Langhian
Third Miocene age (15.98–13.82 Ma), originally associated with marly deposits in the Langhe of Piedmont.
Language and route: Italian regional name used in a French scientific proposal. the Langhe hills, Piedmont, northern Italy → historical scientific stage-name Langhian. This is a geographical/eponymic formation, not a Greek life-comparison compound.
Literal gloss: of the Langhe
The name and its history
Lorenzo Pareto · 1865
- What does the word literally mean?
- of the Langhe
- What did the original author mean?
- Pareto proposed a distinct interval corresponding to the Langhe marls, separating them from younger sandy sediments.
- Why was the name needed?
- The northern Italian Tertiary succession was being subdivided by lithology and fossil faunas, but its correspondence to other countries remained uncertain.
- What evidence supported the original concept?
- Regional marl sections and molluscan fossils supplied his ordering; modern planktonic microfossil zones were not yet available.
- How has geology changed the concept?
- The global Langhian occupies the first part of Middle Miocene, with modern correlations driven by fossils, polarity and astronomical calibration rather than the single Langhe contact.
Further historical context

Editorial qualification
Pareto’s 1865 authorship is well established; the exact historical boundary in the original local rocks is not a modern GSSP.
