Curie point depth in Venezuela and the Eastern Caribbean
We estimate the Curie point depth (CPD) variations of Venezuela (continental crust, South American plate) and the Eastern Caribbean (oceanic crust, Caribbean Plate) by using spectral analysis of the magnetic anomalies, extracted from the 2010 Enhanced Magnetic Model (EMM2010), available at the National Oceanic and Atmospheric Administration (NOAA). To test the reliability of the spectral content of this model, for a small region, we compare he CPD derived from the EMM2010 against the one from aeromagnetic data. We also compile heat flow data from previous studies to correlate them with the CPD lateral variations. The estimations show that the CPD …

Heat Flow and Fluid Flux in Cascadia's Seismogenic Zone
The Cascadia Subduction Zone in the northeast Pacific has generated a large number of megathrust earthquakes and poses the greatest recognized seismic hazard to the northwestern United States. To learn more about the risks this subduction zone poses, scientists from Washington and Oregon conducted a research cruise in August aboard the R/V Atlantis to collect data that would estimate the thermal structure of the “fully locked zone” of the Cascadia megathrust fault. This locked zone resists the continuous motion of two tectonic plates as they collide, storing compressional energy that produces large megathrust earthquakes when released by the abrupt failure …

Characteristics of Heat Flow and Lithospheric Thermal Structure in the Junggar Basin, Northwestern China
Abstract Characteristics of present-day heat flow and thermal structure of lithosphere in basins are essential constraints to reveal the tectonic-thermal evolution process and to reconstruct thermal history of the basins, which are of great significance for research of basin dynamics and evaluation of petroleum resources. This work is based on 11 newly measured high-quality heat flow values from well-log temperature data in 102 boreholes, oil-test temperature data in over 400 new boreholes, and thermal conductivity data of 187 samples from 15 wells measured by optical scanning in the Junggar basin. Our purpose is to analyze features of heat flow and …
The thermal structure of Israel and the Dead Sea Fault
In this paper we analyze temperature data from all the available oil and water wells in Israel and compare the results with seismicity depth and with heat flux estimation from xenoliths. We show that the average heat flux in Israel is 40-45 mW/m(2), consistent with measurements of the Arabian Shield. A heat flux anomaly exists in Northern Israel and Jordan. This could be attributed to groundwater flow or young magmatic activity (similar to 100,000 years) that is common in this area. A higher heat flux exists in Southern Israel and Jordan, probably reflecting the opening of the Red Sea and …
Heat flow and gas hydrate saturation estimates from Andaman Sea, India
Gas hydrate was recovered in the Andaman Sea along the eastern coast of the Andaman Islands during the India National Gas Hydrate Program (NGHP) Expedition-01 at Site NGHP-01-17. Coring confirmed gas hydrate occurs predominantly in discrete volcanic ash layers. Pore water chemistry, electrical resistivity and P-wave velocity logs are used to estimate gas hydrate saturations at Site NGHP-01-17. Gas hydrate saturation estimated from chloride concentrations shows values up to similar to 85% of the pore space for distinct ash layers from similar to 270 m below seafloor to the base of gas hydrate stability zone (BGHSZ). Gas hydrate saturations estimated …
Heat flow measurements on the Lomonosov Ridge, Arctic Ocean
Heat flow was measured on the Lomonosov Ridge during the 5th Chinese National Arctic Expedition in 2012. To derive the time-temperature curve, resistivity data were transformed to temperature by the resistivitytemperature program. Direct reading and linear regression methods were used to calculate the equilibrium temperature, which were regressed against the depth of the probes in sediment to derive the geothermal gradient. Then, heat flow was calculated as the product of geothermal gradient and thermal conductivity of sediments. The heat flow values on the basis of the two methods were similar (i.e., 67.27 mW/m2 and 63.99 mW/m2, respectively). The results are …

Towards a de-carbonized energy system in north-eastern Morocco: Prospective geothermal resource
Geothermal data has been indicating promising potentialities in the north-eastern Morocco. This paper presents new temperature data, recently recorded in water boreholes located in the Berkane and Oujda areas. Generally, the observed temperature gradients are rather high. One hole near Berkane, revealed an average geothermal gradient of more than 110 degrees C/km at depths greater than 300 in. This result confirms the geothermal gradient estimated in a mining borehole located about 30 km west of the Berkane borehole, in which water temperature of 96 degrees C is reached at a depth of about 700 m. Such a high geothermal gradient, …

Thermal properties of sediments in southern Israel: a comprehensive data set for heat flow and geothermal energy studies
To decipher the thermal structure of the sedimentary veneer in southern Israel, new values of thermal conductivity and porosity as well as of the radiogenic heat budget are provided. Thermal conductivity is measured for lithotypes and scaled up for geological formations. The new data are higher than most of the previously measured values, in particular for sandstones and siltstones, whose mean values are 5.0 and 2.9 similar to W similar to m-1 similar to K-1. Mean values of the most abundant lithotypes, which are dolomites and limestones, are on the order of 4.1 and 2.7 similar to W similar to …

Temperature Profiles for the Continental and Oceanic Crust
Summary Fluctuating geothermal parameters such as heat flow, heat generation, and coefficient of the thermal conductivity are considered in wide ranges. Probable temperatures in the earth's crust for a number of cases and an interpretation of the geothermal gradient from recent laboratory data are given. The examples of reduction of seismic and thermal ambiguity are discussed.
