Internal weathering in quartz grains

Description :
This paper presents the first systematic analysis of quartz internal weathering. This study demonstrates that internal weathering is ubiquitous in quartz. Internal weathering is measured in terms of porosity, which represents mass loss from the quartz grain, hence silica lost through dissolution. Finally, some of the broader geomorphic implications of internal weathering are discussed, with a focus on the production of detrital quartz, the dissolution of silica, the evolution of weathering landforms, and the creation of secondary porosity in sediments.
