Cavernous weathering phenomena (‘tafoni’) are well developed on the granitic and gneissic metasedimentary rock of the Northern Foothills region of Antarctica. Thin sections of weathered bedrock indicate that physical disintegration is associated with the preferential micro‐fracturing of quartz miner...
