... of Johannes (1968) for the reaction clinochrysotile + brucite = 2 forsterite + 3 steam were used to calculate the free energy of formation of clinochrysotile. The value obtained (−4,030.84 ± 4.0 kJ mol −1 ) agrees well with published values. As an independent check, the free energy of talc was calculated...

When chrysotile and PS coexist or are indistinguishable, we will call them fibrous serpentine (FS), regardless of their ratios. By researching the occurrence, distribution, microtexture, crystal...

... fiber photographs, and chemical tests and have been determined to consist of clinochrysotile, antigorite, and a one-layered orthogonal mineral similar to lizardite and chamosite in x -ray patterns. This mineral is considered to be chamosite in this paper. Partial chemical analyses show that all three...

...ROBERT G COLEMAN Abstract Mineralogically, serpentinites consist predominantly of lizardite, clinochrysotile, and antigorite. Recent work has shown that these minerals are not polymorphs. Chrysotile is the only mineral recognized as a synthetic product in experimental studies of the system MgO-SiO...

Parachrysotile is considered to be an additional polymorph, rather than a polytype ( Veblen and Wylie 1993 ). There is considerable uncertainty as to the relative thermodynamic properties, and hence stabilities...
