Abstract

Orographic map of S-E Altai was compiled on the base of DEM with the grid step 20 m and space images with the pixel size 10 m. This map was used for morphometric analysis considering the neotectonic block structure of the territory. The correlation between the block size (M - length, H - width) and Moho's depth (M) was revealed: L = = 2M, H = 0.5M. The distribution of ridges and basins linear dimensions leads to the conclusion that only biggest of them are the subsided blocks, while others are the fracture zones with accumulative mantle.
