We analyze 48 geothermal estimates of Pleistocene/Holocene warming amplitudes from various locations in Greenland, Europe, Arctic regions of Western Siberia, and Yakutia. The spatial distribution of these estimates exhibits two remarkable features. (

This paper reports the results of a series of laboratory experiments on forming synthetic methane and tetrahydrofuran (THF) hydrates in sand samples and measuring their acoustic properties, i.e. P- and S-wave velocities. Experimental data were used f

Thermal recovery in boreholes cooled by circulation of drilling mud has been modeled for estimating formation temperature and thermal conductivity. Coupled with a finite‐element simulation of heat conduction, inverse modeling for the desired parame

Multi-channel seismic studies (MCS), performed during a Russian expedition in 1989 and a joint Russian-American expedition in 1992, have for the first time revealed a “bottom simulating reflector” (BSR) in Lake Baikal. These data have shown that

[1] We analyze borehole temperature logs from 101 sites in Russia and nearby areas to reconstruct the ground surface temperature history (GSTH) over the past five centuries. The data are drawn principally from three regions: the Urals, southwest Sibe

Information on the heat flow of Siberia is summarized and methods of geothermal measurements are briefly described. Based on the heat flow data (more than 1100 determinations) a map of the heat flow (in isolines) has been compiled. Proposed are the d

The results of geothermal research carried out in South Siberia (West-Siberian and Siberian Platforms, Altai-Sayan folded area and the Baikalian arched uplift zone) were employed to calculate the Earth's crustal temperatures. It is shown that tempera
