英文摘要: Abstract(#br)Several kaolinite occurrences of economic interest have been reported in Europe and are usually interpreted as resulting from weathering during the Paleogene tropical climate. However, a hydrothermal contribution is also recognized in some kaolinite occurrences. Such occurrences are common throughout the Hercynian Armorican Massif, where they are developed mostly on granitoids. The kaolin deposit of the Tertre Rouge pit, South Brittany (France), has been mined for the past 70 years. It is the only deposit developed from carbon-rich (~1% C) Ordovician schists affected by a low-grade metamorphic event during the late Hercynian orogeny. Herein, we report the results of a detailed field and petrological study combining optical microscopy with SEM investigation, XRD analyses, and...
