[f. per-1 + mineralization.]
The action or result of fossilization by the deposition of minerals from solution in the interstices of hard tissue. Hence perˈmineralize v. trans., -ˈmineralized ppl. a.
1893C. A. White in Rep. U.S. Nat. Museum 1892 264 There are seven different natural conditions in which fossil remains are recognizable, three of which relate to substance, three to form, and one to both. To those relating to substance I have applied the terms permineralization, histometabasis, and carbonization... The term permineralization applies to that condition of fossil remains of animals which differ least from their original condition as parts of living animals. 1915C. Schuchert Text-bk. Geol. II. xvii. 436 The great majority of fossil specimens preserve more or less of the original hard or mineral substance of the individual plant or animal, and to this may have been added in the organic interstices more or less of other mineral substances during the process of fossilization, forming the permineralized fossils. 1952R. C. Moore et al. Invertebr. Fossils i. 4/1 Shells and bones, which are somewhat porous, may be made more dense by deposition of mineral substances by ground water. Hard parts altered in this way are permineralized; the process of alteration is termed permineralization or petrifaction. 1958C. L. & M. A. Fenton Fossil Bk. i. 5 This process [sc. petrification]..takes place in two related ways. The simpler, termed permineralization, takes place when fat and other organic substances decay while water containing dissolved mineral matter soaks into every cavity and pore of hard—especially limy—structures.
