The paper considers some possibilities of the mountains' morphostructural analysis on the basis of space data. Regional examples of space photoes interpretation are given, folds, blocks and volcanic structures were identified within Pacific and Mediterranean belts. The examples testify to the scientific and technological efficiency of the remote sensing application to geotectural and morphostructural studies of lineaments, linear and isometric structures on various scales. Space morphostructural analysis indicates the lineaments cross each other within the orogenic belts which is the evidence for more complicated pattern of deformations there as compared with island arcs.
