Identification and mapping of rock weathering surface forms and features

Recent approaches to the identification, measurement and mapping of rock weathering forms in the field at micro and meso scales (millimeters to meters) are discussed from the literature of both geomorphology and stone conservation. The means and techniques of observation have undergone significant development in recent years, with the increasing application of mechanical, digital and imaging techniques. The observation of weathering forms may be undertaken at the scale of the individual site, or at a broader geomorphological scale, at which a sampling scheme may be designed to form a comparative survey or purposive experiment. The value of form observations lies in the contribution they are able to offer to the understanding of weathering processes and the development of models and theories of landform evolution
