Abandoned quarry about 18 km from Rome, near Osteria dell'Osa.

It exploited the rock of the Osa lava flow (297±4 ka; Marra et al., 2003), which lies over the "Villa Senni Eruption Unit" ignimbrites and is an effusive product of a vent of the Pantano Borghese extra-caldera system (Tusculano Artemisio-Monte delle Faete period of activity of the Colli Albani Volcano). This lava is a melilite leucitite, which may differentiate itself locally by assuming the characters of a leucitite nephelinite with melilite and olivine.

The rock frequently holds small cavities containing calcite, often associated with zeolites, fluorapatite, and vonsenite; moreover calcite is present in the form of veins and is also noticeable under a microscope dispersed in the groundmass, often surrounding leucite and nepheline crystals.

The quarry, closed in the middle of the 1970s, has yielded a large number of gismondine crystals (up to 1 cm in size), which probably represent the best crystals for this species from the Colli Albani lava flows.


Anthony et al. (1995, reprinted 2003) reported without references the presence of ashcroftine-(Y). Many specimens of presumed ashcroftine-(Y) submitted for analysis resulted to be amorphous or non-crystalline; they do not contain K and REE (see http://forum.amiminerals.it/viewtopic.php?t=6071). According to Carlini & Signoretti (2018) the lilac, brown or creamy interlaced acicular crystals or felted masses incorrectly attributed in the past by some collectors to ashcroftine-(Y) are referable to more or less altered terms of the ludwigite-vonsenite series.
