| Abstract: | The forming processes of such kind of deposits can be primarily divided into two metallogenic and alter-ation epoches.The first is the sediment of volcanic eruption,and the second is the superimpeed refnrm by subvolcanic gasand liquid. Through study of the evolution of caldera,the author expounds the control of annular volcanic structures tothe formation of ore deposit. |
