formaiunilor

Formaiunilor is a Romanian term found primarily as a genitive/dative plural form related to the concept of formations. In standard Romanian, the corresponding plural nominative would be formațiunile and the genitive plural formațiunilor. Formaiunilor is thus often treated as a nonstandard or historical variant that appears in some older texts or regional writings. In contemporary usage, it is generally advised to prefer formațiunilor to avoid orthographic ambiguity.

In geological and geographical contexts, formațiuni (and by extension, formaiunilor in older texts) refer to stratigraphic units defined by characteristic rock types, fossils, and a distinct time interval. Such units are used to organize and map the Earth’s lithology, summarize depositional history, and correlate rocks across regions. When formaiunilor appears, it is typically within phrases indicating possession or relation, such as “perimetrul formaiunilor” or “componența formaiunilor,” though modern authors would more usually write formațiunilor.

In archaeology and cultural geography, the concept of formations is applied to stratified deposits and occupation layers that record sequential human activity. Here, formaiunilor has historically appeared in reports and descriptions to denote groups of layers or phases, but current Romanian terminology favors formațiunilor or, in some subfields, terms like straturi stratificate or unilaterally defined units, depending on methodological preferences.

Orthography and standardization: most Romanian references today standardize the word as formațiunilor. When encountered as formaiunilor, readers should consider it a variant spelling, a typographical artifact, or an older usage, and interpret it within its contextual domain and time period.
