Abstract

The temperature gradients have been measured in six bores in Nottinghamshire and in two in north Yorkshire. The heat flow at some of the Nottinghamshire bores is much larger than is usual. The largest is 2.87 × 10-6 cal./cm.2 sec. It is shown that this very local anomaly cannot be due to an excess of radioactivity or to igneous activity. An explanation is given depending on the flow of water from west to east over the Eakring anticline. The mean heat flow at the bores in Nottinghamshire is 2.24 × 10-6 cal./cm.2 sec. and of those in Yorkshire 1.16 ×-6. These results do not confirm the theoretical expectation that low-lying places will have a small heat flow.
