What does mineralised mean?
Mineralised means that a material has been converted into a mineral substance or has become impregnated with minerals. The process often involves minerals gradually replacing organic material, as may happen to bones, shells, fossils, and other remains, preserving their form while changing their composition. Mineralisation can also describe the accumulation of mineral salts or deposits in soil, rock, or water. In these contexts, the word conveys both a scientific transformation and the gradual hardening or petrification associated with mineral-rich environments. It is chiefly a British form; the equivalent American spelling is mineralized. The term is especially useful in geology, palaeontology, chemistry, and environmental science, where it distinguishes mineral formation or mineral impregnation from ordinary decay or physical weathering.
To convert a substance into a mineral or mineral-like material, or to impregnate it with mineral deposits.
"Groundwater mineralised the surrounding rock over many centuries."
Chiefly used in technical and scientific contexts.
Converted into or containing mineral material or deposits.
"Researchers discovered mineralised bones inside the cave."
This is the participial form of the verb and is especially common in descriptions of fossils, remains, rocks, soils, and water.
A fossil may preserve the shape of an organism long after minerals have replaced nearly all of its original material.

Etymology of mineralised
The word is formed from mineral together with the suffix -ise, meaning to make or cause to become. Mineral ultimately derives from Latin mineralis, meaning “of ore or minerals,” from minera, meaning “ore.” The same Latin foundation also underlies related English words such as mineralogy and mineralogist.
