Melt inclusion

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 hydrothermal systems. Melt inclusions tend to be microscopic in size (10-80 µm) and can be analyzed for volatile contents that are used to interpret trapping pressures of the melt at depth.
