Stratabound deposits within late Carboniferous carbonate units in the Middle–Lower Yangtze River metallogenic belt are important copper producers in China. Hitherto, the genesis of these deposits has been debated, due to poor constraints regarding the timing and source of the mineralization. Proposed models include a late Carboniferous seafloor exhalative formation (SEDEX), or an Early Cretaceo...

pb-zn deposits in the kurdistan region, northern iraq, have occurred mainly as a stratabound and open-space filling ore bodies. they are hosted by dolostone and dolomitic-limestone of platform carbonates. the ore deposits at the studied dure and lefan areas are respectively hosted by kurra chine (upper triassic) and bekhme (upper cretaceous) formations. pyrite, sphalerite and galena are the maj...

nakhlak lead mine is located at the nakhlak mountain 55 km ne of anarak town in isfahan province. the mineralogy is simple; galena and barite are the main primary minerals and cerussite is the main secondary mineral. sphalerite, pyrite, chalcopyrite, tetrahedrite-tennantite and acanthite occur as minor and trace mineral inclusions in galena. secondary minerals are anglesite, plattnerite, wulfen...

the komshecheh barite-fluorite deposit is the product of epigenetic hydrothermal mineralizationin dolomitized limestone of middle triassic age. the deposit is structurally and lithologically controlled andoccurs predominantly as bedded stratabound replacement sheets, although the veins and solution-collapsebreccias constitute important modes of occurrence. brecciation, dolomitization, silicific...
