Methods for measuring rock surface weathering and erosion: A critical review
2014
Studies of rates, processes and modes of rock surface, and near-surface, deterioration, and also hardening, are central to
rock weathering and building stone research, conservation and management. There is a need to measure and monitor
weathering at the rock–atmosphere interface to facilitate understanding of climatic, environmental and lithological controls
on the evolution and development of surface weathering features. This paper reviews long-established and recently
developed field and laboratory methods used by geomorphologists to monitor and measure the impact of
weathering and erosion on physical and mechanical properties of exposed rock surfaces and their immediate subsurface.
Key advances are highlighted, their application to multi-scalar understanding and modelling of rock surface
weathering in different contexts is discussed and potential future advances to provide new insights into rock
weathering, durability and materials conservation are identified. In highlighting key advantages and disadvantages of
a wide range of methods to the broader earth science community, the paper aims to contribute to further innovative
thinking across disciplines to develop new methods for measuring and monitoring rock weathering.
