A PRELIMINARY STUDY ON THE MECHANISM AND PHYSICO- CHEMICAL CONDITIONS OF FORMATION OF GONGCHANGLING RICH IRON DEPOSIT

Zhao Bin and Li Tongjin  
Field observation and results of experimental studies show that Gongchangling rich iron deposit is characterized by multigenesis as a result of repetition of different geological processes. It probably resulted from the infiltration of silica under the in-fluence of aqueous solutions derived from migmatite-granite. Because the formation of rich iron deposit was accompanied by the formation of skarn minerals and the trans-formation of sediment-metamorphic poor iron deposits, characteristics of both skarn deposits and strata-bound ore deposits can therefore be recognized. Experimental data indicate that physico-chemical parameters of formation of rich iron deposit are P = 2kbar, T = 500-600℃, pH = 8-10. and f_(O2) = 10-25 bar.
