frames of doorways, crossbeams, ceiling boards, etc.) in the following 8 monuments: Bakong, Lolei, Baksei Chamkrong, North Khleang, Angkor Wat, Banteay Kdei, Bayon, and Gates of Angkor Thom.

Accelerator mass spectrometry (AMS) radiocarbon dating carried out on 15 wood samples collected from the above 8 monuments revealed that most of the wood samples are original, except for the head frame of a doorway in Baksei Chamkrong, the ceiling boards in the northwest tower, and a crossbeam with pivot hole in the southwest tower of the Inner Gallery of Angkor Wat.

The 14C age for the head frame of a doorway in the inner wall under the central tower of North Khleang supports the hypothesis that the inner walls are additions from a later period.
