DISCUSSION OF COMPARISON OF METALLOGENY FOR SEDEX AND SEDIMENTARY-REWORK BASE METAL DEPOSITS

In this paper,we discussed mainly from the tectonic setting,geological enviroment,geological-geochemical feature,ore fluids and metallogenic model of the sedimentary-exhalative-deposit and sedime ntary-rework-deposit,in order to test the similarity and the difference of the two-type deposit,We compared systemically the two-type deposit combining the researching of the massive sulfide deposit in the middle-lower Yantze river reg ion that we are studying.It is beneficial to exploring this two-type deposit.
