What does mineralized mean?
Mineralized describes something that has been converted into, or has become impregnated with, mineral matter. The process often occurs over long periods: in fossils, minerals may gradually replace the original material of bones or shells, preserving a detailed impression of the organism. In medicine and biology, the term can describe tissues hardened by deposits of calcium or other minerals. Mineralized can also refer more generally to a surface, deposit, or sample containing mineral matter. Its precise meaning depends on context, because the word may imply replacement, impregnation, or simply the presence of minerals. It is especially useful in describing the physical processes involved in fossilization, calcification, and the analysis of geological or biological specimens.
