An active (personal visit: Mavris, 2008) quarry exploited by Cementi Rossi SpA for high siliceous cement ("pozzolana"). The quarry is set within the Contignaco Formation, which consists of the early Miocene hemipelagic siliceous marls and silty marls, with few tripoli (siliceous limestone) beds and volcaniclastic layers of rhyolitic composition.

The marls interacted with local intense gaseous activity (mostly methane). The precipitating amorphous silica, combined with methane, crystallized as melanophlogite. Melanophlogite is found in veins and pockets, only in the more siliceous and compact levels of the Contignaco Formation, i.e., those with apparently lower porosity. It is always found in association with opal.

Melanophlogite appears here mostly as cubes, from 0.1 to 1 mm in size, on thin opal CT layers and occurs in veins that are never completely filled; in filled veins, only opal is found. A thin crust of opal (<1 mm) is always found between melanophlogite and the host rock. Pure melanophlogite is quite rare: the geological settings in the place changed and so is very frequent to find pseudomorphs of quartz or CT-opal after melanophlogite. Opal is also found at the core of some melanophlogite crystals.
Melanophlogite does not show birefringence even in thick sections; no evidence of twinning was found by optical observation.
