Literature Review
The Global Heat Flow Database (GHFDB) is committed to maintaining the highest standards of data quality. To achieve this, we have implemented a rigorous literature review process that ensures all datasets are thoroughly vetted before being made publicly available.

Geothermal anomalies along the Rio Grande rift in New Mexico
Geohydrologic data from the Jemez Mountains and vicinity, north-central New Mexico
The Jemez Hountains volcanic region, on the west margin of the Rio Grande rift in north-central New Hexico, is the site of studies whose objective is power development using geothermal heat. This report summarizes geohydrologic data obtained to provide background information relative to the geothermal exploration and to investigate the usefulness of hydrology in assessment of the geothermal resource. Eleven tables present chemical, temperature, discharge, and other data for springs, wells, and streams. Accompanying figures show locations of the data points and present temperature profiles and geophysical logs for selected wells.
Heat flow, radiogenic heat production and crustal temperatures in England and Wales
New values of heat flow are reported from thirty-one sites in England and Wales. Thermal conductivity of core material from fourteen of the sites and thermal gradients, obtained over several hundred metres, were used to calculate reliable heat flow values for these localities. At the remaining seventeen sites the value of heat flow is calculated from thermal gradient measurements alone, assigning conductivity on the basis of stratigraphic logs. An average heat flow of 1.40 μcal/cm2s is computed for the region, based upon 40 sites. Slightly higher than average heat flow may characterise the Lincolnshire sedimentary basin, within which temperatures may …
Geothermal gradients and heat flow in northern Thailand
Final Report: Intermediate-Depth Hole No. 1-78-U1
During the period May 28, 1978 to June 30, 1978, an intermediate depth heat flow borehole (1-78-Ul) was completed on the Socorro Prospect, New Mexico. Rock types encountered in the hole ranged from unconsolidated Quaternary alluvium to clays and dense volcanic rocks. Depth of the hole was 1360 feet with the major drilling problems being sticky clays and hard rock. The geothermal gradient measured in this borehole was 2.46 F/100 ft with an average thermal conductivity of 5.9 mcal/cm-sec- C. The calculated heat flow value is 2.7 HFU (1 HFU = 1 microcal/cmsup 2-sec). The linearity of the gradient for …
