The Study Of Carlin-type Gold Deposit Styles And Prospecting Directions To Explore In Zhen'an

The article researches the Carlin-type gold deposit in zhen'an country. The carlin type gold deposit mainly includes Ertaizi gold deposit and Donggou gold deposit, and the latter deposit lies in Jinlongshan metallogenic belt.On the basis of completely summing the previous research results and field geological investigation, collecting large geological massages and fossil minerals and rocks, the deposits are studying using some theories and methods, which including modern petrology, mineralogy, ore mineralogy, geochemistry, remote-sensing geology and metallogenic prognosis theory. With the study of the regional metallogenic background and evolution history of geological tectonic in this area, and the geological characters and metallogenic characters of Ertaizi deposit and Donggou deposit, the main ore control factors and metallogenic conditions of the gold deposits are analyzed. And the discussion of genesis are made using the geochemistry characters, which including texture, structures, stable isotope, trace elements and rare earth elements of the minerals, and inclusion temperature. And the ore genesis is related to the favorable strata, tectonic and metallogenic hydrothermal. At last, through the metallogenic prediction research, the exploration targets and key region are pointed out.
