Summary

[edit]
Description

"Rosso Verona Marble" from the Jurassic of Italy.

In the commercial decorative stone trade, “marble” is used to refer to a wide variety of relatively soft rocks (H = 3 to 5) that will take a fine polish. These include true marbles and rocks that aren’t marbles, such as limestones, tectonic breccias, and serpentinites. True limestones are calcitic biogenic and ~chemical sedimentary rocks.

Rosso Verona Marble (a.k.a. “Red Verona Marble”) is a Jurassic-aged, hematitic, stylolitized, nodular limestone from Verona Province in northern Italy. The lighter-colored areas (nodules) have been attributed to soft-sediment deformation (Pivko, 2003). Some samples have fossil ammonite shells (Mollusca, Cephalopoda, Ammonoidea, Ammonitida). This limestone represents part of a condensed succession of sediments deposited on an ancient submarine plateau, the Trento Plateau.

Stratigraphy & Age: Rosso Ammonitico Superiore Member, Rosso Ammonitico Formation, Oxfordian Stage, lower Upper Jurassic.

Locality: commercial quarry near Caprino Veronese or Cerro Veronese or Erbezzo or Sant’Ambrogio di Valpolicella, Verona Province, western Veneto Region (Venetia Region), southern Alps, northern Italy
