The Mineral glaucophane

Glaucophane is named from a combination of the Greek words Glaukos, meaning "blue", and Phainelein, meaning "appearance", alluding to its bluish color. Glaucophane forms a series with the less-common Ferro-glaucophane, where Glaucophane is the magnesium-rich end member and Ferro-glaucophane is the iron-rich end member.

Experimental studies on glaucophane: An analysis of

A review of the evolution of experimental work on synthetic, end-member, iron-free glaucophane, Na 2 Mg 3 Al 2 SigO 22 (OH) 2, leads to the conclusion that it is unlikely that an amphibole of this composition has yet been synthesized.Although some amphiboles obtained in these studies at synthesis pressures of 20–30 kbar P H 2 O may approach end-member …

Molar volume and thermal expansion of glaucophane

The molar volume of glaucophane [Na2Mg3Al2Si8O22(OH)2] has been determined in this study by correcting synthetic glaucophane-rich amphiboles made in the system Na2O–MgO–Al2O3–SiO2–H2O for very small deviations from ideal glaucophane composition using recent volume data on key amphibole components. The derived unit-cell volume for end …

Glaucophane

Glaucophane and lawsonite, both of which have a bluish color, are common minerals in this setting. In subduction zones, crustal fragments can be carried to great depths (>50 km), yet remaining at rather low temperatures, usually <400°C (see Figure 2.9). A major unsolved question is how these rocks return to the surface.
