neomorphism

   A microscopic texture. A complex of processes whereby a mosaic of finely crystalline carbonate is replaced by a coarser (sparry) mosaic without the development of visible porosity. Dominant reactions are the wet transformation of aragonite to calcite and recrystallization. The process is ‘porphyroid’ where some of the neomorphic crystals are conspicuously larger than those which surround them [20].
   Synonyms: (French.) néomorphisme; (German.) Neomorphismus ?; (Greek.) neomorphismós; (Spanish.) neomorfismo; (Turkish.) neomorfizm.
