Terrestrial heat flow in North Central United States

Heat flow from deep boreholes on two island arcs

Heat flow was determined for deep boreholes at four sites on Amchitka Island, Alaska, and at one site near the northern central coast of Mindanao Island, the Philippines. Temperatures at all Amchitka sites were affected by vertical water movement, but portions of all temperature profiles were suitable for heat-flow determinations. Measured heat flow increases with depth at Amchitka. If allowance is made for a post-glacial increase in the mean surface temperature of the island, an equilibrium heat flow of 1.3 ?cal/cm2 sec results. At the Mindanao site, two independent determinations of heat flow over intervals of contrasting thermal conductivity agree, …

Heat flow along the candelaro fault — gargano headland (Italy)

The Gargano headland corresponds to a broad horst, which has been subjected to a slow raising after the Cretaceous. The geothermal gradients observed along the Candelaro fault in a surrounding zone of the headland, together with laboratory determinations of the thermal conductivity of rocks, show the existence of a high heat flow. This may be connected with both regional and local events, such as Moho discontinuity raising, magmatic intrusion, raising of groundwaters, and local variations in thermal conductivity.

Heat flow, temperature, and electrical conductivity of the crust and upper mantle in the U.S.S.R

A review of new heat flow values for regions of the U.S.S.R. is given. The temperature values corresponding to the different heat flow values from 0.5 to 2.0 HFU and the different thickness of the continental crust which are observed for the U.S.S.R. territory are constructed. The reliability of the magnetotelluric investigations for some regions of the U.S.S.R. territory is discussed. Using the laboratory data on the energy activations and electrical conductivity of olivinites for temperature range of 500°–1,200° C the models of electrical conductivity distributions in the upper mantle are constructed on the basis of temperature curves on the …

The Earth's crust and heat flow in Fossa Bradanica, southern Italy

A detailed study has been made of the Fossa Bradanica by means of seven shallow boreholes drilled in the clays. The observed gradients together with the results of in-situ thermal conductivity measurements indicate the heat flow as being between 0.4 and 2.2 μcal./cm2 ·sec. The influence of geographic and geological factors is discussed. The results obtained are not incompatible with crustal structures indicated by other geophysical methods.

Heat flow studies in the Godavari Valley (India)

Heat flow at six places in the Godavari Gondwana Basin of India are presented in this paper. These are based on measurements in boreholes of depths of 190–310 m. Heat flow values at Bellampalli (1.06), in the centre of the valley and at Mailaram (1.10), which is in Archean gneisses and schists bordering the Gondwana sediments, are normal. Heat flow increases from Chelpur to Pasra from 1.25 to 2.01, at the southwestern edge of the central portion of the valley. Heat flow at Chintalapudi and Aswaraopet in the southern part of the valley is high (2.22 and 2.49). Heat flow …

Heat flow at Damua and Mohapani, Satpura Gondwana basin, India

Terrestrial heat flow has been evaluated from measurements in two bore holes upto 475 and 380 meters depth, at Damua and Mohapani, in Satpura Gondwana basin in the central part of the Peninsular shield of India. The values obtained are1.46 ± 0.2and1.18 ± 0.13 μcal/cm2 sec respectively. These values are higher than those reported earlier for the northwestern part of the Godavari valley which is a sedimentary trough filled with Gondwana sediments. The values are typical of continental platform regions and indicate normal conditions underlying the basin.

Preliminary report of terrestrial heat flow study in the South American continent; distribution of geothermal gradients

Measurements of terrestrial heat flow have been made in twenty mines in western South America. In addition to these mines, underground temperature data at thirty-five oil fields over the whole South American continent have been examined. Since thermal conductivity values for these sites have not been determined yet, only geothermal gradient values are reported here. The thermal gradient features may be summarized as follows 1.(1) most of the values are normal or subnormal over the whole area of the continent;2.(2) high values are concentrated in the Andes area, and often seem to be associated with geothermal activities3.(3) lower values are …

Terrestrial heat flow in the seas round the Nansei Shoto (Ryukyu Islands)

Thirty-nine heat flow measurements have been made in the seas adjacent to the Nansei Shoto (Ryukyu Islands). Ten are located west and twenty-nine east of the islands. Values range from 0.22 to 5.68 HFU (heat flow units). At stations inside the islands, the mean value is 2.97 ± 1.51 HFU. Outside the islands heat flow is generally subnormal (mean value = 1.17 ± 0.79), although the distribution is rather complicated in detail. The exceptionally high heat flow zone in the Okinawa Trough, on the continental side of the Nansei Shoto Arc, seems to be a southward extension of the high …

Terrestrial heat flow measurements on lake Titicaca, Peru

Between 29 May and 16 June, 1969, 19 succesful observations of terrestrial heat flow were made with Bullard-type probes on Lake Titicaca within the 250-m depth curve. The 19 heat-flow measurements have a mean of 1.32 μcal cm−2 sec−1 (u.f.u.) which is slightly below the continental average Thirteen of these observations were made with a 2.5-in-long probe and for the other six a probe 4.5 m long was used. The differences of temperature gradient found at four depths in the lake sediments can be accounted for by an annual variation of the bottom water of approximately 0.02°C by comparing them …
