Abstract
Summary
Borders’ establishment of talik is the major task at all stages of studying of any engineering object. The solution of the matter assumes the stage-by-stage solution of a task by the principle “from the general to the particular” using a complex of methods such as landscape cryoindication, land geophysical surveys and thermometric researches.
On the results of multispectral space pictures decryption Landsat it is established that the central and peripheral parts of the natural occurrence are characterized with a surface existence of thawed rocks, northwest and southeast flanks of the field are characterized with frozen rocks.
Based on interpretation results of geophysical data the talik zones’ situation in the plan and a section is specified. At the third stage measurements of temperatures in wells are executed. On the results of which it is established that frozen rocks are characterized by continuous extention up to the depths of 80–240 m and have a double-layer structure. The sole of a sublayer has the symmetric character relative to central part of the field, rising to field’s flanks.
