Abstract
We processed data from geophysical survey archives of the 1950s acquired in intermontane basins in the Baikal rift, including a large collection of vertical electric soundings (VES) from the Barguzin basin, which remained only partly interpreted. The processing and reinterpretation became possible with the advanced computing facilities and software for forward modeling and inversion, and GIS tools. We estimated the electrical parameters and modeled the complex block structure of the uppermost basement and sediments beneath the Barguzin basin.
