1852Huxley in Phil. Trans. CXLIII. i. 63 If, however, all Cephalous Mollusks..be only modifications by excess or defect of the parts of a definite archetype, then, I think, it follows as a necessary consequence, that no anamorphism takes place in this group.
3. Geol. Metamorphism below oxidation level resulting in the formation of complex minerals from simpler ones.
1904Van Hise Treat. Metamorphism iv. 169 The lower zone may therefore properly be called the zone of anamorphism, or anamorphic zone. Ibid. 170 The zone of anamorphism may be defined as the zone in which alterations of rocks result in the production of complex compounds from simple ones. 1914Ries & Watson Engin. Geol. iii. 204 Anamorphic zone. The zone of anamorphism corresponds to the zone of flowage, in which there is great pressure in all directions. It is a zone of reconstruction, and is especially characterized by silication involving decarbonation, dehydration, and deoxidation. |
