Abstract：Raman spectroscopy of dissolution and transformation of chloropinnoite in 4.5%(w.t.%) boric acid aqueous solution at 30 ℃ has been recorded. The Raman spectra of kinetics process have been obtained. The phase transformation product is kurnakovite(2MgO·3B2O3·15H2O). The main polyborate anions and their interaction in aqueous solution have been proposed according to the Raman spectrum. Some assignments were tentatively given and the relations between the existing forms of polyborate anions and the crystallizing solid phases have been gained. Ａ mechanisms of dissolution and crystallization reactions and the formation condition of kurnakovite in Qinghai-Tibet plateau were proposed and discussed.
