摘要
Alteration of hedenbergite,diopsite(both natural and synthetie),and andradite bas been experimentally studied at 300-800℃ and 200-2,000 atm.The alteration in various degree has been noted for all these minerals in solutions over a wide range of pH values.It has been shown that,hedenbergite is the most unstable,while andradite the most stable,A preliminary disenssion is given in the light of experimental resalts and pertinent geological environments.
Alteration of hedenbergite, diopsite (both natural and synthetic), and andraditehas been experimentally studied at 300--800℃ and 200--2,000 atm. The alterationin various degree has been noted for all these minerals in solutions over a wide rangeof pH values. It has been shown that hedenbergite is the most unstable, while and-radite the most stable. A preliminary discussion is given in the light of experimentalresults and pertinent geological environments.
