Birmingham University Radiocarbon Dates IV
Measurements have continued with both the 1 L and 6 L counters. Results are not corrected for C 13 fractionation. Errors quoted refer only to the standard deviation calculated from a statistical analysis of sample and background count rates and the Libby half-life of 5570 ± 30 yr. Pretreatment has been continued as described previously (Shotton, Blundell, and Williams, 1969)
Birmingham University Radiocarbon Dates III
Measurements have continued with the 6 L counter. A counter of similar design but with 1 L volume has recently been brought into operation. Despite replacement of the teflon parts, the 1.5 L Oeschger-type counter has not worked consistently and has not been used for dating. Results are not corrected for δ C 13 . Errors quoted refer only to the standard deviation calculated from a statistical analysis of count rates and the Libby half-life of 5570…
Birmingham University Radiocarbon Dates II
Measurements have continued with the 6 L counter which has proved reliable at pressures as high as 2.6 atm and as low as 0.3 atm. It has now been enclosed in a double ring of 27 geiger tubes which has reduced the background count to 10 cpm at 2 atm. So far, we have had no success with the 1.5 L Oeschger-type proportional counter. Failure to obtain steady readings is probably due to continued outgassing from the teflon insulation. All insulating p…
Birmingham University Radiocarbon Dates I
A radiocarbon laboratory has been set up to assist with the Pleistocene research undertaken in the Geology Department at Birmingham and has been designed for the measurement of ages of geological material up to at least 50,000 yr old. Construction began in May, 1965 and routine dating commenced in October, 1966. This is carried out using a CH 4 proportional counter
The palaeomagnetism of some igneous rocks from Antarctica
A century ago geologists first began to consider the possibility of large lateral shifts of the continents. Reconstructions of the ancient positions of the continents have been proposed at various times since to try to explain past climatic zones, faunal distributions, similar orogenic sequences and structural trends on adjacent continents, and many other detailed geological events. Prominent amongst the hypotheses is that generally known as the …
