Mineralization and Alteration of a Modern Seafloor Massive Sulfide Deposit Hosted in Mafic Volcaniclastic Rocks

کانی‌شناسی و زمین‌شیمی کانسار مس بزجانی، غرب فریمان، شمال شرقی ایران

The Bozjani copper deposit is located about 30 km west of Fariman city, Khorasan Razavi Province. Host rocks to mineralization are mostly pridotites and basalts of Fariman ophiolitic sequence. Ore body consists of two parts: lower and upper. Lower part has formed a stringer of primary sulfides as stockwork, veinlets, and disseminated. Uppermost part has lenticular shaped dominated by ribbon-lik...

Geochemical Characterization of Sulfide Mineralization in Eastern Wisconsin Carbonate Rocks

زمین‌شناسی، کانی‌سازی و ژئوشیمی تکI ، کانسار ماسیوسولفید پلی‌متال (Cu-Zn-Au-Ag-Pb) تکنار، خراسان- بردسکن

Rock unites which are exposed in Tak-I mine area are: Taknar formation (Ordovician), Mid-late Paleozoic and younger intrusive rocks. Taknar formation consists of sericite schist, chlorite schist, chlorite-sericite schist and some meta-diabase- gabbro-diorite. Taknar Polymetal (Cu-Zn-Au-Ag-Pb) Massive sulfide deposit formed at certain horizon of Taknar formation. Three style of mineralization ar...

Application of mineral chemistry to mineralization and alteration evaluation in Zn-Pb Angouran deposit, Zanjan

Angouran zinc and lead deposit is located about 135 km west of Zanjan city, in the northwest of the Sanandaj-Sirjan structural zone The results of this study indicate that the dolomitic alteration occurred in the carbonate hanging-wall and the presence of ankerite in the schist footwall. The main host of ore deposit is metamorphic carbonate. The Angouran dolomite is secondary and hydrothermal. ...
