Chapter 7 Lead-Zinc Deposits Bayaraa Batkhishig 7.1 Introduction Numerous researchers have conducted investigation on polymetallic and lead-zinc mineral systems in Mongolia. Significant researchers are V.A. Yakovlev, R. Kh. Bakhteev, I.A. Chijova, K.V. Podlessky, D.K. Aksuk, P.F. Vlasova, L.J. Naftali, V. Volkov, Ts. Konsulov, J. Lkhamsuren, Sh. Batjargal, D. Dorjgotov, Yu. B. Mironov, N.S. Soloviev, V.K. Lyvov, Yu. N. Pecherkin, B.M. Davidenko, N. Nirgev, D. Jargalsaihan, M. Kazmer, Z. Baras, D. Sanjaadorj, D. Garamjav, V. Kovachev, A.E. Fomenko, G.S. Ripp, V.I Sudakov, W.J. Nokleberg, O. Gerel, G. Dejidmaa, Kh. Gantumur, F.J. Dahlkamp, S.H. Jiang, F.J. Nie, S.K. Hu, H.Q. Yan and M. Ye. In this chapter a selected of polymetallic deposits are presented, including skarn Tumurtiin Ovoo; hydrothermal vein and stockwork Tsav, Dulaankhar, Mungun- Undur, Ulaan, Mukhar, Uulbayan and Nominy Am; and epithermal vein systems Khartolgoi, Kharmorit, Borts Uul, Burgedtas, and Bayan-Uul deposits. 7.2 Metallogeny and Distribution of Polymetallic Deposits in Mongolia Polymetallic (Pb-Zn  Ag, Cu) deposits and occurrences in Mongolia are different in terms of their geology, mineralogical characteristics, timing, and genetic pro- cesses. Therefore, researchers have suggested different classifications for the B.
