Petrified and carbonified wood specimens sporadically outcropping from a conglomerate bed (mainly consisting of ophiolitic clasts in a sand-clay matrix varying in colour from dark grey to dark green), attributed to the Upper Tortonian (Late Miocene), along a ridge, covered by dense shrub, located at about 70 m a.s.l. on the left side of the Ugione stream (Torrente Ugione), below the Poggio Corbolone ophiolitic body.

Loose specimens, likely coming from this occurence and a similar one located on the right side of the Ugione stream (Collesalvetti municipal territory, see https://www.mindat.org/loc-308080.html), are also found downstream along the Ugione stream bed (that divides the municipal territories of Livorno and Collesalvetti).

Lignite fissures and fractures often contains pyrite, hartite, and gypsum; petrified wood mostly consists of opal, chalcedony, and quartz (crystals less than 2-3 mm in length). A few specimens of wood, internally petrified with some carbonified parts towards the outside, contain garnet-red to dark orange droplets of amber.
