Calculated heat flow for the Ensenada region, Baja California, Mexico
<p>Due to the scarcity of heat flow data in the region of Ensenada, Baja California (Mexico), the present study calculated them using the silica geothermometer technique. The average heat flow value determined was 123.33 ± 35.57 mW m<sup>–2</sup> (2.95 ± 0.85 HFU). Four zones within the study area, related to the main fault systems of the region, were found to have high hydrothermal activity. The potential use of geothermal resources in the area is feasible as it is considered a low geothermal system with water temperature values, above the static water level, that vary from 30ºC to 108ºC.</p>
Downhole temperature, radiogenic heat production, and heat flow from the CRP-3 drillhole, Victoria Land Basin, Antarctica
Heat flow in the Vøring Basin, Mid-Norwegian Shelf
In situ temperature and heat flow were determined in 1994 at 159 sites, grouped into 66 clusters between latitude 65° N and 67°30’ N at water depths from 669 m to 1464 m. The mean of all cluster heat-flow measurements conducted in this survey was 58.5 mW m−2, with a standard error of ±4.40 mW m−2. The mean heat flow from IKU well data for the Trøndelag Platform is 56.2±6.65 mW m−2. Shorter wavelength heat-flow variations appear to be controlled structurally and can be explained by sedimentation and thermal refraction effects. High heat flow associated with faulted structural highs such …
Three deep Alpine-permafrost boreholes in Svalbard and Scandinavia
The presence and thermal character of permafrost reflect past and present surface energy balances plus the heat flux from the Earth's interior. Analysis of permafrost ground temperatures constitutes a key research tool for detecting thermal anomalies caused by twentieth-century warming. Three deep boreholes in alpine permafrost were drilled in Svalbard and Scandinavia and form part of the latitudinal transect of mountain permafrost boreholes through the mountains of Europe established under the EU PACE (Permafrost and Climate in Europe) project. The northernmost borehole in the transect, at Janssonhaugen (depth 102 m), western Svalbard (78 degrees 10 ' 46 "N, 16 " …
Heat‐flow data in western Victoria
New heat-flow data have been obtained in western Victoria at Horsham (89.8 +/- 7.3 mW m(-2)) and Warracknabeal (97.0 +/- 8.7 mW m(-2)). The results are significantly less than previous values obtained at Stawell and Castlemaine and consequently crustal models based on rapid cooling of high-level melt emplacements require revision. More general models based on mid-crustal detachments or underplating mechanisms do not require the preservation of a specific spatial anomaly and consequently remain unaffected. Previous inconsistencies between surface heat flow and surface heat production are eliminated if the new data are substituted for the previous Stawell and Castlemaine data.

Heat flow, sediment and pore fluid chemistry, and hydrothermal circulation on the east flank of Alarcon Ridge, Gulf of California
New seismic, heat flow, sediment and pore fluid geochemistry data from the east flank of Alarcon Ridge. at the mouth of the Gulf of California, provide evidence for vigorous hydrothermal circulation within young oceanic crust formed at a moderate-rate spreading center. Data and samples were collected 9-20 km from the ridge axis to assess the hydrologic state of 0.30-0.65 Ma seafloor. Conductive heat now values are 15-55% of that input at the base of the lithosphere. Heat flow is highest near the center of a sediment-covered trough, and lowest along the trough margins, suggesting that trough-bounding faults and basement exposures …
Geotermal'nye issledovanija v Pechorskom more (Geothermal Studies in the Pechora Sea )
In cruise 13 of R/V Akademik Sergei Vavilov in the Pechora Sea, six heat flow measurements were performed ranging from 50 to 75 mW/m(2). Deep heat flow in the Pechora Sea was calculated equal to 45 mW/m(2), which is confirmed by the results of the geological and geophysical studies and corresponds to the Middle Baikal age of the basement. A model of the structure of the lithosphere in the Pechora Sea is suggested. The total thickness of the lithosphere in the basin (190 km) determined from the geothermal data agrees well with that in the transition zones from the continent …
Lithosphere thermal structure and evolution of the Transylvanian Depression - insights from new geothermal measurements and modelling results
The surface heat flow density pattern of the Transylvanian Depression (TD) represents a marked high amplitude short wavelength low in a region of elevated heat flow. Detailed temperature-depth profiles obtained by continuous temperature logging, combined with a finite element modelling of topographic and fluid flow effects, support the conclusion that the observed thermal gradient in the TD truly represents the rate of heat loss of the subsurface. The surface heat flux is 30 mW m(-2) in the centre of the depression, increasing to about 60 mW m(-2) at margins. Climatic correction is of the order of 2-10 mW m(-2) depending …
Gas hydrate stability and the assessment of heat flow through continental margins
A prominent feature across some continental margins is a bottom-simulating reflector (BSR). This seismic reflection generally coincides with the depth predicted for the base of the gas hydrate stability field. Because the occurrence of gas hydrates is controlled by temperature and pressure conditions, it has been suggested that BSRs mark an isotherm and they have therefore been used to estimate the heat flow through continental margins: crucial parameters are the temperature at BSR depth and at the seafloor and the thermal conductivity structure between the BSR and the seabed. However, very often the required parameters are not available and therefore …
Terrestrial heat flow at Hirabayashi on Awaji Island, south-west Japan
Temperature-depth relationships based on log data from the Los Azufres geothermal field, Mexico
Equilibrium temperatures based on log data acquired during drilling slops in the Los Azufres geothermal held were used to study the relationship between temperature, depth and conductive heat flow that differentiate production from non-production areas. Temperature and thermal conductivity data from 62 geothermal wells were analyzed, displaying temperature-depth, gradient-depth, and ternary temperature-gradient-depth plots. In the ternary plot, the production wells of Los Azufres are located near the temperature vertex, where normalized temperatures are over 0.50 units, or where the temperature gradient is over 165 degreesC/km. In addition, the temperature data were used to estimate the depth at which 600 degreesC …
Thermal regime and petroleum systems in Junggar basin, northwest China
The conversion of organic matter into oil and gas depends upon temperature and time, and the study of thermal maturation of oil-source rocks in a petroleum system is of importance for formation of a petroleum system. Based on the temperature data from 196 wells and thermal conductivity measurements of 90 core samples, altogether 35 heat flow data are obtained in the Junggar basin. The results show that the Junggar basin is a relatively "cold" basin at present, with a mean temperature gradient and heat flow of 21 degreesC/km and 42mW/m(2), respectively. Thermal history reconstructed from vitrinite reflectance data indicates that …
Thermal history and tectonic subsidence of the Bohai Basin, northern China: a Cenozoic rifted and local pull-apart basin
The Bohai Basin is a part of the larger Bohai Bay Basin, a Cenozoic rifted intraplate basin. Heat flow measurements show that the Bohai Basin is characterized by present-day heat flow varying between 53 and 74 mW/m(2) with a mean of 63 mW/m(2). However, thermal history analyses derived from vitrinite reflectance (VR) and apatite fission track (AFT) data, indicate that tertiary cooling took place following a period of much higher paleo-heat flow (70-90 mW/m(2)) prior to similar to 25 million years to the present. Furthermore, tectonic subsidence analysis reveals that the Bohai Basin experienced episodic sub-rifting processes from the Eocene …
Compilation of heat flow data in the China continental area (3rd edition)
Terrestrial heat flow is the direct surface indication of the thermal process in the Earth's interior. It provides important information for geological, geophysical and geodynamical considerations. Since 1988, compilation of heat flow data have been regularly performed for 6 times in the continental area of China. The data from the first and the second compilations were reported as the 1st and 2nd editions, while the data from the later compilations were no more presented but the statistic results. Based on the sixth compilation of heat flow,this paper presents, as the 3rd edition,the 450 new heat flow data since the 2nd …
