 Solidus - Wikipedia, the free encyclopedia
In chemistry, materials science, and physics, the solidus is a line on a phase diagram below which a given substance is stable in the solid phase.
The solidus and liquidus do not necessarily align or overlap; if a gap exists between the solidus and liquidus, then within that gap, the substance is not stable as either a solid or a liquid.
The solidus may be a straight line, or it may be curved, depending upon the substance.

 Liquidus - Wikipedia, the free encyclopedia
The liquidus and solidus do not necessarily align or overlap; if a gap exists between the liquidus and solidus, then within that gap, the substance is not stable as either a liquid or a solid.
The liquidus may be contrasted to the solidus.
In chemistry, materials science, and physics, the liquidus is a line on a phase diagram above which a given substance is stable in the liquid phase.

Analyses of fluid inclusions and microstructures within the Papoose Flat pluton were used to investigate the chemistry and temperatures of fluids circulating with the pluton during cooling.
Coexisting andalusite and cordierite in the contact aureole, and the intersection of the Mus + Qtz dehydration reaction with the granite solidus, indicate trapping pressures between 3.8 and 4.2 kb.
Ninety-eight percent of the calculated fluid inclusion trapping temperatures at 3.8 - 4.2 kb are below the granite solidus of 650°C. Seventy-six percent of the trapping temperature data fall within the more restricted range of 350-500°C; i.e.

 Phase diagram - Wikipedia, the free encyclopedia
For a phase diagram with temperature on the vertical axis, a solidus is a line below which the substance is stable in the solid state.
In physical chemistry and materials science, a phase diagram is a type of graph used to show the equilibrium conditions between the thermodynamically-distinct phases.
However, it is impossible for the solid-liquid phase boundary to end in a critical point in the same way as the liquid-gas boundary, because the solid and liquid phases have different symmetry.

A triple point is, in a pressure-temperature phase diagram, the unique intersection of the lines of equilibrium between three states of matter, usually solid, liquid, and gas.

O and CO However, both of these volatile components have the potential to lower significantly the solidus temperatures of mantle peridotite and alter the chemistry of primary melts.
Picritic glasses found in turbidite sands near the submarine part of Kilauea's East Rift Zone contain up to 15 wt.% MgO and are the most magnesian Hawaiian volcanic glasses reported to date ( Clague et al.
They have olivine phenocrysts as magnesian as Fo, and when their compositions are plotted together on normative diagrams, they form a distinct olivine fractionation trend.
