Basalttit

Basalttit is not a formally recognized mineral or lithology name in major geological references as of 2024. There is no mineral species named basalttit registered with the International Mineralogical Association (IMA). The term occasionally appears in informal discussions or as a possible misspelling or shorthand, and it may reflect confusion with basaltic rocks or with titanite.

In some contexts basalttit may be used as a mistaken reference to basalt, a common mafic volcanic rock. Alternatively, it can be used informally to describe a basaltic rock that contains titanite (CaTiSiO5) as an accessory mineral, or to denote a hypothetical basalt-titanite assemblage. However none of these usages are standard or formally defined. If encountered in literature, the exact meaning should be checked in the source, especially whether the author uses the term as a geological nickname rather than a formal mineralogical designation.

The term appears to be a portmanteau-like construction combining basalt with titanite, but without formal naming rules or defined chemical or mineralogical criteria. In formal writing, it is advisable to refer to established terms—basalt, basanite, or titanite—and to describe mineralogy, texture, and chemistry explicitly.
