Rocks resistance to blow and selective weathering processes

Abstract

A correlation is analysed between strength characteristics of solid rocks and selective weathering processes, field observation data being used from an alpine area in Central Tier-Shan. Geological and geomorphological survey revealed coincidence of lithornorphic landform boundaries (i, e. cirque walls bases), petrographic contacts and ore zones. The cause of the coincidence is concluded to be selective character of the denudation and ore formation, both processes making use of weak zones in rocks.
