An abandoned quarry located between Podere Pantano and Podere Pian di Celle, to the south of San Venanzo. Olivine-leucite pegmatoid melilitolite veinlet (dyke) swarm in lava flow of the Pian di Celle volcano.

The Pian di Celle tuff-ring and lava flow (Pian di Celle volcano) belong to the San Venanzo volcanic complex, which also comprises the large San Venanzo maar and the small isolated diatreme of Celli. Peralkaline kamafugite and phonolitic foidite make up 80 % of the volcano volume (Stoppa & Cundari, 1998; Zanon, 2005), in which the lava flow is a leucite–kalsilite–olivine melilitite (also known under the local name of venanzite). The remaining 20 % of the volcano volume includes carbonatite tuffs that form indurate beds of mixed carbonatite–melilitite agglomerates and ash-fall carbonatite layers. The pegmatoid kamafugitic melilitolites represent the final event in the development of the Pian di Celle volcano (Stoppa, 1995). They form a dykelet swarm in the NE flow front of the Le Selvarelle venanzite lava of the Pian di Celle volcano at Vispi Quarry.

Vesicular pegmatoid kamafugitic melilitolites contain tabular melilite (up to 5 cm), olivine (Fo>60), leucite, fluorophlogopite, and Ti-rich magnetite as essential minerals that resemble the fine-grained groundmass of the hosting venanzites. Interstices between essential minerals are filled with aggregates of Ti-rich magnetite, fluorophlogopite, fluorapatite, nepheline, kalsilite, diopside, Zr- and Ti-disilicates (members of cuspidine–hiortdahlite and götzenite), solid solutions of ferroan monticellite and magnesian kirschsteinite, umbrianite, fluorite–calcite globules and green to brown glass (Sharygin et al., 1996a and b; Stoppa et al., 1997; Sharygin, 1999, 2001, 2012; Bellezza et al., 2004; Sharygin et al., 2013). In addition, micrometre-sized rare minerals (usually < 20 μm) occur directly in the glass or as daughter phases of silicate-melt inclusions hosted by early minerals. They are westerveldite, sulphides (pyrrhotite, bartonite-chlorobartonite, galena), Na- and REE-rich perovskite and fluorapatite, khibinskite, ilmenite, Na-rich pyroxene and amphibole (Zr-bearing aegirine, arfvedsonite), K- and Ca-containing bario-olgite and a mineral of the bafertisite group. The Cr-rich mineral of the magnesioferrite–magnetite series occurs as inclusions in olivine. The majority of minerals occur as well-shaped crystals in numerous vugs (up to 3 cm in size). Some cavities also contain calcite, vanadinite, rhodesite, willhendersonite, chabazite-Ca, phillipsite-Ca, thomsonite-Ca and members of fluorapophyllite-(K) - hydroxyapophyllite-(K) series. Some parts of the melilitolite dykelet may contain abundant large ocelli of calcite (up to 20 vol.% of the rock).
The alteration processes are not very significant and correspond to partial to complete replacement of bartonite by a Cu-Fe-hydrated sulphide, the appearance of a Ba-rich hydrated rim around umbrianite, colour changing of the groundmass glass from green to brown with the appearance of Ca-Fe-H2O- and Mg-H2O-silicates in brown glass (Stoppa et al., 1997; Sharygin et al., 2013).

Pian di Celle Volcano is one of the classic localities for kalsilite (Mittempergher, 1965 and other authors). However, it is worthy of note that many specimens of acicular fluorapatite are wrongly attributed to kalsilite by mineral collectors. Kalsilite crystals, which have invariably a pseudohexagonal prismatic habit, are often cloudy and yellowish in colour. On the contrary, fluorapatite crystals, which exhibit an acicular or slender prismatic habit, are mostly transparent and colourless and often coated with calcite or other microcrystalline phases (Preite & Gatta, 2011).

The olivines of Pian di Celle volcano are magnesium dominant (forsterite). For the olivines contained in vesicular pegmatoid melilitolites, the molar percentage of forsterite is higher than 60%. In venanzite, the olivine phenocrysts (usually 0.5-0.7 mm in size), which occur in a crystalline matrix consisting of large elongated melilite crystals (up to 0.4–0.5 mm long) and fine-grained aggregate of leucite, kalsilite, larnite, calcite, and titanian magnetite, are represented by a core of extreme Mg olivine (Fo up to 99.49 mol%) surrounded by a rim of high-Mg olivine (Fo >88 mol%), which, in turn, is often overgrown by a thin monticellite rim (Plechov et al., 2017).

The mica mineral, classified as phlogopite or fluorian phlogopite by the authors before the institution of the species fluorophlogopite (2006), has been reclassified as fluorophlogopite. According to the analytical data (Cundari & Ferguson, 1991; Cruciani & Zanazzi, 1994), the fluorine content is 1.40 pfu.

The following phases are with specific properties:
Bartonite-chlorbartonite series
Cuspidine var. Na-Zr-rich cuspidine
Kirschsteinite var. Mg-rich kirschsteinite
Magnesioferrite var. Cr-rich magnesioferrite
Monticellite var. Fe-rich monticellite

Vispi Quarry is the type locality for willhendersonite, a triclinic zeolite related to chabazite and erionite, always occurring as twinned aggregates (usually up to 1.0 mm in diametre) formed of crystals in three different orientations, each with faces approximately perpendicular to those of the others, and arranged in most specimens to have a "trellis-like" appearance (Peacor et al, 1984). Willhendersonite is colourless or white with vitreous lustre; the cleavages are perfect, parallel to {100}, {010} and {001}, and easily produced. These three cleavages are equivalent to the rhombohedral cleavage of chabazite. Willhendersonite is usually associated with other zeolites (phillipsite-Ca, thomsonite-Ca, and chabazite-Ca), melilite, members of fluorapophyllite-(K) - hydroxyapophyllite-(K) series, calcite, fluorophlogopite, fluorapatite, and kalsilite. The most dominant of these associated minerals is phillipsite-Ca, which occurs as radiating sprays of colourless crystals formed contemporaneously with willhendersonite. The two minerals are often intergrown but without any obvious mutual orientation.

Vispi Quarry is the type locality for umbrianite, one of the late-magmatic minerals in melilitolites, usually localized in glass in association with leucite, kalsilite, and fluorophlogopite. Sometimes it occurs as a daughter phase in silicate-melt inclusions in leucite, kalsilite, and melilite. Umbrianite was first described in melilitolite from the same locality as a "delhayelite-like mineral" on the basis mainly of its chemical composition (Stoppa et al., 1997; Sharygin, 2002). Later, more detailed studies showed that this mineral is a representative of the new, triple-layer phyllosilicate structure type, similar to günterblassite and hillesheimite (Sharygin et al., 2013). Umbrianite forms rectangular, lamellar or lath-shaped crystals (up to 25x30x200 μm), typically flattened on {010}, and sheaf-like aggregates (up to 200–500 μm across). It is colourless and transparent in thin sections, the streak is white. The mineral is non-fluorescent in the UV and cathode rays. It has a vitreous luster. Cleavage is perfect on (010) and distinct on (100) and (001). Fracture is stepped to uneven across cleavage. Umbrianite is unstable during postmagmatic alterations. The fresh mineral is common in green glass, whereas crystals in brown glass are partly or completely replaced by Ba-rich hydrated phases.
