Meteorites, Comets, and Planets: Treatise on Geochemistry, ...
In fact, the mineralogy of most CAIs in most chondrite types can be defined
mainly in terms of relatively few essential minerals: spinel, melilite, perovskite,
hibonite, calcic pyroxene, metal, anorthite, and olivine. Somewhat rarer but
important ...

Metasomatism and the Chemical Transformation of Rock: The ...
Melilite and anorthite are the major primary CAI minerals susceptible to alteration
; a ̊kermanitic melilite is generally more altered than gehlenitic melilite. Both the
degree of alteration and secondary mineralogies depend on the texture, ...

A Compendium of Geochemistry: From Solar Nebula to the Human ...
The fine-grained spinel-rich inclusions (FSI) consist of irregularly shaped spinel
grains which are often rimmed with Ca pyroxene and dispersed in a porous
matrix of grossular, anorthite, and feldspathoids (i.e., alteration products of
melilite).

Geological Survey Professional Paper
Cleavage surfaces of melilite 0.5 meter across are common. The uncompahgrite
is made up chiefly of the mineral melilite, which has a greasy luster and imperfect
cleavage. In the coarse-grained rocks the melilite encloses the other minerals ...

It forms a matrix in the studied bloom sample together with melilite and less often
with fayalite. and it hosts rich exsolutions of a-iron and wiistite. It contains a small
admixture of MgO up to 0.69 wt.% and a significant FeO content reaching 7.60 ...
