Heat flow into underground openings: Significant factors.
This project investigates the heat flow from the rock into ventilating airways by studying various parameters. Two approaches have been used: laboratory measurement of thermal properties to study their variation, and analytic and numerical models to study the effect of these variations on the heat …

Heat flow and tectonics of the Ligurian Sea basin and margins
Heat flow, tectonic subsidence and crustal thickness distributions in the Ligurian Basin are best explained by asymmetric lithospheric thinning mechanisms. Over 150 heat flow measurements are made on several transects between Nice, France and Calvi, Corsica on continental slope and rise settings. …

Surface heat flow and lithospheric thermal structure of the northwestern Arabian Plate
The surface heat flow (qs) is paramount for modeling the thermal structure of the lithosphere. Changes in the qs over a distinct lithospheric unit are normally directly reflecting changes in the crustal composition and therewith the radiogenic heat budget (e.g., Rudnick et al., 1998; Förster and …

Correcting heat flow data in the United States to account for climate change
<p> Heat flow measurements may require correction for both recent warming and post-glacial warming signals. Warming during the last century can be detected in borehole temperature profiles. Both climate warming signals during the past century and post-glacial warming signals during the past 10 …
