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.

Heat flow and heat production in Zambia: Evidence for lithospheric thinning in central Africa
Final report, intermediate-depth, hole No. 1-78-U1, Socorro Prospect, New Mexico
During the period May 19, 1977 to July 22, 1977, fourteen heat flow boreholes were completed on the Socorro Prospect, New Mexico. Rock types encountered ranged from unconsolidated Quaternary alluvium to dense volcanic rocks. Depths of the holes were from 60 to 440 feet with an average total depth of 288 feet. Geothermal gradients from the fourteen boreholes ranged from 0.32 to 7.58 F/100 ft. Thermal conductivity values of 3.6 to 7.5 mcal/cm-sec C were obtained from a total of 76 samples of drill cuttings. Individual heat flow values range from 0.3 to 5.4 HFU (1 HFU-1 microcal/cmsup 2-sec). The …

Relationships between terrestrial heat flow and structure of the earth crust in Poland
The authors compared the distribution of the temperature gradients and heat flow with some known parameters of the earth crust in Poland. They found a dependence of the above geothermal parameters on the thickness of the sedimentary cover. The dependence on the depth of Moho discontinuity also exists, but it seems less strict. There is probably also a relationship between thermal anomalies and neotectonics, but because of the scarcity of data these questions still remain open.

A geothermal study of the Mid-Atlantic Ridge near 37°N
A suite of 101 well-navigated heat-flow stations was used to investigate lithospheric cooling on the Mid-Atlantic Ridge near 37°N. Measurements in two topographic depressions marking the intersection of transform faults with axes of sea-floor spreading show evidence of hydrothermal circulation in basement rocks. One of these depressions appears to have been subjected to a recent bottom-water temperature change which severely biases the heat-flow data. Some of the evidence suggests that transform faults are more permeable than other regions of the ocean crust and therefore may cool much faster.We also measured the heat flow in rift mountains extending from 10 to …
Heat-flow measurements on the Northern Apennine arc
The mechanisms of heat transfer through the floor of the Indian Ocean
The results of temperature loggings in numerous holes were used to calculate geothermal gradients and to estimate heat flow. On the basis of these data a preliminary heat flow map of Spain is proposed., The mean land heat flow value amounts to 82 mWm−2 in the Iberian peninsula and reaches 99 mWm−2 in the surrounding marine areas, which in both cases is considerably higher than the mean European heat flow. There is a negative correlation between heat flow and crustal thickness. The heat flow generally increases from the central part of the peninsula (82 mWm−2) toward the Mediterranean coast (95 …

The Structure of the Crust-Mantle Boundary Beneath North America and Europe as Derived from Explosion Seismology
Summary Geophysical studies of the earth's crust and upper mantle during the past 20 years have revealed detailed information on the structure of the crust-mantle boundary in Europe and North America. Mainly, on the basis of explosion seismology the elastic properties of the crust-mantle boundary can be described as follows: the depth to the M discontinuity beneath continents ranges from 20 to 60 km, the velocity of P waves within the uppermost mantle beneath the M discontinuity varies between 7.2 and 8.5 km/s, and the crustmantle boundary is a discontinuity of the first order only in a few cases. (It …

Heat Flow in the United States and the Thermal Regime of the Crust
Summary A contour map of heat flow based on 625 observations now available in the conterminous United States shows new detail. Sub-provinces of exceptionally high heat flow (>2.5 HFU (1 HFU = 10−6 cal/cm2 s)) in the western states are beginning to emerge as regional features, but their boundaries are still largely unknown. The ‘Battle Mountain High', previously described in north central Nevada, probably extends northeastward to Utah and Idaho and westward almost to California. With the eastern Snake River Plain, a region that probably has large convective loss, it could form a zone of exceptionally high heat loss that …
