It was discovered by and named for the Italian mineralogist Roberto Allori, an avid mineral collector who has also done research on piergorite and willhendersonite.
It was found on the south eastern slope, in the northern part of the caldera, the result of a large volcanic explosion, which in turn created a crater.
The original sample was found within a volcanic bomb that was roughly 4.5 cm in diameter, with the crystals forming within the linings of miarolitic cavities.
The carbon dioxide was determined using the contents on the ascarite sorbent, with selective sorption, held within a gaseous product.
In relation to afghanite's and alloriite's physical properties, they both have a trigonal crystal structure, P31c space group, and then have very similar formulas.
Alloriite is a small crystalline mineral that has only grown up to 1.5 to 2 mm in length and has been related to explosive volcanic building.
