Miscibility gap
Abstract
"This problem is an attempt to correlate grade of metamorphism (normally assumed to be temperature dependent) with the shape and dimensions of a solid miscibility gap. Such a correlation might permit mapping of a continuously variable function of metamorphism. The system, calcite and dolomite-ankerite, was chosen for study because of its relative simplicity. Samples of quartz-carbonate granulite were collected from the Waits River formation in southeastern Vermont through a range of metamorphic grades. Refractive index, "molecular" volume, manganese content, and density were determined for the carbonates of four of these samples. These values are plotted on a compositional diagram to show the proportions of the miscibility gap for different grades of metamorphism. No measurable narrowing of the gap is demonstrated. A progressive increase with metamorphic grade in the refractive indices of calcite and ankerite was noted, and an attempt is made to explain it. Other unpredicted relations are mentioned, and a promising single crystal X-ray technique is described. Recommendations are made for further study of this problem"--Abstract, page 1.
