Abstract: Physical and mechanical properties were carried out on core samples of metabasalts, amphibolites and gneisses from various depths of the Kola Superdeep borehole (KSDB-3) measured at uniaxial and triaxial loading conditions. The same tests were performed on the samples of their surface analogues. The comparative investigations between values obtained on the core samples from the various depths in the borehole cross section and their surface analogues gave valuable information about changes of these properties as a function of depth. An idea of the stress condition assessment based on laboratory tests was initiated. The results of tests are in some cases affected by the small amount of rock material that we had at our disposal. |
