Abstract
Many geomorphological studies have ignored the role of thermal stress fatigue. Engineers have long maintained that thermal stress is an effective process. Physicists and the ceramics industry have provided a theoretical foundation to explain the nature and mode of operation of thermal breakdown. Recent geomorphological studies have shown the importance of thermal stress in cold regions by means of high-frequency rock temperature data which can identify rates of temperature change in excess of 2 C min-1. The occurrence of weathered material in cold but dry regions can be explained by thermal stress/shock. Differential radiation receipts on slopes of varying orientation and gradient can exert a very strong effect.
