Mineraaleina

Mineraaleina is an Estonian term that literally translates to "as minerals." In scientific writing it is used to indicate that a substance, phase, or component is being considered in its mineral form rather than as a chemical compound, mixture, ore, or as a broader coarse aggregate. The phrase often appears in discussions of phase relations, mineral zoning, or the characterization of rock matrices where the distinction between minerals and other constituents is important.

Origin and form: The word combines mineraal (mineral) with the derivational suffix -eina, which in Estonian can convey a state, role, or function. This construction yields a nominal adverbial or adjectival phrase used to specify the mode of description.

Usage: In Estonian geology and mineralogy literature, mineraaleina may appear in phrases such as "mineraaleina esinemine" (occurrence as minerals) or when contrasting properties of minerals with those of bulk rock or environmental materials. The term is relatively specialized and not common in general language; translations into other languages usually render it as "as minerals" or "in mineral form."
