A melilite-olivine nephelinite lava flow occurring in Hamada, SW Japan, is the most silica-undersaturated lava known to have erupted in Japan (SiO 2 content ∼37 wt %), and may be a least fractionated melt from mantle depths. Heterogeneity of elements such as Si, Al, Ca, and alkaline elements is one of the characteristic features of the Hamada nephelinites and is attributed to.

Melilites are tetragonal sorosilicates and form short prismatic crystals with poor basal cleavage. The Mohs hardness is 5-6, and the density increases progressively from 2.94 for akermanite to 3.05 for gehlenite.

The Al-rich relict melilite grains and their overgrowths exhibit the same O-isotopic compositions, while the O-isotopic compositions are varied spatially among melilites. We found that the O-isotopic compositions steeply change across several melilite crystals within few tens of micrometers, indicating the O-isotopic compositions of the melt could not have been homogenized during the partial. 6-14 micron Spitzer spectra obtained at 6 epochs between April 2005 and October 2008 are used to determine temporal changes in dust features associated with Sakurai's Object (V4334 Sgr), a low mass post-AGB star that has been forming dust in an eruptive event since 1996.

More meanings of melilite - میلیلائٹ, it's definitions, example sentences, related words, idioms and quotations In many Type B Allende inclusions, melilite is reversely-zoned over restricted portions of each crystal. Textural relationships and the results of dynamic crystallization experiments suggest that the reverselyzoned intervals in these Type melilites result from the co-precipitation of melilite with clinopyroxene from a melt, prior to the onset of anorthite precipitation

melilite noun — ( mineral ) any mineral consisting of a solid solution of gehlenite ( Ca 2 Al 2 SiO 7) and akermanite ( Ca 2 MgSi 2 O 7) Übersetzungen melilite Übersetzun Melilite. Melilite is a rarely occurring mineral from the mineral class of silicate and germanate . It crystallizes in the tetragonal crystal system having a chemical composition (Ca, Na) 2 (Mg, Al) [ Si2O7 ], and usually develops only small crystals in the millimeter range with tabular or short to langsäuligem habit, but also granular to bulky mineral aggregates Melilite and potassic richterite are not phases that can crystallize together in sodic-alkaline magmas. The unusual geochemical and isotopic composition of the Rajpuri intrusion, indicating magmas derived from old, enriched lithospheric mantle, and the presence of melilite, are strong indication that this is one of the most peculiar alkaline intrusions related to the Deccan Traps.
