Group: Summary

   This catalog of boreholes from across Russia and Mongolia includes those 
   published in papers and monographs as well as other literature of limited 
   circulation. The 122 boreholes were used to derive a characterization of the 
   Russian territory according to eight geocryological regions. Five boreholes 
   are included for Mongolia. Data from these boreholes were used in the 
   generation of the Circum-arctic Map of Permafrost and Ground-Ice Conditions 
   (Brown et al., 1997). Data obtained from various sources as noted within each 
   borehole entry. The time period varies for each borehole, but is primarily 
   from the late 1980s to early 1990s. Observation methods include 'Standard 
   logging', a combined natural gamma logging, electric logging and well caliper 
   logging; 'Geothermal observations' which demonstrate the thickness of layer 
   with the temperature below zero (data of Yakutsk Permafrost Institute, 
   Siberian Branch, Academy of Sciences of the USSR); visual observations on 
   ice-content in the core, and depth of appearance of fresh water table; 
   thermologging of the boreholes (studies of 'PGO Yakutskgeologia'); and 
   electric, well caliper and thermal logging in pioneer and exploratory oil and 
   gas wells ('PGO Lenaneftegasgeologia' studies). The permafrost base is exposed 
   by a number of adjacent boreholes; interval of fluctuations of permafrost 
   depth is shown. The data are presented on the CAPS Version 1.0 CD-ROM, June 
   1998.
