Cava Boschetto di Chiampo [upper Chiampo Marble] - Coleoidea (Eocene of Italy)

Also known as Cengio dell’Orbo

Where: Italy (45.5° N, 11.3° E: paleocoordinates 39.2° N, 9.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Chiampo Marble Formation, Lutetian (47.8 - 41.3 Ma)

• STRATIGRAPHIC RELATIONS: From the upper member of the Chiampo Marble, which overlies Palceoen pyroclasic layers, and is overlain by volcanics of Middle and Late Lutetian age. AGE: early Lutetian. Age is presumably justified on the basis stratigraphic positioning between dated Ypresian and Late Lutetian volcanics. STRATIGRAPHIC POSITION: From upper reworked hyalocalstic in middle of sectionof about 25 m thickness.

• bed-level stratigraphic resolution

Environment/lithology: poorly lithified, shelly/skeletal, sandy, conglomeratic volcaniclastic sediments

• ENVIRONMENT: Unknown environment, but carbonate, and shallow marine on the basis of macrofossil composition.
• SPECIFIC LITHOLOGY: Reworked hyaloclastite with arenaceous grain size, made of angula siliciczed baslatic fragments, calcareous fragments, and calcitic cement. LITHIFICATION: Poorly lithified, on the basis of figured specimens and systematic descriptions.

Size class: macrofossils

Preservation: replaced with calcite

Collection methods: surface (in situ),

• COLLECTOR: Unknown. REPOSITORY: Montecchio Maggiore (MCZ) (Vicancenza), Italy.
