We review the sea-bottom heat-flow determinations and present a new heat-flow observation on the Mauritius island, which is part of the long-lived Reunion hotspot track. The marine heat flow is on average 66 ± 11 mW m−2 and is consistent with the on-land value of 61 ± 18 mW m−2 found in Mauritius. Since these values do not significantly deviate...

We investigated the influence of groundwater flow on the thermal tests performed in borehole heat exchangers to infer the underground thermal properties. Temperature–time signals were simulated with a moving line source (MLS) model under different hypotheses of Darcy velocity. Periodic and random noise was included in the synthetic data...

An apparatus (Transient Divided Bar - TDB) was implemented to determine the thermal conductivity of rocks. TDB consists of a stack of elements, which comprise a rock specimen placed between two copper blocks of cylindrical shape with known thermal capacity, initially kept at room temperature. The lower block is then cooled, and temperature...

The connection between the thermal field and the mechanical properties in the northern sector of the Tyrrhenian–Apennines system is analysed. The thermal setting is the result of three main extensional events, which have taken place within relatively small space and time intervals. The oldest tectono-thermal event took place in eastern Corsica...

We present techniques to infer thermohydraulic parameters from the analysis of underground temperature data from boreholes. Two different cases are analyzed: thermal data from artesian wells and from boreholes drilled in unconfined aquifers. The former allow the assessment of the formation temperature gradient and the flow volume; the latter...
