Melilite refers to a mineral of the melilite group. Minerals of the group are solid solutions of several endmembers, the most important of which are gehlenite and åkermanite. A generalized formula for common melilite is (Ca,Na)2(Al,Mg,Fe )[(Al,Si)SiO7]. Discovered in 1793 near Rome, it has a yellowish, greenish-brown color. The name derives from the Greek words meli (μέλι) "honey" and lithos (
Melilites form a solid solution series from pure Gehlenite Ca 2 Al 2 Si 3 O 7] to pure Akermanite [Ca 2 MgSi 2 O 7 ]; although pure members are very rare. Melilite occurs in unusual silica-undersaturated igneous rocks.
In petrology "melilite" usually refers to minerals in the åkermanite-gehlenite series, by far the most abundant members of the group. A large number of synthetic members are
Melilite, any member of a series of sorosilicate minerals that consist of calcium silicates of aluminum and magnesium. Melilites were first described in 1796 and range in color from
As mentioned in Chapter 6, melilite is common in several types of CaAl-rich inclusions in Allende and other meteorites. On Earth melilite occurs in thermally metamorphosed
Abstract. A series of new Eu 2+ -activated melilite-structured phosphor compounds was developed through solid-state reactions. The structural and spectroscopic properties of the phosphors were analyzed; all phosphors
2022年2月3日 The melilites are a group of little-known silicate minerals. In nature, the commonest are rock-forming minerals found in the igneous rocks characterized by a low
