On the basis of study on metallogenic background and deposit characteristics,the relation of volcanic hydrothermal ore-forming process,tectonic reworking,deep source magmatic superimposition and hot underwater reworking with mineralizatoin has been disscussed in this paper.The genesis of the ore depositscan be explained by such a metallogenetic path as rift arc metallogenic background—volcanic hydrothermal mineralization—tectonic reworking—deep source magmatic superimposition—hot hydrothermal reworking.It is thought that the ore deposits are of composite poly-genesis type,and a metallogenic model has been set up.The direction for metallogenic prognosis in the future has been pointed out.
