This list covers part of the samples measured at the Radiocarbon Dating Laboratory, Physics Department, University of Bern since summer 1962. Two low-level counters, as described by Houtermans and Oeschger (1958), with incorporated anticoincidence are used. Each sample is measured in both counters. The CO2 from the sample is converted to methane by pumping a (CO2 + H2)-mixture at a pressure below 1 atm over a Ru-catalyst at 200°C.

The University

The radiocarbon laboratory, operated by the Department of Physics and the University Museum at the University of Pennsylvania, is concentrating its analyses in four fields of archaeology: the Middle East, Middle America, South America, and the Arctic. It is the policy of the laboratory to publish radiocarbon dates only in groups from one specific field after checks and rechecks of related materials result in a certain measure of internal consistency (Ralph 1955: 149-51; Coon and Ralph 1955: 921-2).

Set Up

The radiocarbon dating laboratory was set up during 1972 and 1973 with financial support of the FKFO (Fonds voor Kollektief Fundamenteel Onderzoek) Belgium, to enable us to place Upper Pleistocene and Holocene sediments in their correct stratigraphic position. Dating of samples began in the middle of 1974.

The People

At the beginning of June, the ICRC made a further appeal to governments and National Red Cross Societies for their material and financial support to continue its humanitarian activities for the victims of the conflicts in Africa. It requested, for the period from 1 July to 31 December,the sum of 35.8 million Swiss francs, equivalent to about 5 million Swiss francs per month. The ICRC warned prospective donors that, if no help was swiftly forthcoming, it would be compelled to reduce the activities of its delegations in various African countries, and that the consequences would mean considerable hardship for the people in need of ICRC aid.

This paper provides an analysis of radiocarbon dates acquired during earlier and recent field seasons at the Keatley Creek site, southern British Columbia. Results indicate that early occupations predating 1900 cal. B.P. occurred, but were not likely associated with population aggregation and large housepits. The aggregated village appears to have emerged by approximately 1700 cal. B.P. and was abandoned at approximately 800 cal. B.P. A break in the occupational sequence is recognized at 1450-1350 cal. B.P. and one other short break may have occurred shortly after 1250 cal. B.P. Peak socioeconomic complexity appears to have been achieved between 1350 and 800 cal B.P. Climatic warming may have provided a selective environment favoring population aggregation and intensification during this time. The final abandonment of the Keatley Creek village appears to have been part of a regional phenomenon suggesting the possibility that climatic factors were important in this case as well.

Age Range

We report preliminary results of a long-term systematic study intended to gather paleoclimatic records from precisely dated speleothems. The research project is limited to speleothems deposited in caves of the Cracow-Wieluń Upland, the largest and best-explored karst region in Poland, covering ca. 2900 km2 with >1000 caves. Speleothem samples were selected from collections of the Geological Museum of the Academy of Mining and Metallurgy in Cracow. Radiocarbon dates of these samples from ca. 45–20 ka bp almost exactly coincide with age range of the Interplenivistulian. A break in speleothem formation between ca. 20 and 10 ka bp may be interpreted as a result of serious climatic deterioration associated with the maximum extent of the last glaciation. We observed differences among 14C, U/Th and AAR dating results. Changes of δ13C and δ18O in speleothems that grew between ca. 30 and 20 ka bp may be interpreted as changes of paleoclimatic conditions.
