Catalogue of geothermal data for the land area of the United Kingdom. Third revision: April 1987

A comprehensive geothermal database is essential for many aspects of geothermal research, including the modelling of sub-surface temperature fields and resource assessment. As part of the 1984-1987 geothermal programme BGS has maintained and expanded all aspects of the geothermal database, and the main components - temperature, heat flow, thermal conductivity and geochemistry - are briefly described here. A brief explanation of the modifications and extensions to the database is given in each of the sections 2 to 5. The results are presented as Tables 1-5. Table 1 gives the supplementary temperatures abstracted in the period 1984/87 in a form similar to that of Table I in the second revision (Burley, Edmunds and Gale 1984) and Table 2 gives a summary listing of all sites for which sub-surface temperature data are available. Table 3 summarises the thermal conductivity data, and Table 4 the UK heat flow data. The new geochemical data are listed in Table 5. This Catalogue uses the categories of temperature and heat flow data identified in the second revision, and a full description is not given here.
