Senefelderin

Senefolderin is a term that appears in limited, informal mineralogical contexts as the name of a purported mineral said to be named in honor of Alois Senefelder, the inventor of lithography. There is no widely accepted description, type specimen, or chemical formula for a mineral by this name in major mineral databases or peer‑reviewed literature, and the name is not listed as a valid mineral in standard references.

Etymology and naming: If Senefelderin corresponds to a real mineral, the name would honor Alois Senefelder (1771–1834) for his contributions to printing technology. The form of the name suggests a linguistic convention used to form mineral names, but there is no authoritative documentation detailing the intended composition, locality, or provenance.

Status and interpretation: In the absence of a formal description or published data, Senefelderin should be treated as unverified or hypothetical. Any future recognition would require complete mineralogical characterization and submission to the International Mineralogical Association for approval, including designation of a type specimen and information on structure, chemistry, and occurrence.
