Terrestrial heat flow on Pre-Cambrian shields in the USSR

Abstract

Geothermal gradients, thermal conductivity of rocks and heat flow data are given for the Pechenga area, the Monchegorsk pluton, the Ricolatva area, the Koashva and the Khibini mountains in the Kola peninsula, on the Pre-Cambrian Baltic shield. Heat flow values are low, being respectively 0.85 ± 0.00 HFU; 0.95 ± 0.08; 0.69 ± 0.01; 1.22 ± 0.01; 0.85 ± 0.03 HFU. Comparison of geothermal data with seismological data for the Ukrainian Pre-Cambrian shield is given.
