WebAug 1, 2012 · A small number of data come from analysis of natural glasses. About 4600 melt inclusions are from granites, and about 2100 melt inclusions are from pegmatites. Another 4159 values are from melt inclusions and glasses of rocks with more than 66% (g/g) SiO 2 are added belonging to a recent compilation. The total of 10,859 melt … Melt inclusions can be found in both volcanic and plutonic rocks. In addition, melt inclusions can contain immiscible (non-miscible) melt phases and their study is an exceptional way to find direct evidence for presence of two or more melts at entrapment. Analysis See more A melt inclusion is a small parcel or "blobs" of melt(s) that is entrapped by crystals growing in magma and eventually forming igneous rocks. In many respects it is analogous to a fluid inclusion within magmatic … See more Although they are small, melt inclusions can provide an abundance of useful information. Using microscopic observations and a range of chemical microanalysis techniques geochemists and igneous petrologists can obtain a range of unique information … See more Henry Clifton Sorby, in 1858, was the first to document microscopic melt inclusions in crystals. The study of melt inclusions has been driven more recently by the development of … See more • Frezzotti, Maria-Luce (January 2001). "Silicate-melt inclusions in magmatic rocks: applications to petrology". Lithos. 55 (1–4): 273–299. See more Melt inclusions are generally small - most are less than 80 micrometres across (a micrometre is one thousandth of a millimeter, or about 0.00004 inches). They may contain a number of different constituents, including glass (which represents melt … See more Volatile Concentrations Melt inclusions can be used to determine the composition, compositional evolution and volatile components of magmas that existed in the history of magma systems. This is because melt inclusions act as a tiny pressure … See more • Inclusion (mineral) • Fluid Inclusion See more
