A type of mineral or rock formation characterized by a specific crystal structure or composition formed under particular geological conditions.
From Greek 'kata' (down, breakdown) + possibly 'spilites' (a type of altered basaltic rock). The term appears in specialized geological and mineralogical literature.
Rocks tell stories through their crystals—cataspilite formations can reveal ancient processes like ocean-floor volcanism or deep-Earth metamorphism that happened millions of years ago.
