GENESIS OF PB AND ZN DEPOSITS FROM NORTHERN IRAQ: CONSTRAINTS FROM STABLE ISOTOPIC AND FLUID INCLUSIONS CHARACTERISTICS

摘要

Lead-zinc deposits in Kurdistan Region, northern Iraq are occurred mainly as stratabound and open-space fillings ore bodies in the platform carbonates and hosted by dolostone and dolomitic-limestone. The ores at Dure and Lefan sections are hosted by Kurra Chine (Upper Triassic) and Bekhme (Upper Cretaceous) formations respectively. Pyrite, sphalerite and galena are the major sulfides, but the mineral paragenesis and relative proportions of these sulfides vary from deposit to other.
