Basing on studying morphologic homogeneous communities # ranges of mountains # as elementary structures of mountain associations, using the photographic materials received at space researches the author analyzes cha#racter of possible interrelation between them. Conditions оf the coordinated behavior of private ranges of mountains and various structural combinations, down to crossing them by each other are established. Interred and dug displays of ranges replacing each other in cuts are revealed.

Character of mutual relation of ranges leads to conclusions about necessity to use a concept of their relative age, representations about polychronic and heterogenic character of orogenesis.
